Form schools. They occur frequently near the bottom, mostly in depths of 30 to 50 m. Also pelagic and found near the surface at times. Entering brackish-water lagoons and estuaries (Ref. 57392). Feed on small fish and invertebrates (Ref. 3195). Spawning grounds are located in shallow waters (Ref. 57055). Eggs are pelagic (Ref. 4233).
