Also known as the spangled emperor and sand bream, this is a species of emperor fish that occurs in the waters of East Africa to the southern parts of Japan. It also lives in Australian coastal waters, and has been recorded in the Red Sea, Persian Gulf and New Caledonia, where it is one of the major commercial fish.
This species inhabits both marine and brackish waters at depths of between 10 and 75 meters. It is a non-migratory species, and is found on coral and rocky reefs, seagrass beds, and mangrove swamps, as well as over sandy substrates. Juveniles may be found in large schools.
