Distribution and habitat preferences
Usually in schools along the edges of patch reefs adjacent to sandy lagoonal areas.
Can be found in most locations around the island.
Behaviour
This species is an active noctural feeder, and hunts for crustaceans and other invertebrates over the sandy lagoon floor and nearby reefs. Juveniles and small adults tend to form schools in shallow water, whereas the larger adults are solitary and found in deeper water. The Emperors are protogynous hermaphrodites, starting life as females and then changing sex to male at a larger size. Maximum age for this species is reported to be 19 years.
