Relevance to Humans and Ecosystems
Centropyge colini, the Cocos-Keeling angelfish, or Colin's angelfish is a small marine angelfish measuring up to 9cm, it is predominantly yellow with the upper quarter of its body being bright blue in colour. It inhabits reefs up to a depth of 100m in the Indo-west Pacific ocean, including around the Cocos (Keeling) Islands for which it is named. It is a rare and elusive species which spends much of its time hiding amongst rocks and rubble on reef top-offs. The fish move in harems of between 3 and 7 individuals, with one male and several females. If the male disappears the dominant female will change sex. Little is known about their ecology, and their natural diet is unknown. The fish is very rarely exported as part of the aquarium trade.
