Range: Indo-West Pacific Ocean: Moluccas to Samoa, north to Izu Islands, and south to northwestern Australia and New Caledonia.

As to diet, plant material (its main food in the wild), e.g., flake foods, especially those containing Spirulina and Nori, along with most regular aquarium foods, e.g., live fortified brine shrimp and/or finely chopped various frozen or fresh meaty foods such as mysis, squid, fish flesh, shrimp, clam, etc., should be offered once or twice daily.
