Dwarf White Isopods (Trichorhina tomentosa)

Dwarf white isopods (Trichorhina tomentosa) are small terrestrial crustaceans commonly used as part of the detritivore community in bioactive vivaria. They inhabit the substrate and leaf litter, where they decompose organic waste such as decaying plant material, excess food, and animal waste, converting it into bioavailable nutrients and improving soil structure.

In dart frog vivaria, they are particularly important due to the consistently warm, humid conditions. Their high reproductive rate supports nutrient cycling and helps maintain sanitary conditions, while also providing a supplemental live food source for dart frogs and their tadpoles, contributing to overall ecosystem stability.
