There are some isopods that I hope will always be popular in the hobby. They are the ones that bring so many of us joy, be it because of their colours, or their behaviours. The isopod hobby includes a wide range of types of isopods, with new species and unique genus being discovered and introduced regularly. But I thought this time I’d look through my own collection and look at some of the rarer species that you may not have thought about keeping.
Cubaris Sp. Salmon Isopods
Hailing from the Carribean island of Martinque, these are a type of cubaris isopods, belonging to a visually striking genus known for their unique appearance. These isopods have all the visual appeal of cubaris sp but with the added layer of an ever changing colour. Starting out as a soft salmon colour these isopods darken in colour as they get older.
They’re surprisingly easy to keep, unlike some Cubaris sp. That can be a little more tricky.
Red Edge Isopods (Cubaris sp.)
Another Cubaris species with a cure appeal, Red Edge is another example of a new species within the cubaris genus. Red Edge has a deep colour for most of their body, and that striking red edge. They are prolific breeders for a cubaris species, although they do require warmer more humid environment than many other isopod species.
Camouflage Isopods Troglodillo Rotondatus
So often overlooked as they’re not as flashy as some other species, these are a more challenge, and in their own way rewarding, species. A seasonal breeder so if you get the environment right you will see your colony increasing.
Their native range stretches across China, and they will happily eat a wide variety of foods. Infact it is something I would recommend to make sure they have a broad diet.
Introduction to Isopods
Isopods, often affectionately called pill bugs or woodlice, are fascinating creatures that have become increasingly popular as low maintenance pets for terrariums and bioactive setups. With over 10,000 species discovered worldwide, isopods offer an incredible variety of shapes, sizes, and colors—making them a favorite among both beginners and seasoned hobbyists. From the instantly recognizable Rubber Ducky Isopods to the more elusive and rare species, these highly adaptable invertebrates can thrive in a wide range of habitats. Isopods are not only interesting to observe, but they also play a vital role in maintaining healthy ecosystems within your terrarium by breaking down organic matter and helping to keep the environment clean. Whether you’re interested in breeding, creating a bioactive setup, or simply enjoying the unique behaviors of these tiny creatures, isopods are a rewarding and endlessly fascinating addition to any collection.
Trachelipus Caucasius
I wasn’t sure if these deserved a place on a list of rarer species as in the wild they are found in a variety of areas around the Black Sea. But they’re not as popular as many species of isopod so that earned them a place.
A dark black body with an orange or red trim they are a nice looking isopod. Wild types of Trachelipus Caucasius typically have less of the red and orange coloration, while captive bred isopods have been selectively bred for more vibrant and striking colors. Some careful selective breeding has given us nice examples of the species that give you the eye-catching appeal of many of the species we keep and sell.
Armadillidium Ruffoi armadillidium species
We couldn’t have a list like this without including an Armadillidium species, and ruffoi suits the bill. That bit more unusual, they are originally from the mountains of Northern Italy, and do need a bit more effort to allow them to thrive. Compared to the more common Armadillidium vulgare, which is a popular member of the armadillidium isopods group and widely known as roly polies, Armadillidium ruffoi offers a unique experience for hobbyists. They are much slower to breed than the easier species, great if you don’t want to have too many isopods, or you enjoy a breeding challenge. Requiring a more humid enclosure and a more varied diet are the main two challenges, but as with most species these are easy enough to overcome.
To make up for it their carpice is almost artistic in looks, with various colours in a delicate contrast. Like other armadillidium isopods, they can roll into a ball as a defense mechanism against predators.
Porcellio Expansus
Porcellio expansus, sometimes called the Dragon or Beetlejuice Isopod, is a true showstopper among isopod species. Native to Spain, this species is renowned for its striking markings and impressive size, often reaching up to 1 inch in length—making it one of the largest isopods commonly kept in the hobby. Porcellio expansus is a prolific breeder, and with the right care, colonies can grow quickly. They thrive in terrariums that offer a strong moisture gradient, allowing them to choose between damp and dry areas as needed. Good ventilation is essential, much like with other Spanish Porcellio species, to keep them healthy and active. Their bold appearance and engaging behaviors make Porcellio expansus a standout choice for anyone looking to add a unique and eye-catching isopod species to their bioactive terrarium.
Cubaris Murina “Little Sea”
Cubaris murina, affectionately known as the Little Sea Isopod, is a small but captivating species that has won the hearts of many hobbyists. Native to tropical regions, these isopods are known for their unique appearance and lively activity within the terrarium. Despite their tiny size, Cubaris murina are prolific breeders and can quickly establish thriving colonies in bioactive terrariums. They do best in environments with high humidity and a varied diet, which helps them display their full range of behaviors and colors. Their active nature makes them a joy to watch, as they explore and interact with their surroundings. If you’re looking for a species that brings both charm and energy to your bioactive setup, Cubaris murina is an excellent choice.
Armadillidium Klugii “Montenegro”
Armadillidium klugii, commonly known as the Clown Isopod, is a vibrant and active species that stands out in any collection. Native to Europe, this armadillidium species is instantly recognizable thanks to its vivid orange-red skirts and distinctive white or yellow spots, giving it a truly unique appearance. Armadillidium klugii is an active species that enjoys burrowing in a deep substrate and benefits from a well-maintained humidity gradient within the terrarium. They thrive on a balanced diet and are known to be prolific breeders when their needs are met. Their lively behavior and striking coloration make them a favorite for hobbyists seeking a visually stunning and engaging isopod for their bioactive setup.
Conclusion: Choosing Your Unusual Isopod
With so many isopod species available, from the ever-popular Zebra Isopods to rare and exotic varieties, finding the perfect fit for your bioactive terrarium can be both exciting and a bit daunting. Each species has its own unique requirements—some, like the Dairy Cow Isopod, are prolific breeders that thrive in high humidity and enjoy a varied diet, while others, such as the Rubber Ducky, need more specialized care and attention to humidity levels. When selecting an isopod, it’s important to consider factors like humidity, temperature, and dietary needs to ensure your new pets will thrive. By researching the specific needs of each species and setting up your terrarium accordingly, you can create a healthy, vibrant environment for your isopods. Whether you’re just starting out or looking to add a rare species to your collection, isopods are fascinating creatures that bring life and interest to any bioactive setup.
