Found over shallow sandy bottoms, in the vicinity of river mouths. Enter estuaries and rivers (Ref. 1479, 11230, 44894, 48635), juveniles and adults are often found in freshwater (Ref. 4327). Adults in loose aggregations (Ref. 48635). Juveniles common in sandy intertidal areas; often in tidal pools. Minimum depth reported is 20 m (Ref. 12260). Found in schools (Ref. 9710). Omnivorous (Ref. 7300), feeding on fishes, insects, algae, and sand-dwelling invertebrates (Ref. 9710). Spawn in the sea and juveniles migrate into fresh water (Ref. 2847). Eggs are guarded and fanned by the male parent (Ref. 205). Produce sound (Ref. 9137). Caught on all types of inshore fishing gear including gill nets, traps, handlines, and bottom trawls and marketed fresh and dried-salted (Ref. 48274).
Eggs are guarded and fanned by the male parent (Ref. 205).
