It makes a good nano reef tank fish considering its reef compatibility and small size. However, as a community fish, it should only be housed with larger fish or similar sized fish that have equally aggressive temperaments. It cannot be mixed with other members of its own species. It should be fed both meaty and herbivorous preparations and can eat live, frozen, pellet or flake foods.
