Bicolor Angelfish, Centropyge bicolor (Bloch, 1787)
The Bicolor Angelfish is a tropical marine water fish, which is commonly seen singly, in pairs or in small aggregations. They inhabit rubbly areas in lagoons and on reef slopes.
Bicolor Angelfish are yellow anteriorly and blue posteriorly. There is a blue bar above the eyes and the caudal fin is yellow.
Angelfishes are related to the butterflyfishes (Family Chaetodontidae). The Angelfishes have a distinctive preopercular spine that is lacking in the butterflyfishes.
Bicolor Angelfish inhabit rubbly areas in lagoons and on reef slopes. They use crevices in the reef for shelter. The species is commonly seen singly, in pairs or in small aggregations.
It is found in depths from 3 m to 25 m.
It occurs in tropical marine waters of the Western Pacific, from Malaysia, north to Japan, south to Australia and east to Fiji.
In Australia it is known from the north-western coast of Western Australia around the tropical north of the country, and south to northern New South Wales.
