They are generally hardy, adaptable, and well suited to beginners. If you're new, our isopod care guide explains the fundamentals of keeping healthy colonies.

Bark shelter zone: security and hiding
Moss humidity pocket: controlled moisture
Open substrate zone: movement and exploration
Calcium source area: supports moulting

You can build a suitable setup using materials from our isopod supplies collection.

Humidity and Moisture Requirements
