The Pygmy Angelfish requires a 55 gallon or larger tank with numerous hiding places and live rock for grazing on microalgae. It may nip at large-polyped Stony Corals and clam mantles.

The Pygmy Angelfish is an aggressive little angelfish, so it is best to never have more than one male per tank, since they may fight to the death. A breeding pair may be kept, and the Pygmy Angelfish has been bred in an Aquarium with success.

The diet of the Pygmy Angelfish should include Spirulina , marine algae, high-quality angelfish preparations, Mysis or frozen shrimp, and other meaty items. Feed three times daily.
