Adults occur on rocky bottoms and in the vicinity of coral reefs (Ref. 55, 57393, 81653). Young are frequently encountered in coastal waters, particularly estuaries and sometimes in lower courses of rivers (Ref. 2683, 57393, 81653). Voracious predator (Ref. 57393), feeds mainly on fishes and bottom-dwelling invertebrates (Ref. 55). Size of juveniles ranges from 7.90 to 19.99 cm in length (Ref. 111357).
生活於岩石底部與在鄰近珊瑚礁。 幼魚時常在沿岸水域被見到, 特別地河口與有時在河中.(參考文獻 2683) 主要吃魚與底棲無脊椎動物。
