In its natural habitat, the Cloudy Damselfish is associated with branching corals on in- and offshore reefs, congregating in small schools to feed on plankton. At home, a 30-gallon or larger aquarium is suitable with plenty of hiding places. Due to its aggressive behavior as an adult, it will do well with other aggressive fish in a community tank. It will not harm invertebrates or disturb the tank setting.
It will need a diet of meaty items, herbivore preparations, and flaked foods.
