Powder Orange Isopods: An Overview
The Powder Orange is one of the most recognisable and widely kept isopod morphs in the hobby. Derived from selective breeding of Porcellionides pruinosus, this colour morph displays warm orange tones that contrast beautifully against dark substrate and create an eye-catching display in any enclosure.
P. pruinosus originates from the Mediterranean region but has become cosmopolitan through human activity. The scientific name translates roughly to "little pig covered in frost"—a reference to both the rounded body shape and the distinctive powdery texture of their exoskeleton. The Powder Orange morph was developed from the original Powder Blue through selective breeding for orange colouration.
These are genuinely one of the easiest isopod species to keep. Their tolerance for a wide range of conditions, prolific breeding, and voracious appetites make them ideal for beginners while remaining useful for experienced keepers building bioactive setups. The combination of striking colour and bulletproof hardiness explains their enduring popularity.
Currently on sale at £6 for 10 (down from £10), these represent exceptional value for such a vibrant, easy-to-keep species.
Powder Orange Isopods: Appearance
The defining feature is obviously the colour—warm orange tones ranging from pale peachy-tangerine to deeper, richer rust-orange depending on the individual and breeding line. The intensity can vary, with some specimens displaying vivid, almost glowing orange while others show softer, more muted tones.
Like all P. pruinosus, they have the characteristic powdery or velvety texture to their exoskeleton that gives the "Powder" isopods their name. This matte, frosted appearance comes from microscopic texturing on the carapace. The powder actually serves a functional purpose, increasing hydrophobicity and helping with moisture management.
Adults reach approximately 1-1.5cm in length, making them a small to medium-sized isopod. They have soft bodies compared to harder-shelled species like Armadillidium—they cannot roll into a ball when threatened and instead rely on their considerable speed to escape danger.
Juveniles may appear slightly paler initially, with colour deepening as they mature through successive moults. Just before moulting, specimens often display a particularly pronounced powdery appearance.
Powder Orange Isopods: Basic Care
These are about as close to "bulletproof" as isopods get. Their adaptability to various conditions makes them extremely forgiving of beginner mistakes.
Temperature: Room temperature works perfectly. They're comfortable anywhere from 18°C to 29°C, with around 21-25°C being ideal. They can tolerate temperature fluctuations that would stress more sensitive species.
Humidity: Moderate humidity (50-70%) suits them well. They're more tolerant of drier conditions than many isopod species, provided they have access to a moist area. Create a humidity gradient with one corner kept damper than the rest, allowing isopods to self-regulate their moisture exposure.
Ventilation: Moderate ventilation through small holes prevents stagnant conditions while maintaining humidity. They don't need aggressive airflow, but some air exchange helps prevent mould.
Lighting: Low light preferred, though they're notably more diurnal (daytime active) than many isopod species. You'll see them active during daylight hours as well as at night.
Powder Orange Isopods: Feeding
P. pruinosus have appetites that seem disproportionate to their small size. This voracious feeding behaviour is exactly what makes them such effective bioactive cleaners.
Primary Food Sources:
Mixed hardwood leaf litter (oak, beech, hazel—pesticide-free)
Decaying softwood
Rotting bark
Supplemental Foods:
Vegetables (carrot, courgette, sweet potato, cucumber, spinach)
Occasional fruit
Fish flakes or pellets for protein
Freeze-dried shrimp
Meat scraps (sparingly)
Commercial isopod diets
Calcium Sources: Essential for healthy moulting and exoskeleton maintenance:
Cuttlebone pieces
Limestone chips
Crushed eggshells
Calcium powder
Feeding Caution: While they need plenty of food to support their fast metabolism and breeding, avoid overfeeding with fresh foods. Uneaten vegetables attract pests like fungus gnats and mites. Provide only what can be consumed within 24-48 hours and remove any uneaten fresh items promptly.
Powder Orange Isopods: Substrate Mix
A moisture-retentive substrate with good structure works well. They're adaptable and not fussy about exact composition.
A suitable mix might include:
Coconut coir or peat moss as a moisture-retentive base
Organic topsoil mixed through
Sphagnum moss (especially in the moist area)
Decaying softwood pieces
Generous leaf litter as a top layer
Optional: earthworm castings for additional nutrition
Substrate depth of around 5-7cm is adequate. While P. pruinosus are primarily surface-active and don't burrow extensively, some depth allows for shelter and moisture regulation.
Powder Orange Isopods: Enclosure Setup
A straightforward setup suits this adaptable species. Nothing elaborate is required to keep them thriving.
Container Size: A 3-6 litre container works well for a starter colony of 10. Larger purchases (50-100) will need bigger enclosures or can be divided across multiple containers.
Moisture Gradient: Create distinct moisture zones. Keep one area with damp sphagnum moss while the remainder stays drier. This is important—they need access to moisture but shouldn't be kept uniformly wet.
Hides: Cork bark pieces, wood, and leaf litter provide shelter. While Powder Oranges are more visible than many species, they still appreciate hiding spots.
Ventilation: Small holes on alternating sides of the container provide adequate airflow without excessive drying.
Security: These are fast isopods. Ensure lids are secure with no gaps—they will find and exploit escape routes that slower species would ignore.
Cohabitation: Powder Oranges live well alongside springtails, which help control mould and process fine debris. Some keepers also house them with terrestrial snails in larger, humid setups.
Powder Orange Isopods: Breeding
P. pruinosus are famous for prolific breeding. Provide basic care and they'll multiply without any special encouragement.
Breeding Process:
Males transfer a spermatophore to females during mating
Females store sperm and fertilise eggs internally
Eggs develop in the female's marsupium (brood pouch)—visible as a whitish area between the legs
Fully-formed juveniles emerge from the marsupium
Juveniles moult through several stages before reaching adulthood
What to Expect:
Rapid reproduction once established
Large brood sizes
Sub-adults beginning to breed before reaching full size
Potentially explosive population growth in good conditions
Lifespan of 1-2 years, though captive specimens may live longer with consistent care
Colony growth can be remarkably fast. A starter culture of 10 can multiply many times over within months under good conditions. This prolific nature is one reason they're so popular as cleanup crews—they quickly establish self-sustaining populations that maintain themselves indefinitely.
Powder Orange Isopods: Behaviour
These are notably active, energetic isopods with distinctive behavioural traits.
Typical Behaviours:
Extremely fast—among the quickest isopods commonly kept
More diurnal than many species, active during daylight as well as at night
Surface-dwelling, spending most time in upper substrate layers
Voracious feeding, often descending on food in groups
Cannot roll into a ball—flee rapidly when disturbed
Social creatures that thrive in groups
Non-aggressive toward each other and enclosure inhabitants
Their combination of daytime activity and surface-dwelling habits means you'll see plenty of them. Watching a group of bright orange isopods moving across dark substrate is genuinely engaging—they're more entertaining to observe than many "fancier" species that spend most of their time hidden.
Handling Note: While non-aggressive and harmless, their soft bodies and speed make them unsuitable for regular handling. They're best observed rather than picked up. Young children should be supervised, as the isopods can be accidentally injured.
Powder Orange Isopods: Bioactive Use
Powder Oranges are among the most popular and effective bioactive cleanup crew isopods available.
