Inhabits shallow rocky areas, often in pools of the intertidal zone (Ref. 2798). Occurs mostly in coastal areas. Also found in estuaries, tidal zones and often ascending into freshwater streams; smaller species live between branches of corals where they exploit several crustacean groups. Feeds on crustaceans, fish and algae (Ref. 92840). Sometimes seen as fresh catches at markets (Ref. 12693).
