Indo-West Pacific: known with certainty from the Red Sea and the northwestern Indian Ocean. Also reported from Australia, Polynesia and Japan and rarely in the Mekong delta (Ref. 12693).
西印度洋: 確定知道的從紅海與在西北部的印度洋。 一個近親的形式出現於菲律賓與泰國灣中。 一般對於這個魚種的分布區認定過寬，由於將分佈區重疊的相似種誤鑑為該魚種。 也記錄自澳洲, 玻利尼西亞與日本而且極少在湄公河三角州。 (參考文獻 12693)

A marine species often found in estuaries, but rarely enters freshwater. Typically euryhaline (Ref. 3876). Reported to occasionally ascend into fresh water (Ref. 12693). Recorded at temperatures ranging from 26-29°C. Feeds mainly on crabs, prawns, mantis shrimps (Squilla species) but also on fishes and mollusks. An important food fish. Marketed mostly fresh; often dried.

Incubates eggs in the mouth. The fry continue to take refuge in the mouths of the male fish for the first 2 months and once they leave, the males start to eat avidly and may consume their ouwn young.西印度洋: 確定知道的從紅海與在西北部的印度洋。 一個近親的形式出現於菲律賓與泰國灣中。 一般對於這個魚種的分布區認定過寬，由於將分佈區重疊的相似種誤鑑為該魚種。 也記錄自澳洲, 玻利尼西亞與日本而且極少在湄公河三角州。 (參考文獻 12693)
