None (a native species; a cooler overwintering is possible but not essential)
Cohabitation
Colony. The animals naturally form dense aggregations and are kept as a group – 10 to 20 animals to start. Only one species and one colour morph per tub: morphs interbreed back within two to three generations, and as a very prolific species it crowds out slower isopods.

Notes

The classic clean-up and feeder isopod for bioactive terrariums; crepuscular and nocturnal, very robust and undemanding. Numerous cultivated colour forms (orange, dalmatian, koi). A gill breather – it needs permanently damp areas.
