The Moorish idol (Zanclus cornutus), is a marine fish species, the sole extant representative of the family in order Perciformes. A common inhabitant of tropical to subtropical reefs and lagoons, the Moorish idol is notable for its wide distribution throughout the Indo-Pacific. It is considered one of the most beautiful coral reef fishes and a Moorish idol named Gill was one of Nemo's tank-mates.
They have a habit of snacking on corals and sponges, as seen here.
