Adults are relatively common on exposed seaward reefs; occasionally on shallow lagoon reefs in areas of rich coral growth and clear water. Juveniles in protected coral areas (Ref. 48636). Benthopelagic (Ref. 58302). In pairs in Indonesia but schools in some Pacific locations (Ref. 48636). Often in pairs during breeding and feed mainly on scleractinian coral polyps. Easily approached (Ref. 9710). Oviparous (Ref. 205), monogamous (Ref. 52884). Minimum depth reported taken from Ref. 128797.
