Cohabitation
Colony. Isopods are gregarious and are kept as a group – about 10 animals to start, with plenty of flat-stacked bark as hides. Only this one species per tub: other species crowd it out or, when protein is short, get nibbled as freshly moulted animals.

Notes

A "skeleton" pattern. The most important keeping mistake is too much wet and poor ventilation – it needs a dry, very airy setup with just one damp corner. Calcium for moulting. Not suitable for the standard damp isopod box.
