Adults are found in 1-6 m (Ref. 7247) and in coastal to outer reef crests to depths of about 20 m (Ref. 48636). They occur solitarily or in groups in reef margins and upper seaward slopes subject to mild surge (Ref. 9710). Feed mainly on algae. Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
