Widespread in the tropical Indian Ocean, ranging east to Sumatra. Previously reported from the Indian Ocean and western Indonesian region as Chaetodon unimaculatus, its Pacific sibling. Coral reef flats to deep slopes. Adults usually swim in pairs, sometimes forming small groups. Identified by its bright yellow body with rounded black spot on the sides. Similar to C.unimaculatus, but apart from being mostly yellow, the black band over the head is about pupil-width. Juveniles have a white-edged, black ocellus that is not vertically elongated like that in C.unimaculatus. Length to 20cm.
The members of the family Chaetodontidae, popularly know as butterflyfishes, coralfishes and bannerfishes. Most species of butterflyfish live in the warm tropical seas of the Indo-Pacific (about 90%) with the remainder in the Atlantic. Only a few species are found in subtropical waters, bordering onto subtemperate zones. The butterflyfish have a highly compressed body in which the back is raised , forming an elongate-oval to near circular shape in some; a small protactible mouth with brush-like teeth in the jaws; a continuous dorsal fin with strong and sharp spines in the anterior section, followed by a large-surface soft part; an anal fin mirroring the soft part of the dorsal fin , headed by 3-5 strong spines, of which the 2nd is often greatly enlarged.
