Biologie     Glossaire (ex. epibenthic)

Adults are usually seen singly or in small groups on coastal reefs, amongst mixed algae-coral reef or rocky reefs (Ref. 48636). They are found on exposed seaward reefs; less abundant in lagoons and channels. Feed on zooplankton. 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. 113699).
