The Moorish idol (Zanclus cornutus) is a distinctive coral reef fish that’s found throughout the tropical and subtropical regions of the Indo-Pacific. It’s usually seen singly or in pairs and feeds on small encrusting animals like sponges and sea squirts. Moorish idol larvae float in the plankton for 100 days before settling on the reef – a record for reef fish. This is the reason for its wide distribution and distinctive coloring that doesn’t vary between regions.
The Moorish idol is one of the most popular home aquarium fish but it is very hard to keep. Most fish don’t survive the year 😦
