Adults occur in clear lagoon and seaward reefs from the lower surge zone to a depth of 30 m (Ref. 1602). Usually in areas with mixed rubble, coral, or rock and sand (Ref. 9710). Usually solitary among large corals. Small juveniles swim with their head down, keeping dorsal and anal fins erected, and may seem like the face of a larger fish when viewed from side on by a predator (Ref. 48636). Oviparous, distinct pairing during breeding (Ref. 205). Occasionally seen in fish markets and aquarium trade.
