Cubaris Sp. Happy Nun is a smaller Cubaris native to Thailand averaging about 1/2 inch in size. What they lack in size, they make up for in color! Their base can range from dark gray to a medium beige. Most have intricate translucent bronze markings though the amount and intensity varies from individual to individual. All of this is outlined with a creamy white edging which overall gives them a nice contrast. These isopods move quite fast compared to most others and quickly dart away if exposed or frightened. They are not overly difficult to keep, but as Cubaris they do have a few extra requirements beyond typical isopod 101.
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 will suit them just fine but keep in mind they are native to tropical to sub tropical areas so so do not let it get too cool. A good temperature range for Happy Nun is 74-80F leaning more towards the warmer end if possible. Happy Nuns do not need a pronounced moisture gradient like most other isopods. A small gradient is fine, but a consistent lightly damp (not wet) enclosure is ideal. They will not fare well if allowed to get any level of dry. A 65%-75% humidity level without large deviations will keep them in their comfort zone. 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. The substrate should at least 4-6 inches to allow for burrowing and extra moisture retention. This species tends to enjoy bark flats slightly off or above the substrate so offer several hides with various levels of clearance from the substrate ranging from very close to a few inches so they can self regulate as needed. Do allow some ventilation so the air and substrate does not become stagnant.
Isopods are detritivores. Their primary diet in nature is dried leaf litter and rotting 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 Morning Wood. They also need some occasional protein in their diets 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. Sharing the common theme of most other Cubaris isopods Happy Nuns are noted to be fond of limestone, mirroring the caves and rocky areas they naturally occur. This holds true for our breeding colony as they quickly devour calcium sources like cuttle bone when offered. Texas Holy Rock (in small chunks) is a favorite as well.
Happy nuns once established will produce medium sized broods on a fairly regular basis. They are an active isopod and will often be seen moving about, more so in the twilight hours and night times. Their variable color patterns and overall ease of care make them a great choice for the sub tropical to tropical terrarium. They are outstanding bio janitors and will work diligently to minimize plant and organic waste materials.
