生物学特性     字汇 (例如 epibenthic)

Adults inhabit lagoon and seaward reefs. Abundant, in large aggregations over reef tops and upper edges of slopes (Ref. 9710). Usually seen solitary in reefs, staying close to the substrate in depths of about 10 m (Ref. 48636). Diurnal species (Ref. 52881. 120737). 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).

栖息于泻湖与临海礁石。 丰富的, 较大时在斜坡的礁顶与上缘上的群集.(参考文献 9710) 通常在礁单独的被看到了, 停留在深度大约 10 公尺中接近底部。 (参考文献 48636)
