Bellus Angelfish are best housed as a male-female pair or small harem of one male and few females in a 125-gallon or larger aquarium, and are ideal candidates for the deep-water reef aquarium. Acclimation will be facilitated by a dimly-lit tank, but these fishes seem to adapt well to the intense lighting in most modern reef aquariums. The tank should have multiple hiding places and live rock for grazing. Do not keep two males in the same tank as fighting will ensue.
The Bellus Angelfish are hermaphroditic and have the ability to change sex from female to male, and males can even revert back to female if no females are present in the aquarium. They are difficult to breed, but many seasoned veteran aquarists have successfully observed these fishes spawning on a regular basis in very large home aquariums.
A varied diet of meaty foods such as vitamin enriched frozen brine shrimp, plus spirulina, marine algae, high-quality angelfish preparations, mysis or frozen shrimp, and other meaty items will provide good nutrition.
