collected from a gentle slope (approx. 20%), with mixed patches of live coral and sand-rubble (about 10-20 m) and was encountered solitarily or in loose pairs. Individuals had fully erect the first dorsal fin, which is then gently undulated when the fish is approached at close range by a diver (Ref. 115084).
