Care
The beautiful but cryptic Potter's Angelfish is endemic to Hawaiian reefs, where it is usually found amongst the abundant stony Porites corals. It is essential that this shy, delicate fish is placed into a spacious mature system with plenty of live rock and no aggressive tankmates if it is to do well. It should also be the only angelfish present in the tank, unless a mated pair is acquired. Ideally, the tank will be both long and wide to allow for plenty of aquascaping with living rock (ensure there is an abundance of dark shady crevices) and to accommodate the growth of stony coral cover. A larger tank should also ensure that the fish is more unlikely to continually pick at any one particular sessile invertebrate and cause irreparable damage. Powerful filtration is a must, as is decent water movement /high level of oxygenation. As stated before, tankmates should be of a placid nature and should not be a direct food competitor for the Potter's Angelfish. As microalgae makes up a large component of the diet, avoid other grazers of this foodstuff.
Feeding
In the wild, the Potter's Angelfish is reported to feed on algae and detritus. These fish will take prepared foods in the home aquarium, but these are no substitute for a long-established mature system with natural grazing opportunities on and amongst the living rock. Supplementary foodstuffs should be varied and fed in small amounts several times per day: Spirulina & marine algae, meaty fare such as vitamin/Spirulina-enriched brineshrimp, Mysis shrimp, special sponge-based Angelfish preparations, zooplankton, and finely chopped krill/squid/cockle/mussel.
Breeding
This egg-scattering species has not been bred in the home aquarium. In the wild, all Potter's Angelfish start off as females, and the dominant fish in a group becomes a male (protogynous hermaphroditism).