Excellent for:
Tropical and humid bioactive setups
Temperate enclosures with moderate humidity
Reptile and amphibian vivariums
Display terrariums
Any setup where rapid waste processing is desired
Why they excel as cleanup crews:
Voracious appetites efficiently process waste, decaying matter, mould, and uneaten food
Prolific breeding maintains population without intervention
Surface-active nature means they encounter and process waste quickly
Bright colour adds visual interest to the enclosure
Soft bodies are palatable if pets occasionally snack on them
Adaptable to various enclosure conditions
Their soft exoskeletons make them suitable as occasional snacks for insectivorous pets like frogs and small lizards. The rapid reproduction compensates for any predation, and in smaller enclosures, some predation actually helps control population numbers.
Powder Orange Isopods: Comparing Powder Morphs
The Powder Orange is one of numerous colour morphs within the P. pruinosus species. All share identical care requirements.
Other P. pruinosus morphs we stock:

Powder Blue Isopods (Porcellionides Pruinosus)
£6.00
The original "Powder" isopod—the morph that started it all. Hardy, prolific, and arguably the most popular beginner isopod in the hobby.
Powder Blue Isopods: A Glimpse
Origin: Mediterranean, Southern Europe
Scientific Name: Porcellionides pruinosus
Difficulty Level: Very Easy
Size: Up to 1.5cm
Rarity: Low
Temperature: 18°C to 29°C
Humidity: 50% to 70% (moderate)
Favorite Foods: Leaf litter, decaying wood, vegetables, protein supplements
Supplements: Cuttlebone, limestone, crushed eggshells
Powder Blue Isopods: An Overview
The Powder Blue is where the Porcellionides pruinosus phenomenon began. This is the original morph that captured hobbyists' attention and launched an entire line of colour variants including Powder Orange, Oreo Crumble, and many others. If you've heard of "Powder isopods," this is the one that gave them their name.
Native to the Mediterranean region, P. pruinosus has become one of the most successful and widely distributed isopod species worldwide. The scientific name translates roughly to "little pig covered in frost"—a perfect description of their rounded bodies and distinctive dusty, frosted appearance. This powdery texture isn't just aesthetic; it's a microscopic surface feature that aids in moisture management and may help with camouflage.
These are genuinely among the easiest isopods to keep. They tolerate a wide range of conditions, breed prolifically, and work efficiently as bioactive cleanup crews. The Powder Blue has earned its reputation as the beginner isopod—forgiving enough for newcomers yet useful enough that experienced keepers still maintain colonies. There's a reason they remain popular despite all the fancier morphs now available.
Powder Blue Isopods: Appearance
The Powder Blue displays a distinctive blue-grey colouration that ranges from pale silver-blue to deeper slate or steel-blue tones depending on the individual and their stage in the moult cycle. The colour isn't a vibrant, saturated blue—it's more of a dusty, muted tone that gives them their characteristic "powdery" look.
The most striking colouration appears just before moulting, when specimens develop a particularly lustrous blue sheen with an almost metallic quality. This pre-moult appearance is what really catches the eye and demonstrates why they earned the "Powder Blue" name. Between moults, the colour may appear somewhat softer or more grey-toned.
Juveniles typically appear greyish, sometimes with a purplish undertone, transitioning through various shades as they mature. Watching the colour development through successive moults is part of the appeal of keeping a colony.
Like all P. pruinosus, they have soft bodies compared to harder-shelled species and reach approximately 1-1.5cm when fully grown. They cannot roll into a ball—when threatened, they rely on their considerable speed to flee. And they are fast; Powder Blues are among the quickest isopods commonly kept.
Powder Blue Isopods: Basic Care
This is about as close to foolproof as isopod keeping gets. P. pruinosus are remarkably adaptable and forgiving of imperfect conditions.
Temperature: Room temperature works perfectly. They're comfortable anywhere from 18°C to 29°C, with around 21-25°C being ideal for breeding. They tolerate temperature fluctuations that would stress more sensitive species.
Humidity: Moderate humidity (50-70%) suits them well. They're notably tolerant of drier conditions compared to many isopod species, making them suitable for a wider range of enclosure types. The key is providing a moisture gradient—one damp area while the rest can be drier—so they can self-regulate.
Ventilation: Moderate ventilation through small holes prevents stagnant conditions while maintaining humidity. Good airflow helps prevent mould without excessively drying the enclosure.
Lighting: Low light preferred. However, P. pruinosus are more diurnal than many isopod species, so you'll see plenty of activity during daylight hours—they're not purely nocturnal like some species.
Powder Blue Isopods: Feeding
Powder Blues have appetites that seem disproportionate to their small size. This voracious feeding is exactly what makes them such effective bioactive cleaners—they process organic waste efficiently and quickly.
Primary Food Sources:
Mixed hardwood leaf litter (oak, beech, hazel, magnolia—pesticide-free)
Decaying softwood and bark
Cork bark pieces
Supplemental Foods:
Vegetables (carrot, courgette, cucumber, sweet potato)
Fish flakes or pellets for protein
Freeze-dried shrimp
Meat scraps (sparingly)
Commercial isopod diets
Calcium Sources: Essential for healthy moulting and carapace maintenance:
Cuttlebone pieces
Crusite limestone
Crushed eggshells
Calcium powder
Feeding Caution: A common mistake is overfeeding. While they're hungry, providing too much fresh food attracts pests like fungus gnats, mites, and fruit flies. Offer only what can be consumed within 24-48 hours and remove uneaten fresh food promptly. Stick to vegetables rather than fruit, which is more likely to attract fruit flies.
Powder Blue Isopods: Substrate Mix
A moisture-retentive substrate with good structure works well. They're adaptable and not particularly fussy about exact composition.
A suitable mix might include:
Coconut coir or peat moss as a moisture-retentive base
Organic topsoil mixed through
Sphagnum moss (especially in the moist area—helps with humidity and moulting)
Decaying softwood and cork bark pieces
Generous leaf litter as a top layer
Optional: earthworm castings for additional nutrition
Optional: small amount of activated charcoal for substrate freshness
Substrate depth of around 5-7cm is adequate. While P. pruinosus are primarily surface-active, some depth allows for shelter and humidity regulation.
Powder Blue Isopods: Enclosure Setup
A straightforward setup suits this adaptable species. Nothing elaborate is required to keep them thriving.
Container Size: A 3-6 litre container works well for a starter colony of 10. Larger purchases (50-100) will need bigger enclosures or can be divided across multiple containers.
Moisture Gradient: This is the most important element. Keep one area with damp sphagnum moss while the remainder stays drier. Mist the wet side regularly with non-chlorinated water. You'll observe isopods migrating between moist and dry zones as they regulate their hydration.
Hides: Cork bark, rotting wood pieces, and leaf litter provide shelter and foraging opportunities. While Powder Blues are more visible than many species, they still appreciate places to retreat.
Ventilation: Small holes on alternating sides of the container provide adequate airflow. Avoid large ventilation openings—these fast isopods will find and exploit any escape routes.
Temperature Stability: Avoid placing enclosures where they'll experience sudden temperature swings. Consistent conditions promote better breeding.
