The isopods of the genus Cubaris are common in tropical Asia. They play an important role in the ecosystem as a decomposer. The Cubaris spp. are bred as pets due to their diversity in shape and color. This experiment examines the survival rates of Cubaris murina rearing in five different bedding, i.e., peat moss, facial tissues, sphagnum moss, polyester sponge, and dry leaves, to examine the trend of optimal bedding for rearing the isopod. Each bedding type contained ten isopods, and the data was collected daily for sixty days. The result revealed that the appropriate bedding with the highest survival rates were dry leaves, facial tissues, polyester sponges, peat moss, and sphagnum moss. Survival of isopods depends on factors such as humidity, air circulation, waste containment, and eating bedding material. Therefore, dry leaves are trend to the most optimal bedding.
