Biologie     Glossaire (ex. epibenthic)

Adults are found in lagoons, harbors, and coastal reefs, shallow habitats, deep sand or mud slopes with outcrops of debris or coral rubble pieces, or on rocky substrates in sheltered bays. They usually occur in large aggregations, sometimes forming mixed aggregations with Neopomacentrus sp. Abundant around sponge-encrusted mooring buoys and their anchor lines and occur in smaller colonies around rocks and refuse (Ref. 1602). 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).
