May be seen in a variety of habitats ranging from rich coral reefs (Ref. 58652) to weedy and rubble covered areas (Ref. 1602). Benthopelagic (Ref. 58302). Maybe found singly, in pairs, and in aggregations that roam over large distances in search of food. Feed mainly by tearing pieces from polychaetes, sea anemones, coral polyps, and algae (Ref. 1602). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
