Armadillidium vulgare 'T- Albino' (Tyrosinase-Negative) Isopods for Sale

Armadillidium vulgare 'T- Albino' is the "classical" true albino of the common pill bug — a striking, almost entirely white morph with a pale, ghostly appearance that stands out beautifully against dark naturalistic substrate. The "T-" stands for tyrosinase-negative: these isopods lack the functional enzyme needed to produce melanin pigment at all, which is why they appear clean white to pale cream, with at most barely-noticeable faint gold flecks. It's a genuinely eye-catching morph that pairs an unusual, sought-after look with the famously easy care of one of the hobby's most reliable species.

It's worth understanding the distinction between the two albino types, because they look very different. The T- (tyrosinase-negative) albino — this one — appears almost fully white, the true "classical" albino, and is generally the rarer and more prized of the two. The T+ (tyrosinase-positive) albino, by contrast, retains the ability to make non-black pigments and so shows warm shades of orange and gold. If you want the clean white look, the T- is the one; if you prefer warm orange-gold tones, the T+ is its sibling morph. Many keepers collect both.

Underneath the unusual colouration, this is the same bulletproof A. vulgare that anchors the beginner end of the hobby — hardy, adaptable, and forgiving. The species itself is native to Mediterranean Europe (and naturalised worldwide); the albino morphs were largely developed and popularised by North American hobbyists. Like all Armadillidium, the T- Albino conglobates — rolling into a tight, complete defensive ball when disturbed, the classic "roly-poly" behaviour, here on a striking white body.

What Makes T- Albino Isopods Special

Several factors make the T- Albino a properly worthwhile morph:

The clean white, ghostly appearance. This is the headline. As a true tyrosinase-negative albino, the T- shows an almost fully white to pale cream body with no dark pigment at all — a genuinely striking, luminous look that's quite different from the warm orange-gold T+ albino. Against dark substrate, a colony of white pill bugs is properly eye-catching.

The "classical" albino. The T- is the true albino in the genetic sense — a complete lack of melanin production. It's generally the rarer and more sought-after of the two A. vulgare albino types, which gives it a real collector's appeal.

Bulletproof hardiness. Underneath the unusual colouration, this is still A. vulgare — the species against which beginner isopods are measured. It tolerates a wide range of conditions and forgives the usual learning-curve mistakes, making it one of the easiest "fancy" morphs to keep.

Classic conglobation. Like all Armadillidium, the T- Albino rolls into a tight, complete ball when disturbed — the famous roly-poly behaviour. Watching a pure-white pill bug curl into a perfect sphere is genuinely charming.

Part of an albino pair. The T- and T+ albino together make a natural collector's pairing — the clean white T- alongside the warm orange-gold T+, both the same easy species. Many keepers want both for the contrast.

A reliable bioactive worker. As a hardy A. vulgare, the T- Albino is an effective cleanup-crew species and a calcium-rich snack for reptiles and amphibians — with the bonus of being far easier to spot against substrate than darker isopods.

How T- Albino Compares to Other A. vulgare Morphs

If you're choosing between A. vulgare morphs, here's how the T- Albino fits in:

• vs T+ Albino (A. vulgare): The key comparison — same species, two different albino genetics. T- is the tyrosinase-negative "classical" albino, almost fully white; T+ is the tyrosinase-positive albino showing warm orange and gold tones. T- is generally rarer; T+ is more colourful. Natural sibling morphs — many keepers collect both.
• vs Magic Potion (A. vulgare): Both are pale-toned A. vulgare morphs. Magic Potion shows a pale, marbled look; the T- Albino is the cleaner, whiter true albino. Same easy care, different pale aesthetics.
• vs 'Big Italy' (A. vulgare): Both are A. vulgare. Big Italy is the large Italian locality bred for size with classic colouration; the T- Albino is the size-typical white albino morph. Different selection priorities, same forgiving care.
• vs Snow White (P. laevis): Both are pale isopods, but different species and behaviour. Snow White is the smooth-bodied Porcellio laevis albino that does NOT roll; the T- Albino is the Armadillidium that DOES conglobate. Choose by whether you want a roller.

Setting Up the Enclosure

A 6–10 litre plastic container or glass terrarium with a secure lid suits a starter colony, with larger setups as the colony grows. A. vulgare is genuinely forgiving about enclosure choice. Provide enough space for the colony to move freely and spread out as it grows.

Drill ventilation holes on opposite sides for cross-ventilation, covered with fine mesh. Medium ventilation suits them. Provide plenty of hides — cork bark, leaf litter, moss, and wood pieces — so they can shelter or graze whenever they like. The white colouration shows particularly beautifully against dark naturalistic substrate. Keep the enclosure out of direct sunlight. Browse our accessories collection for appropriate enclosures, vents, and other essentials.

