Centropyge fisheri (Snyder, 1904)
Centropyge fisheri is a benthopelagic species found on reefs, on coral bottoms of channels and over reef slopes, and in areas with rubble bottoms. Often in small loose groups on inner reefs. FishBase indicates that Centropyge fisheri is herbivorous.
Centropyge fisheri can be distinguished from other members of the species by its almost transparent (except for a dark anterior part of the dorsal and ventral margins), slightly whitish to yellowish caudal fin, in contrast to the dark blue caudal fin of Centropyge argi and Centropyge aurantonotus, or by its bright yellow to orange caudal fin with a dark blue outer margin in Centropyge resplendens.
In the past, Centropyge fisheri was very difficult to obtain, but today it can be found on the stock lists from time to time. However, it is not a fish that is regularly found in the dealers' aquariums. In addition, it is almost only offered in the aquarium trade under the synonym Centropyge flavicauda.
It used to be assumed that it is endemic to Hawaiii, but this is not the case according to confirmations from some experts such as Jack Randall or Richard Pyle. We therefore adhere to the information from FishBase here. However, the animals from the Hawaiii region differ in coloration from the animals from the remaining regions of origin.
The author Frank Schneidwind describes it as a difficult species to keep, because it is a food specialist. However, F. Schneidewind also writes that this species has spawned in the aquarium. It usually occurs at depths below 30 meters. A photo was kindly provided by Keoki Stender, from http://www.coralreefnetwork.com.
A bidirectional sex-reversal (from female to male / from male to female) has been confirmed for this species.
The sex of this angelfish can be easily distinguished: the males have a blue-edged fin margin, which the females do not.
Sex and mating
The dwarf emperors are female from birth. If two fish are put together, then the more dominant animal becomes the male (=protogyne hermaphrodite).
It is best to put two fish of different sizes at the same time. If a fish is already present, then the new fish should be either much smaller or larger. If a larger fish is added, which would be an advantage, then the internal aggression is not as pronounced. The difference in size can be an advantage when pairing up, but there will still be scuffles until the sexing is complete.
