Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 13; Radios blandos dorsales (total) : 14 - 15; Espinas anales: 2; Radios blandos anales: 13 - 14.
Adults inhabit outer coral or rocky reefs. They usually form large aggregations in shallow waters e.g. in lagoons; feeding well above the bottom on zooplankton (Ref. 2334). Diurnal species (Ref. 54980; 113699). 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).
