Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 12; Radios blandos dorsales (total) : 9 - 11; Espinas anales: 2; Radios blandos anales: 9 - 11.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Adults are found in large aggregations above thickets of branching Acropora corals in sheltered areas such as subtidal reef flats and lagoons. Juveniles closely tied to individual coral heads (Ref. 9710). Phytoplankton feeders. Breeding is done on sand and rubble. Males prepare nest for spawning which is shared with several females. Large number of eggs spawned hatching in 2-3 days. Males guard the nest ventilating fertilized egg with their caudal fins and feeding on those which do not hatch. Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Diurnal species (Ref. 54980; 113699).
