Seychelles Butterflyfish

The Seychelles butterflyfish (Chaetodon madagaskariensis) is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found in the Indian Ocean from eastern Africa (as far south as Port Elizabeth in South Africa) east to Cocos-Keeling Islands and Christmas Island, north to Sri Lanka. The Seychelles butterflyfish is found in areas of rich coral growth on seaward reefs, at 10–40 m depth.

It grows to a maximum of 13 cm (more than 5 in) long. The body color is silver at the head, becoming white towards the tail, with a triangular orange patch covering the posterior and the caudal peduncle. There are a series of dark grey chevron lines on the sides of the body, partly broken into spots. Between the eyes and the start of the dorsal fin there is a black patch rimmed with white. The base of the caudal fin is white, followed by an orange patch and a white rim.
