Building the tank

This is an aquatic species, so the habitat is measured in water rather than land.

Deep water needs at least 50 m². Deep water is the volume animals actually swim through — decorative shallow water does not count toward it.

Water type is Freshwater. Set it before the animal goes in; a freshwater species in the wrong water will not settle no matter how much space you give it.

Species it can share a habitat with

The Zoopedia lists 1 neutral companions. Neutral means no welfare penalty, but no shared enrichment bonus either — build to the largest space requirement of the group.
