海洋; 淡水; 半鹹淡水; 深度上下限 0 - 12 m (Ref. 86942). 24°C - 28°C (Ref. 1672); 31°N - 42°S, 19°E - 169°W
Indo-West Pacific: Red Sea and east coast of Africa south to the Breë River (Ref. 7293, 52193); also the Persian Gulf (Ref. 96822) to Samoa, north to the Yaeyamas, south to New Caledonia and Australia (Ref. 4959). Known from the freshwater tidal zone of the Mekong delta (Ref. 12693).
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 13.0  range ? - ? cm
Max length : 27.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 44894); common length : 12.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5450)
背棘 (總數): 7 - 8; 背的軟條 (總數): 27-31; 臀棘 3; 臀鰭軟條: 27 - 32.
Found in bays, mangrove estuaries, tidal creeks, and lower reaches of freshwater streams (Ref. 2847, 44894, 48636); occasionally in silty coastal reefs (Ref. 9710). It feeds on plankton and detritus (Ref. 5213, 44894). Commonly seen in large schools (Ref. 44894, 52193); small juveniles either solitary or in small aggregations (Ref. 48635). Usually only juveniles enter freshwater (Ref. 52193). Highly territorial (Ref. 9710). Caught with throw nets (Ref. 30573).
