Found on rocky substrata from near shore to at least 50 m. It is an aggressive territorial species that may occupy a particular cave for life. Small individuals feed on crabs and small fishes. Sexual transition reported to occur at 100-110 cm (Ref. 6787). Large individuals are often attracted by divers (Ref. 9710). An esteemed food fish avidly sought by anglers and spear fishermen.
