Building the tank
This is an aquatic species, so the habitat is measured in water rather than land.
Deep water needs at least 200 m². Deep water is the volume animals actually swim through — decorative shallow water does not count toward it.
Water type is Saltwater. Set it before the animal goes in; a saltwater species in the wrong water will not settle no matter how much space you give it.
Habitat temperature
Species it can share a habitat with
The Zoopedia lists 10 neutral companions. Neutral means no welfare penalty, but no shared enrichment bonus either — build to the largest space requirement of the group.
