Heniochus acuminatus - Chaetodon acuminatus
Widespread Indo-West Pacific, ranging to well into sub-tropical zones. Various reef habitats from rocky estuaries to deep coastal and inner reef habitats, less common on outer reefs. Usually found in rocky or rubble zones. Adults normally swim in pairs or small groups close to reefs. Juveniles singly or in small groups in estuaries and harbours. Distinguished from the very similar Heniochus diphreutes by the longer snout, its more elongated shape, and having a longer and more angular anal fin when adult. Juveniles lack the white posterior area behind the last black band and this is all yellow instead, blending in with the colour of the soft dorsal and caudal fin. Length to 25cm,
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.