Substrate

Use a moisture-retentive, calcium-rich substrate:

• Organic topsoil base (pesticide-free) as the foundation
• Sphagnum moss and crushed leaf litter mixed throughout for moisture retention
• Crushed limestone or eggshells distributed throughout for calcium
• Flake soil mixed in for added nutrition
• Decaying hardwood pieces and rotting wood incorporated throughout

We recommend a topsoil and sphagnum-based mix rather than coco coir. Substrate depth: 5–8 cm for burrowing and security.

Top layer: Generous hardwood leaf litter — magnolia leaves, oak, and beech all work well — plus cork bark, moss, and decaying wood for hides. A sphagnum moss patch on the moist side completes the gradient.

Humidity and Temperature

Maintain humidity around 70–80% with a clear moisture gradient — keep one side of the enclosure damp with sphagnum moss and damp leaf litter, while the other side stays drier with leaf litter and bark cover. The isopods will move between zones according to their needs. Mist the enclosure regularly to stop it drying out too quickly, but never let it become waterlogged. Medium ventilation prevents stagnation while retaining humidity.

As one PostPods customer noted about following the website's care guidance, getting moisture right is the key to keeping isopods successfully — and A. vulgare makes this easy because it's so forgiving. The gradient still produces healthier, more visible colonies than uniform conditions either way.

Temperature should be 18–24°C — UK room temperature works year-round. They tolerate slight variation and a night drop is fine. Keep conditions reasonably stable and avoid sustained extremes.

Diet

T- Albino isopods are unfussy detritivores with broad appetites:

• Primary diet (always available): Hardwood leaf litter (oak, beech, magnolia), decaying rotting wood, dried plant matter, mosses
• Vegetables (1–2x weekly): Carrot, courgette, sweet potato, squash, leafy greens. Replace within 24–48 hours.
• Fruit (occasionally): Small amounts of soft fruit
• Protein (1x weekly): Fish flakes, dried shrimp, dried daphnia. Beneficial for breeding females. Browse our accessories collection for the full range of protein supplements.
• Calcium (essential — always available): Cuttlefish bone, crushed limestone, oyster shell, eggshells. Important for healthy moulting — provide a constant source.

Feeding approach: Maintain a base of leaf litter and decaying wood, supplementing with vegetables, occasional fruit, weekly protein, and a constant calcium source. Remove uneaten fresh foods within 24–48 hours to prevent mould.

Breeding

T- Albino isopods breed steadily and reliably once established under stable conditions — though, like all A. vulgare morphs, a settled colony builds at a satisfying rather than explosive rate.

Breeding basics:

• Females carry developing young in a marsupium (fluid-filled brood pouch) and release fully-formed live juveniles
• Females can store sperm and produce young even without recent mating
• The white albino colouration is genetic — a pure T- colony breeds true to the morph
• Multiple broods throughout a female's lifetime

For breeding success:

• Stable temperatures within range (20–23°C is ideal)
• A proper moisture gradient (70–80% with a damp side)
• Adequate calcium for breeding females
• Regular protein supplementation
• Plenty of cork bark and leaf-litter hides
• A larger starter group establishes faster and provides genetic diversity

Because the T- albino trait is genetic, keeping a pure colony reliably produces more striking white offspring — a satisfying morph to breed and watch develop.

Pair With Springtails

Add a thriving springtail culture to any T- Albino setup. Springtails handle mould and microbial growth at a scale isopods can't manage — particularly useful around protein foods and in the moist zone of the gradient. They coexist peacefully with the Albino and form a helpful cleanup partnership.

Who Should Buy T- Albino Isopods?

Ideal for:

• Keepers wanting a striking, clean-white true-albino pill bug
• Beginners wanting an easy, forgiving but unusual-looking morph
• Collectors building an albino pair (T- white + T+ orange-gold)
• Bioactive setup builders needing hardy, reliable cleanup crews
• Display enthusiasts who want an isopod that's easy to spot and conglobates
• Reptile and amphibian keepers wanting a calcium-rich cleanup species

Not ideal for:

• Keepers wanting the warm orange-gold look — choose the T+ Albino instead
• Those wanting an isopod that doesn't roll (Armadillidium conglobate — try Porcellio scaber for a non-roller)
• Heavily-planted bioactive setups where plant-nibbling is a concern

Realistic Expectations

It's white, not yellow. This is the genuine point of difference. The T- (tyrosinase-negative) albino is the clean white "classical" albino — if you're after warm orange-gold tones, that's the T+ albino, a different morph. Set expectations toward white-to-pale-cream with at most faint flecks.

They conglobate. Like all Armadillidium, the T- rolls into a complete defensive ball — the classic roly-poly behaviour, here on a white body.

They're properly easy. Care-identical to the common pill bug — among the most forgiving isopods in the hobby. A sensible choice even though the morph looks exotic.

They're a touch slower and shyer. The albino tends to move a little more slowly and spends time sheltered under leaf litter — calm, gentle, and most active at night.

It's a captive-bred morph. Albino A. vulgare are overwhelmingly a hobby-bred morph rather than something you'd find in the wild — you're keeping a genetic colour variant developed by breeders.
