Colony. Isopods are gregarious and are kept as a group – at least 5, better 10 to 20 animals to start. Only this one species per tub: faster-breeding isopods crowd out the small White Shark, and when food is short, larger species nibble freshly moulted animals.

A boldly white-and-grey Cubaris from the popular "Ducky" group. It grows and breeds slowly – patience is needed, but the animals are in demand. Keep it permanently damp with calcium on offer.
