When a sense has developed, one can venture into more sensitive species of isopods. By “sense” I mean that you can see right away whether your animals are missing something or not. If there is a dead woodlouse in the terrarium, which can happen again and again, you can see why it died and possibly adjust the keeping a bit.

Such abilities come with time. If you think you’re experienced enough, you can get one of the species listed below. In general, ventilation should be generous and many species are sensitive to high humidity.
