Description
editThe Cocos-Keeling angelfish is mainly lemon-yellow in colour with a wide blue stripe from the nape along the back to the middle of the dorsal fin. There is a thin purplish ring around the eye.[2] The dorsal fin contains 14 spines and 16-17 soft rays while the anal fin has 3 spines and 17 soft rays. This species attains a maximum total length of 9 centimetres (3.5 in).[3]
Distribution
editThe Cocos-Keeling angelfish has been recorded from a scattering of sites in the Indo-West Pacific. These include the Spratly Islands, Palau, Papua New Guinea, Indonesia, Marshall Islands, Cocos Keeling Islands, Fiji and Guam, with an unconfirmed report from the Ogasawara Islands off Japan.[1]
Habitat and biology
editThe Cocos-Keeling angelfish is found at depths between 20 and 100 metres (66 and 328 ft).[1] It is a shy and secretive species which lives in crevices and caves in deep reef drop offs. It is found in groups which consist of a male and a harem of 2-6 females.[3] The male is replaced by the most dominant female if he disappears. Very little is known about the diet of this species.[2]
Systematics
editThe Cocos-Keeling angelfish was first formally described in 1974 by William F. Smith-Vaniz and Ernest J. Randall (1924-2020) with the type locality given as Turks Reef in the Cocos-Keeling Islands.[4] Some authorities place this species in the subgenus Centropyge.
Etymology
editThe specific name honours the biologist Patrick L. Colin who helped collect the type.[5]
Utlisation
editThe Cocos-Keeling angelfish rarely appears in the aquarium trade.[3]
