Centropyge fisheri
The Fisher's angelfish (Centropyge fisheri), known to tropical fish lovers as the orange angelfish, Fisher's dwarf angelfish, is endemic to Hawaii and Johnston Atoll in the central Pacific. These fish can be found near coral cliffs at depths of 10 to 75 m, where they feed on algae, crustaceans and small worms. They are among the smallest of the angelfish species, and have therefore become very popular among aquarists. Keeping the fish is recommended for aquarists with aquarium care experience.
Although Centropyge fisheri is closely related to Centropyge flavicauda and was crossed with them, the Fisher's Angels have an orange-brown coloration with golden sheen, with black mottling on the upper body and fine bright blue markings on the outer edges of the anal, ventral, dorsal and caudal fins. There is a black spot just above the pectoral fins. Sexual differences are poorly expressed, with males being slightly larger than females. Fish reach a size of 7 cm.
Like all angelfish, Centropyge fisheri are all female when reaching sexual maturity. When kept in a group, the dominant individual changes sex and becomes a male. This usually occurs within a few days to a few weeks. To get a pair just put in an aquarium two individuals of different sizes, and a couple of months, one of the fish will become a male.
The Centropyge fisheri is a very interesting and curious fish. They can easily be kept in a community tank with other peace-loving and size-matched fish. They should be kept in an aquarium of at least 150 liters with plenty of live rock and caves in which they can swim and hide in case of danger. Fischer's angelfish may show signs of aggression towards their own kind.
Water parameters: temperature 20-26° C, hardness dH 8-12°, acidity pH 8,0-8,5, salinity 1.020-1,026. Need filtration, aeration and weekly replacement of 1/5 of the aquarium water with fresh. With proper water quality fish are highly immune to disease.
The diets of fish in nature consist of algae, small crustaceans and worms. In an aquarium, they are fed with seaweed, spirulina, artemia nauplii and sponges. Preferably give food in small portions several times a day.
Reproduction
Centropyge fisheri do not propagate under aquarium conditions.
The Centropyge fisheri has a lifespan of about 5-7 years in an aquarium.
