Indo-West Pacific: Red Sea and East Africa to Indonesia, north to the Ryukyu Islands and China, south to Australia, Melanesia and Samoa. Entered the eastern Mediterranean Sea through the Suez Canal.
Adults occur in coastal bays, harbors and deep lagoons, usually in some turbid plankton-rich waters. Form schools. Feed on phytoplankton (diatoms) and small zooplankton (cladocerans, ostracods, larval polychaetes, etc.) (Ref. 9684). Small groups were seen eating eggs of Cheilio inermis straight after spawning (Ref. 48637). Adult individuals feed on macroplankton such as larval shrimps and fish. Eggs and larvae are pelagic (Ref. 6769). Generally marketed fresh, frozen, canned, dried-salted, and smoked; also made into fish sauce (Ref. 9684).
