Description
The resplendent pygmy angelfish has a body which is largely deep blue in colour. There is a yellow patch over the snout and yellow along the back and dorsal fin to the yellow caudal fin.[2] The dorsal fin contains 14 spines an 16 rays while the anal fin has 3 spines and 17 rats.[3] This species attains am maximum total length of 6 centimetres (2.4 in).[4]
Distribution
The resplendent pygmy angelfish is found in the South Atlantic Ocean where it is endemic to the waters around Ascension Island.[1]
Habitat and biology
The resplendent pygmy angelfish occur at depths between 15 and 40 metres (49 and 131 ft),[1] over rock and rubble substrates.[4] It feeds on algae or detritus. It is a protogynous hermaphrodite, like other members of the genus Centropyge, and the young fish are of indeterinate sex, become female at sexual maturity and if there is no male the dominant female changes sex to become male.[2] This sex change can be reversed, which takes a few weeks.[4]
Systematics
The resplendent pygmy angelfish was first formally described in 1975 by Hugh Roger Lubbock (1951-1981) and Richard D. Sankey.[5] The specific name resplendens means "resplendent", a reference to the beauty of its colour. Some authorities place this species in the subgenus Xiphypops.[6]
Utilisation
The resplendent pygmy angelfish is rare in the aquarium trade, although it has been successfully bred in captivity, albeit infrequently.[1]
