Rubber Ducky Isopod, Cubaris Sp.

The rubber ducky isopod, Cubaris sp., is a famous and popular pet isopod that has caught the attention of many people, especially those who are enthusiastic about exotic pets. Originating from Thailand, these isopods have become particularly popular in recent years due to their adorable appearance, resembling a rubber ducky with a little orange duck-beak. They have a dark exoskeleton with a duckling-yellow “head” and “tail,” which give them their look. They’re pretty small, generally measuring less than an inch in length, making them a manageable size for enthusiasts looking to keep them as pets. These isopods thrive in a humid environment with temperatures ranging between 70-80°F (21-27°C). Like all isopods, rubber ducky isopods are detritivores, meaning they feed on decaying organic matter. This makes them beneficial for breaking down waste in their habitat. They are relatively social creatures, often seen congregating with other isopods. While they are mainly nocturnal, it’s not uncommon to spot them scurrying about during daylight hours in search of food. Rubber ducky isopods are relatively low-maintenance pets, but they do require a specific set-up to mimic their natural habitat in natural limestone caves. A mix of moist soil and leaf litter is generally recommended, along with regular misting to maintain humidity levels. When kept in captivity, they can be fed a variety of foods including decaying leaves, wood, and treats like fruits and vegetables. They’ll require a source of calcium such as cuttlebone, although limestone is recommended for this species. Keepers have found benefit in using bat droppings as part of their substrate for a truly prolific colony, as bats live in the limestone caves they inhabit. Cubaris Sp. ‘Rubber ducky’ are a popular addition to any isopod collection or as a standalone pet. Their unique appearance have made them exceptionally popular in exotic pet circles.