Powder Blue Isopods: Breeding
P. pruinosus are famously prolific breeders. Provide basic care and they'll multiply without any special intervention.
What to Expect:
Rapid reproduction once established
Large brood sizes
Sub-adults beginning to breed before reaching full size
Colony establishment within weeks under good conditions
Potentially explosive population growth
Optimal breeding occurs around 24-27°C (mid-70s°F), though they'll breed across their entire comfortable temperature range. Well-fed colonies with appropriate humidity will grow quickly—sometimes faster than expected.
Population Management: In dedicated culture containers, monitor colony size and consider splitting when populations become dense. In bioactive setups, predation by enclosure inhabitants typically helps control numbers naturally.
Powder Blue Isopods: Behaviour
Powder Blues display the characteristic energetic behaviour of P. pruinosus—active, fast, and engaging to observe.
Typical Behaviours:
Extremely fast—among the quickest commonly kept isopods
More diurnal than many species, with good daytime activity
Surface-dwelling, spending most time in upper substrate layers and under bark
Voracious feeding, often converging on food sources in groups
Cannot roll into a ball—flee rapidly when disturbed
Social creatures that thrive in groups
Non-aggressive toward each other and tank inhabitants
Their combination of daytime activity and surface-dwelling habits makes them more visible than many isopod species. You'll regularly see them exploring, feeding, and interacting—they're genuinely entertaining to watch.
Speed Note: Their speed is no exaggeration. When disturbed, they scatter rapidly in all directions. This makes them challenging to catch or photograph, but it's also part of their charm. Secure enclosures are essential.
Powder Blue Isopods: Bioactive Use
Powder Blues are arguably the most popular bioactive cleanup crew isopod, and for good reason.
Excellent for:
Tropical and humid bioactive setups
Temperate enclosures
Semi-arid setups (they're more drought-tolerant than many species)
Reptile and amphibian vivariums
Display terrariums
Drier setups where other isopods might struggle
Why they excel as cleanup crews:
Voracious appetites efficiently process waste, decaying matter, mould, and uneaten food
Prolific breeding maintains population without intervention
Surface-active nature means they encounter and process waste quickly
Tolerant of varied conditions—work in setups ranging from humid to semi-arid
Soft bodies make them palatable to insectivorous pets
Affordable and readily available in bulk
Their soft exoskeletons make them excellent occasional snacks for frogs, small lizards, and other insectivores. The rapid reproduction compensates for any predation, creating a self-sustaining food source alongside their cleanup duties.
Powder Blue Isopods: The Original Powder Morph

Rainbow Mix Powdered isopods (Porcellionides Pruinosus)
£6.00
A living rainbow of colour morphs from the beloved Powder isopod line—multiple varieties in one mix for maximum visual impact.
Rainbow Mix Powdered Isopods: A Glimpse
Origin: Mediterranean Region (captive-bred colour morphs)
Scientific Name: Porcellionides pruinosus (mixed morphs)
Difficulty Level: Very Easy
Size: Up to 1.5cm
Rarity: Low
Temperature: 18°C to 27°C
Humidity: 50% to 70% (moderate to high)
Favorite Foods: Leaf litter, decaying wood, vegetables, protein supplements
Supplements: Cuttlebone, limestone, crushed eggshells, fish flakes
Rainbow Mix Powdered Isopods: An Overview
The Rainbow Mix is exactly what it sounds like—a curated selection of different Porcellionides pruinosus colour morphs combined into one visually striking collection. Rather than choosing a single colour, you get the full spectrum of what selective breeding has achieved with this species.
P. pruinosus is native to the Mediterranean but has become one of the most successful isopod species worldwide. The scientific name translates to "little pig covered in frost," referencing their rounded bodies and the distinctive powdery texture of their exoskeletons. Over years of captive breeding, numerous colour morphs have been developed, and this mix brings several of them together.
Your Rainbow Mix may include combinations of:
Powder Orange – warm, vibrant orange tones ranging from pale tangerine to deep rust
Powder Blue – the classic morph with metallic blue-grey colouration
White Out – pale, almost ghostly white specimens
Oreo Crumble – striking black and white piebald patterns
Orange Cream – mottled orange and cream variations
The exact composition varies depending on current stock, but the result is always a visually diverse colony that's far more interesting to observe than a single-colour population.
Rainbow Mix Powdered Isopods: Why Choose a Mix?
There are several reasons keepers opt for a Rainbow Mix over single-morph colonies:
Visual Interest: A multi-coloured colony is simply more engaging to watch. Different morphs scattered across your enclosure create a dynamic, varied display rather than a uniform appearance.
Genetics in Action: Since all P. pruinosus morphs can interbreed, a mixed colony lets you observe colour genetics playing out in real time. Offspring may inherit traits from both parents, creating interesting combinations and variations. Some keepers enjoy the unpredictability of what colours will emerge in subsequent generations.
Cost-Effective Variety: Rather than purchasing separate colonies of each morph, the Rainbow Mix lets you experience multiple colour forms at once for a single price point.
Excellent Value: At £6 for 10 isopods (with bulk options available), this represents outstanding value for a diverse, visually appealing starter colony.
Important Note: If you're interested in maintaining pure colour lines for breeding specific morphs, this mix isn't ideal—the morphs will interbreed freely. For pure lines, purchase single-morph colonies separately. But if you simply want an attractive, thriving colony and enjoy colour variation, the Rainbow Mix delivers.
Rainbow Mix Powdered Isopods: Appearance
All morphs in the Rainbow Mix share the characteristic P. pruinosus body shape and texture—small, oval bodies with that distinctive powdery or velvety surface that gives the "Powder" isopods their name. This frosted appearance comes from microscopic texturing on the exoskeleton, which actually serves a functional purpose in water management.
Adults reach approximately 1-1.5cm in length, making them a small to medium-sized isopod. The body is notably soft compared to harder-shelled species like Armadillidium—they cannot roll into a ball and rely on their considerable speed to escape threats.
Colour Variations You May See:
Blues ranging from pale grey-blue to deeper steel tones
Oranges from soft peach to vivid tangerine
Whites and creams
Piebald patterns mixing dark and light
Intermediate colours from crossbreeding
Juveniles often display bolder colours that develop a softer, more powdery sheen as they mature and moult. Watching the colour development across generations adds an extra dimension of interest to keeping a mixed colony.
Rainbow Mix Powdered Isopods: Basic Care
Care requirements are identical regardless of colour morph—all P. pruinosus share the same needs. This is one of the most forgiving isopod species available, tolerant of a wide range of conditions.
Temperature: Room temperature suits them perfectly. They're comfortable from 18°C to 27°C, with 21-25°C being ideal. Unless your home experiences extreme temperatures, they'll be fine without supplemental heating.
Humidity: Moderate to high humidity (50-70%) works well. They appreciate moisture but are more tolerant of drier conditions than many species, provided they have access to a damp area. Create a moisture gradient with one corner kept damper than the rest.
Ventilation: Moderate ventilation through small holes prevents stagnant conditions while maintaining humidity. Good airflow helps prevent mould without excessively drying the enclosure.
Lighting: Low light preferred, though they're notably more diurnal (daytime active) than many isopod species, giving you better viewing opportunities.
