生物学特性     字汇 (例如 epibenthic)

Adults inhabit coral rich areas of outer reef passes and slopes. They occur singly or in small groups near the bottom (Ref. 7247). Diurnal species (Ref. 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).

栖息于外围礁石海峡与斜坡的珊瑚丰富的区域。 各别地生存或形成小群鱼群在底部的附近。
