Description

The Moorish idol (Zanclus cornutus) is an unmistakable reef fish of the family Zanclidae from the Indian and Pacific Oceans. The species has a tall, strongly laterally compressed, disc-shaped body with broad black, white and yellow vertical bands, a long, whip-like dorsal-fin ray and a tubular snout. It reaches about 23 cm and inhabits both turbid inner lagoons and reef flats and clear seaward rocky and coral reefs. It is usually found alone or in small groups. The diet consists mainly of sponges and small bottom invertebrates, which it picks from crevices with its narrow snout. Owing to this specialised diet it is difficult to keep in the aquarium.