Rainbow Mix Powdered Isopods: Feeding
P. pruinosus have voracious appetites relative to their size. This hunger is what makes them such effective bioactive cleaners—they process organic matter quickly and efficiently.
Primary Food Sources:
Mixed hardwood leaf litter (oak, beech, hazel—pesticide-free)
Decaying softwood
Rotting bark
Supplemental Foods:
Vegetables (carrot, courgette, spinach, sweet potato, cucumber)
Occasional fruit
Fish flakes or pellets for protein
Freeze-dried shrimp
Commercial isopod diets
Calcium Sources: Essential for healthy moulting across all colour morphs:
Cuttlebone pieces
Limestone chips
Crushed eggshells
Calcium powder
Feed supplemental foods 2-3 times weekly, providing only what can be consumed within 24-48 hours. Their enthusiasm for food means they'll quickly descend on anything offered, but remove uneaten fresh items to prevent mould and pest attraction.
Rainbow Mix Powdered Isopods: Substrate Mix
A moisture-retentive substrate with good structure works well. The exact composition is less critical than getting the basics right—P. pruinosus are adaptable.
A suitable mix might include:
Coconut coir or peat moss as a moisture-retentive base
Organic topsoil mixed through
Sphagnum moss (especially in the moist area)
Decaying softwood pieces
Generous leaf litter as a top layer
Optional: earthworm castings for additional nutrition
Substrate depth of around 5-7cm is adequate. While P. pruinosus are primarily surface-active, some substrate depth allows for shelter and moisture regulation.
Rainbow Mix Powdered Isopods: Enclosure Setup
A straightforward setup suits this adaptable species. Nothing elaborate is required.
Container Size: A 3-6 litre container works well for a starter colony. Bulk purchases (50-100) will need larger enclosures or can be divided across multiple containers.
Moisture Gradient: Essential for all isopod keeping. Keep one area with damp sphagnum moss while the remainder stays drier. This allows individual isopods to regulate their moisture exposure.
Hides: Cork bark pieces and leaf litter provide shelter. While P. pruinosus are more visible than many species, they still appreciate hiding spots.
Ventilation: Small holes on alternating sides of the container provide adequate airflow. Secure lids are important—these are fast isopods and will exploit any escape routes.
Security Note: P. pruinosus are remarkably quick. Ensure your enclosure is secure, as they will find and exploit gaps that slower species would ignore.
Rainbow Mix Powdered Isopods: Breeding
All P. pruinosus morphs breed prolifically, and the Rainbow Mix is no exception. Expect rapid population growth once the colony establishes.
What to Expect:
Fast reproduction across all colour morphs
Large brood sizes
Sub-adults breeding before reaching full size
Potentially explosive population growth in good conditions
Colour variation in offspring as morphs interbreed
Genetics Note: Because all morphs in the mix are the same species, they will freely interbreed. Over generations, you may see:
Pure-coloured offspring matching one parent
Intermediate colours blending parental traits
Occasional throwbacks to colours not obviously present in the parents
Gradual shifts in colony colour composition based on which traits prove dominant
This genetic mixing is part of the appeal for many keepers—each generation brings surprises. However, if maintaining pure colour lines matters to you, keep morphs in separate colonies.
Rainbow Mix Powdered Isopods: Behaviour
P. pruinosus are among the most active and energetic isopods commonly kept, regardless of colour morph.
Typical Behaviours:
Extremely fast—some of the quickest isopods you'll encounter
More diurnal than many species, active during daylight hours
Surface-dwelling, spending most time in upper substrate layers
Voracious feeding, often descending on food in groups
Rapid, almost frenetic antenna movements
Cannot roll into a ball—flee when disturbed
Active both day and night, especially around feeding times
Their combination of daytime activity and surface-dwelling habits means you'll see plenty of your Rainbow Mix. The varied colours moving across the substrate create an engaging display that single-colour colonies can't match.
Rainbow Mix Powdered Isopods: Bioactive Use
P. pruinosus are among the most popular and effective bioactive cleanup crew isopods, and the Rainbow Mix adds visual appeal to their functional benefits.
Excellent for:
Tropical and humid bioactive setups

Powder Orange Dalmatian Isopods: An Overview
The Orange Dalmatian is a pied colour morph of Porcellionides pruinosus, displaying orange spotting and patterning on a lighter base colour. It's closely related to other pied morphs like the Oreo Crumble and Orange Cream, but with its own distinctive warm-toned appearance that's reminiscent of the spots on a Dalmatian dog—hence the name.
Like all P. pruinosus morphs, the Orange Dalmatian inherits the species' legendary hardiness and adaptability. These are among the most forgiving isopods available, tolerating a wide range of temperatures and humidity levels while breeding prolifically. The combination of attractive patterning and bulletproof care requirements makes them an excellent choice for beginners who want something more visually interesting than plain-coloured morphs.
The Orange Dalmatian morph is sometimes also sold under names like "Orange Pied" or confused with the similar "Orange Cream" morph. While there's variation in how different breeders define these morphs, our Orange Dalmatians display the characteristic spotted pattern with orange pigmentation on a lighter background.

The defining feature of this morph is the dalmatian-style patterning—irregular orange spots, blotches, and speckling distributed across the body. The base colour is typically a pale cream, off-white, or low-opacity orange-brown, with the darker orange markings creating contrast.
One of the fascinating aspects of this morph is how the pattern develops with age. Juveniles often appear predominantly pale or whitish, with the orange patterning becoming more pronounced and vibrant as they mature through successive moults. This colour development means a colony displays a range of appearances, from pale youngsters to boldly-marked adults.
Like all P. pruinosus, they have the characteristic powdery or velvety texture to their exoskeleton—the frosted appearance that gives "Powder" isopods their name. Adults reach approximately 1-1.5cm in length, making them a small to medium-sized isopod.
They have soft bodies compared to harder-shelled genera like Armadillidium and cannot roll into a ball. When threatened, they rely on their considerable speed to flee rather than defensive curling.
Powder Orange Dalmatian Isopods: Basic Care
Care requirements are identical to other P. pruinosus morphs. This is one of the most adaptable isopod species available, tolerating conditions that would stress more sensitive species.
Temperature: Room temperature works perfectly. They're comfortable anywhere from 18°C to 29°C, with around 21-25°C being ideal. Temperature fluctuations that would concern you with other species are generally fine for Powder isopods.
Humidity: Moderate humidity (50-70%) suits them well. They're more tolerant of variation than many species—comfortable in both slightly humid and semi-arid conditions as long as they have access to a moist area. Create a humidity gradient with one section kept damp while the rest can be drier.
Ventilation: Moderate ventilation through small holes prevents stagnant conditions while maintaining humidity. Good airflow helps prevent mould.
Lighting: Low light preferred, though P. pruinosus are notably more diurnal than many isopod species, so you'll see activity during daylight hours as well as at night.
Powder Orange Dalmatian Isopods: Feeding
P. pruinosus have voracious appetites relative to their size—they're enthusiastic feeders that make highly effective bioactive cleaners.
