The Potter's Dwarf Angel Fish is endemic to the Hawaiian Islands area, including the Johnston Atoll. The body is a brilliant orange, marbleized with pale to dark blue. The caudal portions of the dorsal and anal fins as well as the caudal fin are a dark blue-black.
The Potter's Dwarf Angel Fish requires a well-established aquarium with multiple hiding places and live rock for grazing on microalgae.
It may nip at soft corals and other sessile invertebrates in the reef aquarium.
It is hermaphroditic, difficult to breed, and there are no distinguishing characteristics to help differentiate males from females.
The Potter's Dwarf Angel Fish should be offered a variety of foods including marine algae, mysis or frozen shrimp, and chopped meaty foods.
