Indo-Pacific: Persian Gulf, Gulf of Oman, Pakistan, India, Sri Lanka, Burma, Andaman Islands, Thailand, Viet Nam, southern China, Malaysia, Indonesia, Philippines, Australia, New Guinea, Vanuatu and New Caledonia. Records for the Ryukyu and Ogasawara Islands could be based on strays (Ref. 9813).

Biology     Glossary (e.g. epibenthic)

Occurs in small schools of up to 10 individuals or so, in shallow coastal waters, brackish lagoons and rocky or coral reefs. Feeds on algae attached to the substrate and on floating algal fragments. Found resting in midwater at depths of 2 to 6 m when not feeding. Marketed fresh (Ref. 9813, 48637).