Primary Food Sources:
Mixed hardwood leaf litter (oak, beech, hazel—pesticide-free)
Decaying softwood
Rotting bark
Supplemental Foods:
Vegetables (carrot, courgette, cucumber, sweet potato, mushrooms)
Occasional fruit
Fish flakes or pellets for protein
Freeze-dried shrimp
Commercial isopod diets
Calcium Sources: Essential for healthy moulting and shell development:
Cuttlebone pieces
Limestone chips
Crushed eggshells
Oyster shell
Calcium powder
Remove uneaten fresh food within 24-48 hours to prevent mould and pest attraction. Leaf litter and decaying wood can remain in the enclosure permanently.
Powder Orange Dalmatian Isopods: Substrate Mix
A moisture-retentive substrate with good structure works well. P. pruinosus are adaptable and not fussy about exact composition.
A suitable mix might include:
Coconut coir or peat moss as a moisture-retentive base
Organic topsoil mixed through
Sphagnum moss (especially in the moist area)
Decaying softwood pieces
Generous leaf litter as a top layer
Optional: earthworm castings for additional nutrition
Substrate depth of around 5-7cm is adequate. P. pruinosus are primarily surface-active rather than burrowers, but some depth allows for shelter and humidity regulation.
Powder Orange Dalmatian Isopods: Enclosure Setup
A straightforward setup suits this adaptable species. Nothing elaborate is required.
Container Size: A 3-6 litre container works well for a starter colony. Larger purchases will need bigger enclosures or can be divided across multiple containers.
Moisture Gradient: Create distinct moisture zones. Keep one area with damp sphagnum moss while the remainder stays drier. You'll often observe isopods migrating between moist and dry areas as they regulate their hydration.
Hides: Cork bark pieces, lotus pods, and leaf litter provide shelter. While Powder isopods are more visible than many species, they appreciate hiding spots—you'll often find them congregating under bark.
Ventilation: Small holes on alternating sides of the container provide adequate airflow without excessive drying.
Security: These are fast isopods that will exploit any escape routes. Ensure lids are secure with no gaps.
Powder Orange Dalmatian Isopods: Breeding
Like all P. pruinosus morphs, Orange Dalmatians breed prolifically. Provide basic care and they'll multiply without special encouragement.
What to Expect:
Rapid reproduction once established
Large brood sizes
Sub-adults beginning to breed before reaching full size
Fast colony growth
Pattern development in offspring—pale juveniles gradually developing orange markings
Colour Inheritance: Offspring generally breed true to the Orange Dalmatian pattern, though natural variation means some individuals will display more or less orange than others. The intensity and distribution of markings varies between specimens, adding visual interest to a colony.
Note: If you house Orange Dalmatians with other P. pruinosus morphs, they will interbreed. Offspring may show mixed characteristics rather than pure Orange Dalmatian patterning. Keep separate if maintaining pure morph lines is important to you.
Powder Orange Dalmatian Isopods: Behaviour
These display the typical active, energetic behaviour of P. pruinosus.
Typical Behaviours:
Extremely fast—among the quickest commonly kept isopods
More diurnal than many species, with good daytime visibility
Surface-dwelling, spending most time in upper substrate layers
Voracious feeding behaviour
Cannot roll into a ball—flee when disturbed
Social creatures that thrive in groups
Non-aggressive toward each other and tank inhabitants
You'll often observe them migrating between moist and dry areas of the enclosure, particularly after misting. Their combination of daytime activity and surface-dwelling habits means you'll see plenty of your colony, with the varied orange patterning creating an attractive display.
Powder Orange Dalmatian Isopods: Bioactive Use
Orange Dalmatians are excellent bioactive cleanup crew members, combining effective waste processing with visual appeal.
Excellent for:
Tropical and humid bioactive setups
Temperate enclosures with moderate humidity

Porcellionides Pruinosus 'Oreo Crumble' Isopods: An Overview
The Oreo Crumble is a piebald colour morph of Porcellionides pruinosus, the same species that gave us the immensely popular Powder Blue and Powder Orange isopods. The scientific name translates roughly to "little pig covered in frost"—a reference to both their rounded body shape and the distinctive powdery appearance of their exoskeleton.
P. pruinosus is native to the Mediterranean but has become truly cosmopolitan, spread across the world through human activity. It's one of the most successful and adaptable isopod species, which translates directly into ease of care in captivity. These are about as close to "bulletproof" as isopods get.
The Oreo Crumble morph displays a striking black and white piebald pattern—dark base colouration broken up with bright white or cream markings. Legend has it the name came from a breeder asking their daughter what the new morph looked like, and she replied "Oreo Crumbles!" The name stuck, and it's certainly apt.
At £6 for 10, these represent excellent value for a visually striking morph that will establish quickly and breed prolifically.
Porcellionides Pruinosus 'Oreo Crumble' Isopods: Appearance
The defining feature of the Oreo Crumble morph is the piebald colouration—a dark grey or black base colour broken up with irregular white or cream patches and spots. The pattern varies between individuals, making each isopod slightly unique. Juveniles typically display bolder, more contrasting colours that take on a softer, powdery sheen as they mature.
Like all P. pruinosus, they have a characteristic powdery or velvety appearance to their exoskeleton. This isn't dirt or coating—it's a microscopic texture on the carapace that gives them their distinctive matte, frosted look. This powdery surface actually serves a function, increasing hydrophobicity and helping with water management.
Adults reach approximately 1-1.5cm in length, making them a small to medium-sized isopod. They're noticeably smaller and more delicate than visually similar species like Porcellio laevis 'Dairy Cow', which is sometimes confused with Oreo Crumbles but is a completely different species.
The body is soft compared to harder-shelled species like Armadillidium. They cannot roll into a ball when threatened—instead, they rely on their considerable speed to escape danger.
Porcellionides Pruinosus 'Oreo Crumble' Isopods: Basic Care
These are genuinely one of the easiest isopod species to keep. Their tolerance for a wide range of conditions makes them forgiving of beginner mistakes and adaptable to various setups.
Temperature: Room temperature works perfectly. They're comfortable anywhere from 18°C to 29°C, though 21-26°C is ideal. Unless your house is freezing or sweltering, they'll be fine.
Humidity: They appreciate higher humidity levels (60-85%) but are adaptable. The key is providing a moisture gradient—one area kept damp while the rest can be drier. They need access to moisture but shouldn't be waterlogged. Good ventilation helps prevent mould while maintaining appropriate humidity.
Ventilation: Moderate ventilation is important. Small ventilation holes are sufficient—they don't need aggressive airflow, but stagnant, overly moist conditions encourage mould.
Lighting: Low light preferred. They're more active in darker conditions, though they're notably more diurnal (daytime active) than many isopod species.
Porcellionides Pruinosus 'Oreo Crumble' Isopods: Feeding
One thing you'll quickly notice about Oreo Crumbles: they have voracious appetites. For their size, they eat a surprising amount. This is actually what makes them such effective bioactive cleaners.
Primary Food Sources:
Mixed hardwood leaf litter (oak, beech, hazel)
Decaying softwood
Rotting bark
Supplemental Foods:
Vegetables (cucumber, courgette, carrot, squash, sweet potato)
Occasional fruit
Fish flakes or pellets for protein
Freeze-dried shrimp
Commercial isopod foods
Calcium Sources: Essential for healthy moulting. Provide:
Cuttlebone pieces (they seem to love this)
Limestone chips
Crushed eggshells
Calcium powder
A word of caution: while they need plenty of food to support their fast metabolism and reproduction, avoid excessive overfeeding with fresh foods. Uneaten vegetables left too long can attract unwanted pests like mites. Remove fresh food within a day or two if uneaten.
