Cohabitation
Colony keeping; not with slow-growing isopods (it outcompetes them). These animals naturally live in groups. One colony per enclosure, and don’t merge colonies from different sources — that way you don’t introduce mites or pathogens and don’t mix colour morphs and breeding lines.

Notes

Very fast-growing and productive – an ideal feeder and clean-up isopod. It needs protein and must not dry out permanently.
