Oniscus Asellus "Mardi Gras Dalmatian"
$5.00
Oniscus Asellus "Mardi Gras" is one of those few isopods you must see in person to truly appreciate their diverse black and white patterns with a vibrant splotch or two of lemon yellow. This morph was isolated and refined through selective breeding of individuals exhibiting this unique dalmatian pigmentation. It is a species worth adding to your collection and at this time is still highly sought after.
Oniscus Asellus is a species that does have some unique care needs and tends to be less forgiving if their requirements are not correct and consistent. A starter group of 10-15 individuals can be kept in a small enclosure like a 6qt storage bin or small glass tank. Natural botanicals are a great way to decorate your enclosure in a way that mimics the isopods natural habitat. They are also fond of concave cork bark which they can often be found huddled up in small groups. These isopods (wild types) naturally occur in northern parts of the USA and up into Canada. As such, they thrive in cooler temperatures which sets them apart from the vast majority of other terrestrial isopods. 65-72F is ideal though they can tolerate slightly warmer ranges. Wide swings in temperature are generally not tolerated well and could result in a crash, so ensure your bin is in a location where fluctuations will be minimal. They also are noted to do better with a minimal moisture gradient leaning more towards the moist side. It is recommended to keep some area drier, but this needs not be more than 25% of the available space.
Isopods have evolved to be detrivores with their primary diet being decayed organic matter. In the wild this is largely things like soft rotting wood and dried leaf litter along with any other deceased plant or animal they might stumble upon. Supplemental vegetables items like carrots, squash, potatoes and similar are readily accepted. Commercial powdered isopod diets like Repashy Morning Wood are also highly recommended. A serving or two of protein each week is appreciated and devoured. Fish pellets, freeze dried shrimp or minnows are just a few types these isopods will eat without hesitation.
Oniscus Asellus is most active at night. You may see a few out and about during the day, but the majority tend to be reclusive until they lights are out. They make an ideal clean up crew if used in a bioactive as they do like to burrow and eat the substrate to some degree. This isopod is not a prolific breeder so understand that building a sizeable culture will take time and patience. Though this gorgeous isopod does have some potentially challenging care needs, it is worth keeping if it's required parameters can be maintained without large deviations. See our full care guide for Oniscus Asellus which expands deeper into all aspects of keeping and breeding this designer isopod species.

Cylisticus Convexus Ukraine Pied Isopod
$1.75
Cylisticus Convexus originates from Europe but now can be found on nearly every major continent with human habitation. They're a very adaptable species able to thrive in a multitude of climates ranging from semi arid to semi tropical. They're sometimes referred to as the "Curly Isopod" or "Teardrop Isopod" due to the fact when they roll into the classic defensive ball, it's only does so partially creating more of an oval shape than a sphere like many other isopod species. This particular type dubbed the "Ukraine Pied", originates from individuals collected in Ukraine showing the black and white dalmatian pattern. These original specimens were then further refined with selective breeding as to have a visually appealing amount of contrast.
This isopod is on par with the well known powder blue or powder orange in terms of overall general care. They are a very easy species to keep and can become quite prolific once well established. They tend to burrow into the substrate to some degree so some additional depth is of benefit. They are nocturnal and will quickly scurry to hide or burrow if exposed to bright lighting. But they are truly enjoyable to observe at night as they will come out in force with no reservations moving all about their enclosure foraging and searching for food.
A 6 quart gasket sealed storage bin or small glass aquarium is sufficient for a small starter culture. Standard or bioactive enclosures can be enhanced with natural botanical items to simulate the isopods habitat in the wild. This helps them feel secure which in turn promotes their natural processes like eating and breeding. Average room temperature in the low to mid 70sF will suit them just fine. Around one half to one third of the enclosure should have damp (not wet) sphagnum moss with the remainder being a bit on the dry side. This species will do fine in almost any type of environmental set up so long as it isn't completely over saturated or too arid with little to no moisture. We find an average moisture gradient works well with this species. A few pieces of cork bark strategically placed over some of the moist side will help retain the humidity levels and reduce the frequency of watering needed to maintain a proper moisture gradient.
Isopods are detritivores. Their primary diet in nature is leaf litter and decayed wood. Both of these should always be available in abundance. They will also happily consume any other decomposing organic plant or animal matter they come across. As such it is vital to supplement your isopods with other food sources on a semi regular basis. They enjoy food options like squash, radishes, carrots and other veggies along with commercial isopod powdered food like Repashy. Ukraine Pied isopods are fond of protein in their diets which can be things like freeze dried minnows, shrimp, fish pellets, dried insects and other protein based food sources. They do have an impressive feeding response when offered such items. Almost like a swarm of piranhas, they will cluster all over the food source and devour it quickly. But this is mostly only at night or in low light settings. Be sure to feed these on the drier side as they can spoil quickly in humid environments and attract unwanted pestsCylisticus Convexus Ukraine Pied is a great choice for clean up crew in a wide variety of environmental enclosure types. They are very good and quickly breaking down any type of decaying plant or organic materials. They're also a great first isopod if you're new to the hobby. Just know they aren't the best display type unless you are a night person as well. They won't be seen much during the daylight hours. So long as you ensure they don't dry out and offer them a reasonable amount of supplemental food items, they will multiply and flourish without any needed extended efforts on your behalf.

Trachelipus Caucasius Isopod
$2.75
Trachelipus Caucasius is an odd ball isopod not quite known and popular as other species. None the less they are more than deserving of some love and recognition. This unique crustacean originates from Georgia (the country), Turkey and select areas around the black sea. They are on the larger size with some reaching close to 1 inch! They are a beginner friendly species and are relatively easy to keep. They colored edging ranges from orange to peach or a very light pink on some. These colors contrast nicely with their dark base color giving them visual appeal when they're out and about.
For housing they need a bit more space to accommodate their larger body sizes. A 12 quart sterilite gasket sealed bin or medium sized glass tank measuring at least 18-24 long by 12 or more inches wide is ideal for a starter colony with some room to grow. Enclosures can be enhanced with natural botanical items to simulate the isopods habitat in the wild. This helps them feel secure which in turn promotes their natural processes like eating and breeding. A good temperature range for this species is 72-80F leaning more towards the warmer end if possible. Trachelipus Caucasius is somewhat dry tolerant but as always ensure they have some access to moisture so they can rehydrate as needed. A standard moisture gradient comparable to Vulgare or Klugii isopods will suit them just fine. A few pieces of cork bark strategically placed over different parts of the enclosure will help retain the humidity levels and reduce the frequency of watering needed to maintain a proper moisture gradient while also providing beneficial micro climates.

They enjoy food options like squash, radishes, carrots and other veggies along with commercial isopod powdered food like Repashy. They also do appreciate some protein occasionally which can be things like freeze dried minnows, shrimp, fish pellets, dried insects and other protein based food sources. Be sure to feed these on the drier side as they can spoil quickly in humid environments and attract unwanted pests.
Trachelipus Caucasius is a fun unique isopod that serves well as clean up crew or beginner option if you're new to isopods. They have fascinating color contrast and get on the larger size for terrestrial isopods. They're not overly sensitive so a small amount of neglect will typically not be detrimental. This less than mainstream isopod species can make a great pet or terrarium addition for your needs!
