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 indeterminate 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]