Porcellionides Pruinosus 'Oreo Crumble' Isopods: Substrate Mix
A moisture-retentive substrate with good structure suits this species well. They're not fussy about exact composition as long as basic needs are met.
A suitable mix might include:
Coconut coir or peat moss as a moisture-retentive base
Organic topsoil mixed through
Sphagnum moss (particularly in the moist area)
Decaying softwood pieces
Leaf litter as a top layer
Earthworm castings for nutrition
Substrate depth of around 5-7cm allows for some burrowing, though P. pruinosus are primarily surface-active and don't burrow extensively.
Porcellionides Pruinosus 'Oreo Crumble' Isopods: Enclosure Setup
A straightforward setup works well. These adaptable isopods don't require elaborate arrangements.
Container Size: A 3-6 litre container suits a starter colony well. They don't need vast space individually, but will appreciate room as numbers increase.
Moisture Gradient: Create distinct moisture zones. Keep one area with damp sphagnum moss while the rest stays drier. This allows the isopods to regulate their moisture exposure according to their needs.
Hides: Cork bark pieces, leaf litter, and wood provide shelter. While these isopods are more visible than many species, they still appreciate hiding spots.
Ventilation: Small holes on alternating sides of the container provide adequate airflow without excessive drying.
Porcellionides Pruinosus 'Oreo Crumble' Isopods: Breeding
P. pruinosus are famous for their prolific breeding. This is a "set and forget" species when it comes to reproduction—provide basic care and they'll multiply without any special encouragement.
What to Expect:
Rapid reproduction once established
Large brood sizes
Females carrying eggs in a visible marsupium (brood pouch)
Sub-adults beginning to breed before reaching full size
Potentially explosive population growth
Colony growth can be remarkably fast. In good conditions, a starter culture can multiply many times over within months. This prolific nature is one reason they're so popular as cleanup crews—they quickly establish self-sustaining populations.
In the wild, P. pruinosus live approximately 11-14 months, though captive specimens may live somewhat longer with consistent care.
Porcellionides Pruinosus 'Oreo Crumble' Isopods: Behaviour
These are notably active, energetic isopods with some distinctive behavioural traits.
Typical Behaviours:
Fast—extremely fast. These are some of the quickest isopods you'll encounter
More diurnal than many species, providing better daytime viewing opportunities
Surface-active, spending most time in the upper substrate layers and on surfaces
Voracious feeding, descending on food sources in groups
Rapid antenna movements—almost frenetic compared to calmer species
Fleeing rather than rolling when disturbed (they cannot conglobate)
Their speed and energy make them entertaining to observe but challenging to photograph! The combination of daytime activity and surface-dwelling behaviour means you'll see more of these isopods than many secretive species.
They're social creatures that thrive in groups and show no aggression toward each other or enclosure inhabitants.
Porcellionides Pruinosus 'Oreo Crumble' Isopods: Bioactive Use
P. pruinosus are among the most popular and effective bioactive cleanup crew isopods available. Their combination of traits makes them ideal for this role.
Excellent for:
Tropical and humid bioactive setups
Temperate enclosures with moderate humidity
Reptile and amphibian vivariums
Display terrariums
Any setup where rapid population establishment is desired
Why they excel as cleanup crews:
Voracious appetites—they'll consume waste, decaying matter, mould, and uneaten food efficiently
Prolific breeding maintains population without intervention
Surface-active nature means they encounter and process waste quickly
Soft bodies make them palatable to insectivorous animals as an occasional bonus snack
Tolerant of various conditions
Their soft bodies mean insectivorous pets may enjoy the occasional isopod snack. This is generally fine—the rapid reproduction compensates for any predation, and in fact, pets eating some isopods helps control populations in smaller enclosures.
One caution: In rare cases, starving isopods may attempt to nibble on freshly moulted invertebrates or very small, delicate animals. Always provide supplemental food to your cleanup crew to prevent this.
Porcellionides Pruinosus 'Oreo Crumble' Isopods: Comparing Powder Morphs
The Oreo Crumble is one of numerous colour morphs within the P. pruinosus species. All share identical care requirements and can technically interbreed, though most keepers maintain separate colonies to preserve colour genetics.
Other popular P. pruinosus morphs include:
Powder Blue (the original popular morph—blue-grey colouration)
Powder Orange (vibrant orange)
Orange Cream (mottled orange, visually closest to Oreo Crumble)
White Out (predominantly white)
Red Koi (red and white pattern)
The Oreo Crumble offers more visual interest than plain colour morphs while remaining just as easy to care for.

Powder White Isopods: An Overview
The Powder White (sometimes called "White Out") is a striking pale morph of Porcellionides pruinosus that's been selectively bred for its bright, clean white colouration. While the original Powder Blue displays dusty blue-grey tones, the Powder White takes the species in the opposite direction—a ghostly, almost luminous appearance that stands out beautifully against dark substrate.
Like all P. pruinosus morphs, Powder Whites inherit the species' legendary hardiness and adaptability. These are among the most forgiving isopods available, tolerating a wide range of conditions while breeding prolifically. The combination of eye-catching appearance and bulletproof care requirements makes them ideal for beginners who want something visually distinctive.
At just £5 for 10 (with bulk options available), Powder Whites offer excellent value for such an attractive morph. They're one of the most affordable ways to add visual interest to a bioactive setup or start an isopod collection.
Powder White Isopods: Appearance
The defining characteristic is the pale, white colouration that gives them their name. Juveniles typically display a bright, clean white that's particularly striking. As they mature, the colour may develop a slightly shimmery or pearlescent quality, though they remain predominantly white throughout their lives.
Like all P. pruinosus, they have the characteristic powdery or velvety texture to their exoskeleton—the frosted appearance that defines the "Powder" isopod line. This microscopic surface texture helps with moisture management and gives them their distinctive matte finish.
Adults reach approximately 1-1.5cm in length, making them a small to medium-sized isopod. They have soft bodies compared to harder-shelled genera and cannot roll into a ball. When threatened, they rely on their considerable speed to escape—and they are genuinely fast.
The white colouration makes them highly visible against dark substrate, which is both an advantage (easy to observe) and something to consider for bioactive setups where you might prefer a more camouflaged cleanup crew.
Powder White Isopods: Basic Care
Care requirements are identical to other P. pruinosus morphs. This is one of the most adaptable isopod species available.
Temperature: Room temperature works perfectly. They're comfortable anywhere from 18°C to 29°C, with around 21-25°C being ideal. They tolerate temperature fluctuations that would stress more sensitive species.
Humidity: Moderate humidity (50-70%) suits them well. They're adaptable across a range from semi-arid to humid conditions, making them suitable for various enclosure types. Create a moisture gradient with one damp area while the rest can be drier.
Ventilation: Good ventilation is important. Small holes on alternating sides of the container prevent stagnant conditions while maintaining humidity.
