Isopod Housing tools: what they help with

These calculators size your isopod's living space: the minimum and recommended dimensions, how much bedding or substrate to buy and what fits in the space you have. Too little space is one of the most common welfare problems in pets. The right size gives a isopod room to move, rest and behave normally.

What to know about housing and enclosure size for isopods

Isopods are clean-up crew invertebrates that thrive in a bin with damp substrate, leaf litter and a piece of cuttlebone for calcium. They need a moisture gradient so they can pick their own humidity. Target humidity is around 70-85%.

Treat the minimum as the floor, not the goal. Bigger is almost always better, especially for active or social species.
