生物学特性     字汇 (例如 epibenthic)

Adults inhabit coral-rich areas of clear lagoon and seaward reefs. They occur singly or in small groups and remains close to thickly branching coral shelter (Ref. 9710). 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. 54980; 113699).

栖息于清澈的泻湖与临海礁石的珊瑚礁繁盛区域。 各别地生存或者形成小群鱼群而且厚地逗留在接近树枝状珊瑚庇护所.(参考文献 9710)