Lighting: Low light preferred, though P. pruinosus are notably more diurnal than many isopod species. You'll see plenty of activity during daylight hours—their white colouration makes them particularly easy to spot when they're moving about.
Powder White Isopods: Feeding
P. pruinosus are enthusiastic feeders with appetites that seem disproportionate to their small size. This voracious feeding makes them highly effective bioactive cleaners.
Primary Food Sources:
Mixed hardwood leaf litter (oak, beech, hazel—pesticide-free)
Decaying softwood
Rotting bark and wood pieces
Supplemental Foods:
Vegetables (carrot is a particular favourite, along with sweet potato, peas, courgette, mushrooms)
Dried shrimp (another favourite)
Fish flakes or pellets for protein
Yeast
Commercial isopod diets
Calcium Sources: Essential for healthy moulting:
Cuttlebone pieces
Limestone chips
Crushed eggshells
Calcium powder
Feeding Caution: Never overfeed. Leftover food particles encourage fungal growth and attract pests like mites and fungus gnats. Provide only what can be consumed within 24-48 hours and remove any uneaten fresh food promptly.
Powder White Isopods: Substrate Mix
A moisture-retentive substrate with good structure works well. They're adaptable and not fussy about exact composition.
A suitable mix might include:
Coconut coir as a moisture-retentive base
Peat moss mixed through
Sphagnum moss (especially in the moist area)
Decaying softwood pieces
Generous leaf litter as a top layer
Substrate depth of around 5-7cm is adequate. P. pruinosus are primarily surface-active rather than burrowers, but some depth provides shelter and humidity regulation.
Note on Visibility: Powder Whites show up beautifully against dark substrate. If you want maximum visual impact, use a darker substrate mix. Against pale substrates, they'll be harder to see.
Powder White Isopods: Enclosure Setup
A straightforward setup suits this adaptable species. Nothing elaborate is required.
Container Size: A 3-6 litre container works well for a starter colony. Transparent containers are particularly good for Powder Whites—their active nature and pale colouration make them entertaining to observe.
Moisture Gradient: Keep one area with damp substrate or sphagnum moss while the remainder stays drier. Mist the moist side periodically with dechlorinated water.
Hides: Cork bark, lotus pods, coconut halves, and leaf litter provide shelter. While Powder Whites are highly active and visible, they appreciate hiding spots—you'll often find them congregating under bark, especially when first introduced to a new environment.
Ventilation: Essential. These isopods need good airflow. Small holes on alternating sides work well.
Security: These are fast isopods. Secure lids are essential—they will find and exploit any escape routes.
Powder White Isopods: Breeding
Like all P. pruinosus, Powder Whites are prolific breeders. They're known for establishing colonies remarkably quickly.
What to Expect:
Rapid reproduction once established
Large brood sizes
Sub-adults beginning to breed before reaching full size
Fast colony growth—among the quickest to establish of common isopod species
Consistent white colouration in offspring
One notable characteristic of P. pruinosus is that they can begin breeding before reaching full adult size. This, combined with their large brood sizes and short generation time, means colonies can grow surprisingly fast under good conditions.
Colour Stability: Powder Whites generally breed true, producing white offspring. If housed with other P. pruinosus morphs, they will interbreed and offspring may show mixed characteristics.
Powder White Isopods: Behaviour
Powder Whites display the characteristic energetic behaviour of P. pruinosus.
Typical Behaviours:
Extremely fast—among the quickest commonly kept isopods
Highly active, constantly on the move
More diurnal than many species, with excellent daytime visibility
Surface-dwelling, spending most time in upper substrate layers
Voracious feeding behaviour
Cannot roll into a ball—flee rapidly when disturbed
Initially shy in new environments, hiding under leaf litter until comfortable
Social creatures that thrive in groups
Their active, visible nature makes them particularly entertaining to watch. The white colouration against dark substrate creates a striking display as they scurry about foraging and exploring. They're genuinely engaging to observe—more so than many "fancier" species that spend most of their time hidden.
Powder White Isopods: Bioactive Use
Powder Whites make excellent bioactive cleanup crew members, with some unique considerations due to their colouration.
Excellent for:
Bioactive setups where visual interest matters
Enclosures where you want to easily monitor cleanup crew activity
Humid to semi-arid setups
Reptile and amphibian vivariums
Display terrariums
Why they excel as cleanup crews:
Voracious appetites efficiently process waste, decaying matter, and mould
Prolific breeding maintains population without intervention
Surface-active nature means they encounter and process waste quickly
Soft bodies make them palatable to insectivorous pets
Highly visible—easy to monitor population health
Visibility Consideration: Their white colouration makes them highly conspicuous. This is an advantage if you want to observe your cleanup crew in action, but worth considering if you prefer a more "natural" look where the cleanup crew blends into the environment. For setups where you'd rather not see the isopods, other morphs like Powder Blue may be more suitable.
As Feeders: Their surface-dwelling, active nature combined with soft bodies makes them excellent occasional food for insectivorous pets. They keep pets engaged by requiring active hunting rather than being easy catches.
Powder White Isopods: Comparing to Other Powder Morphs
The Powder White is one of several colour morphs within P. pruinosus. All share identical care requirements.
How Powder White compares:
Powder Blue – The original morph; dusty blue-grey; most widely available
Powder Orange – Warm orange tones; high contrast against substrate
Powder White – Pale, ghostly white; maximum visibility; slightly less common
Oreo Crumble – Black and white piebald; striking contrast
Orange Dalmatian – Orange spotting on pale base; patterned variant
Powder White is arguably the most visible of all the morphs due to the bright, clean colouration. If you want isopods you can easily see and monitor, this is an excellent choice.
Other P. pruinosus morphs we stock:

£6.00
The original, unmodified P. pruinosus—natural wild-type colouration from a Caribbean locality, with all the hardiness the species is famous for.
Wild Type Guadeloupe Powdered Isopods: A Glimpse
Origin: Guadeloupe, French Caribbean (Lesser Antilles)
Scientific Name: Porcellionides pruinosus
Difficulty Level: Very Easy
Size: Up to 1.2cm
Rarity: Low (uncommon locality)
Temperature: 18°C to 29°C
Humidity: 60% to 80% (moderate to high)
Favorite Foods: Leaf litter, decaying wood, vegetables, protein supplements
Supplements: Cuttlebone, limestone, crushed eggshells
Wild Type Guadeloupe Powdered Isopods: An Overview
While the hobby is full of selectively bred colour morphs—Powder Blue, Powder Orange, Oreo Crumble, and many others—this is Porcellionides pruinosus as nature intended. The Wild Type Guadeloupe represents the species in its natural, unmodified form, displaying the original colouration that wild populations exhibit.
These specimens originate from Guadeloupe, a French Caribbean island in the Lesser Antilles. P. pruinosus is native to the Mediterranean but has become cosmopolitan, establishing populations across the world including the Caribbean. The Guadeloupe locality represents an interesting population that's adapted to tropical island conditions.
What you get with wild-type isopods is the natural colour variation that selective breeding removes. Rather than the uniform appearance of colour morphs, wild-type specimens display a range of subtle greys, browns, and muted tones—the natural camouflage colouration that's served the species well in the wild. They still show the characteristic powdery texture that defines the species, but without the vivid blues, oranges, or whites of captive-bred morphs.
