The Moorish idol (Zanclus cornutus) is a species of marine

ray-finned fish belonging to the family Zanclidae. It is the only member of the monospecific genus Zanclus and the only extant species within the Zanclidae. This species is found on reefs in the Indo-Pacific
region.

Taxonomy

The Moorish idol was first formally

caudal peduncle is a clear difference between this species and the surgeonfishes. However, Eozanclus brevirostris, an extinct species from the Eocene that is a close relative of the Moorish idol seems to be intermediate between the surgeonfishes and the Moorish idol.[7]

Etymology

Moorish idol's unusual name was apparently given to it because in some areas of south-east Asia fishermen have respect for these fishes releasing them when caught and honouring them with a bow after their release.

Ancient Greek word zanklon, meaning "sickle", and is an allusion to the long curved dorsal fin. The specific name, cornutus, means "horned", and refers to the small bony protuberances over the eyes.[10]

Description

The Moorish idol's body is highly compressed and disc-like in shape with a tube-like snout and small bony protruberances above the eyes in adults. The mouth is small and has many long, bristle like teeth.

caudal fin is black with a white margin.[7]

Distribution and habitat

The Moorish idol has a wide range in the Indian and Pacific Oceans. They are found from the eastern coast of Africa between Somalia and South Africa east to

benthopelagic
fish which is found at depths between 3 and 182 m (9.8 and 597.1 ft) in turbid lagoons, over reef flats and in the clear water on rocky and coral reefs.

Biology

Moorish idols feed on

benthic invertebrates.[12] They are normally found in small groups of 2 or 3 individuals but they can also be solitary or gather in large schools. They have a long pelagic larval stage and this is why they are so widespread and geographically uniform.[2] These fishes are pelagic spawners the males and females release sperm and eggs into the water and the eggs drift away on the current following fertilisation.[12]

In the aquarium

Moorish idols are notoriously difficult to maintain in captivity. They require large tanks, often exceeding 380 L (84 imp gal; 100 US gal),[13] are voracious eaters, and can become destructive.[13]

Some aquarists prefer to keep substitute species that look very similar to the Moorish idol. These substitutes are all butterflyfishes of the genus

false Moorish idol, H. diphreutes.[citation needed
]

Moorish idols typically are very picky eaters. They will either eat no food and perish, or eat everything all at once.[13]
