Biologia     Glossario (es. epibenthic)

Adults occur in lagoon, inshore, and offshore reefs (Ref. 9710). Usually seen solitary, often swimming well above substrate (Ref. 48636). Feed on algae, barnacle nauplii, copepods, fish eggs, and small gastropods. 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).
