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.
The giant moray (Gymnothorax javanicus) is a species of moray eel and a species of marine fish in the family Muraenidae. In terms of body mass, it is the largest moray eel. It is widespread in the Indo-Pacific region living in lagoons and on the outer slopes of coral reefs, during the day it sits sheltered in crevices. The giant moray is carnivorous, it leaves its lair at night to actively hunt its prey along the reef. It mainly feeds on fish and occasionally on crustaceans. Moray eels' habit of keeping their mouth open is sometimes misinterpreted as a threatening posture but they are kind of shy and they would rather flee than fight.
