Cohabitation
Colony. Isopods are gregarious; animals of different sizes live mixed together in the group – 5 to 10 animals to start with plenty of flat-stacked bark, so that males can get away from irritated females. Only this one species per tub: it breeds slowly and is crowded out by more prolific isopods.

Notes

Europe's largest terrestrial isopod, to be kept markedly drier than tropical species – waterlogging kills the colony. It grows slowly and breeds sparingly.
