Marine Fish

The Potter's Angelfish, or Potter's Pygmy Angelfish, 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 Angelfish requires at least a 30 gallon, well-established tank with multiple hiding places and live rock for grazing on microalgae. It may attack 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 Angelfish should be offered a variety of foods including Spirulina, marine algae, high-quality angelfish preparations, mysid or frozen shrimp, and other meaty items.