For keepers interested in the species as it exists naturally, or those who prefer a more subdued, natural appearance for their bioactive setups, the wild type offers something the colour morphs can't provide: authenticity.
Wild Type Guadeloupe Powdered Isopods: Appearance
Wild-type P. pruinosus display natural camouflage colouration rather than the uniform colours of selectively bred morphs. Expect a range of earthy tones including greys, browns, and subtle muted shades. Some individuals may show hints of the bluish-grey that was developed into the Powder Blue morph, while others lean more towards brown or grey-brown tones.
Like all P. pruinosus, they have the characteristic powdery or dusty texture to their exoskeleton—the frosted appearance that becomes particularly pronounced before moulting. This powdery coating is the species' signature feature regardless of colour morph.
Adults reach approximately 1-1.2cm in length, making them a small to medium-sized isopod. They have soft bodies and cannot roll into a ball—when threatened, they rely on their considerable speed to escape.
The natural colour variation within a colony can actually be quite attractive in its own right. Rather than the uniformity of a colour morph, you'll see a range of subtle variations that creates a more natural, organic appearance.
Wild Type Guadeloupe Powdered Isopods: Basic Care
Care is identical to other P. pruinosus—this is the same hardy, adaptable species regardless of colour form.
Temperature: Room temperature works perfectly. They're comfortable from 18°C to 29°C. Their Caribbean origin means they're well-suited to slightly warmer conditions, though they're adaptable across the typical range.
Humidity: Moderate to high humidity (60-80%) suits them well. As with all P. pruinosus, create a moisture gradient with one damp area while the rest can be drier. They're forgiving of fluctuations.
Ventilation: Good ventilation is important. Small holes on multiple sides of the container prevent stagnant conditions.
Lighting: Low light preferred, though they're notably diurnal and will be active during daylight hours.
Wild Type Guadeloupe Powdered Isopods: Feeding
Feeding requirements are identical to colour morphs—P. pruinosus are enthusiastic, voracious feeders regardless of colouration.
Primary Food Sources:
Mixed hardwood leaf litter (oak, beech, hazel—always available)
Decaying softwood
Rotting bark
Supplemental Foods:
Vegetables (carrot, sweet potato, cucumber, courgette, squash)
Fish flakes for protein
Freeze-dried shrimp
Occasional fruit (apple, banana—in moderation)
Commercial isopod diets
Calcium Sources:
Cuttlebone pieces
Limestone chips
Crushed eggshells
Feed supplemental foods 2-3 times weekly. Remove uneaten fresh food within 24-48 hours to prevent mould and pest attraction. Leaf litter should always be available.
Wild Type Guadeloupe Powdered Isopods: Substrate Mix
A moisture-retentive substrate works well. They're not fussy about exact composition.
A suitable mix might include:
Organic topsoil or potting compost as a base (pesticide-free)
Coconut coir or peat moss for moisture retention
Sphagnum moss (especially in the moist area)
Earthworm castings for nutrition
Generous leaf litter as a top layer
Limestone chips for calcium
Substrate depth of around 5-7cm is adequate. P. pruinosus are primarily surface-dwelling and don't burrow extensively.
Wild Type Guadeloupe Powdered Isopods: Enclosure Setup
A straightforward setup suits this adaptable species.
Container Size: A 3-6 litre container works well for a starter colony. Larger for bulk purchases.
Moisture Gradient: Keep one area with damp substrate or sphagnum moss while the remainder stays drier.
Hides: Cork bark pieces and leaf litter provide shelter. Simple setups work perfectly—these aren't demanding isopods.
Ventilation: Multiple small holes on alternating sides provide adequate airflow.
Security: Fast isopods require secure enclosures. Ensure lids fit properly with no gaps.
Wild Type Guadeloupe Powdered Isopods: Breeding
P. pruinosus are famously prolific breeders, and the wild type is no exception.
What to Expect:
Rapid reproduction once established
Large brood sizes (females can produce 30-50 offspring per cycle)
Fast maturation—sub-adults breeding before full size
Potentially explosive population growth
Natural colour variation maintained in offspring
Slightly warmer temperatures (around 24-27°C) encourage faster reproduction, though they'll breed across their comfortable temperature range.
Genetics Note: Unlike colour morphs that breed true to a specific appearance, wild-type offspring will display the natural range of colour variation. This maintains the authentic wild appearance across generations.
Wild Type Guadeloupe Powdered Isopods: Behaviour
Wild-type specimens display the same characteristic P. pruinosus behaviour as colour morphs.
Typical Behaviours:
Extremely fast—among the quickest commonly kept isopods
Highly active, particularly during daylight hours
Surface-dwelling, spending most time in upper substrate layers
Voracious feeding
Cannot roll into a ball—flee when disturbed
Social creatures thriving in groups
Their active, surface-dwelling nature makes them highly visible despite their camouflage colouration. You'll see plenty of movement and activity in a healthy colony.
Wild Type Guadeloupe Powdered Isopods: Bioactive Use
Wild-type P. pruinosus are just as effective as cleanup crews as their colour morph cousins.
Excellent for:
Naturalistic bioactive setups where camouflaged cleanup crews are preferred
Tropical and humid enclosures
Reptile and amphibian vivariums
Display terrariums where a natural aesthetic matters
Any setup benefiting from efficient waste processing
Advantages of Wild Type for Bioactive:
Natural colouration blends into the environment
Less visually intrusive than bright colour morphs
Same prolific breeding and voracious appetites
Authentic, natural appearance
Soft bodies palatable to insectivorous pets
For keepers who prefer their cleanup crew to blend into the environment rather than stand out, wild-type isopods are the logical choice.
Wild Type vs Colour Morphs: Which to Choose?
Choose Wild Type if you:
Prefer natural, authentic appearance
Want cleanup crews that blend into the environment
Appreciate subtle colour variation over uniformity
Are interested in the species as it exists naturally
Want a more naturalistic aesthetic for display setups
Choose Colour Morphs if you:
Want visually striking, uniform colouration
Prefer easily visible cleanup crews
Enjoy the variety of selectively bred appearances
Want specific colours to match enclosure aesthetics
Care requirements are identical regardless of which you choose. The difference is purely aesthetic.
Other P. pruinosus options we stock:
Powder Blue – the classic blue-grey morph
Powder Orange – vibrant orange
Powder White – bright white
Oreo Crumble – black and white piebald
Orange Dalmatian – orange pied pattern
Rainbow Mix – multiple morphs combined
Who Are These Isopods For?
Wild Type Guadeloupe Powdered Isopods suit:
Keepers who appreciate natural, authentic appearance
Bioactive enthusiasts wanting inconspicuous cleanup crews
Naturalistic vivarium setups
Anyone interested in the species as it exists in the wild
Beginners wanting hardy, forgiving isopods
Those building large colonies economically
They might not suit:
Those wanting bright, eye-catching colours
Keepers who prefer uniform colony appearance
Anyone specifically wanting high-visibility cleanup crews
The wild type offers the same bulletproof hardiness and prolific breeding as the colour morphs, just with natural appearance rather than selectively bred colours.
