Biology     Glossary (e.g. epibenthic)

Adults inhabit coral and rocky reefs, juveniles often commensal with large sea anemones, sea urchins, or small coral heads (Ref. 4391, 48636). They occur in small to large aggregations. Stomach contents include algae, copepods, and other 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).

IUCN Red List Status (Ref. 115185)
