Adults inhabit clear lagoon and seaward reefs among branching corals. They occur in small aggregations. Feed mainly on algae and planktonic crustaceans (Ref. 7247). 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). Diurnal species (Ref. 54980; 113699).
