生物學特性     字彙 (例如 epibenthic)

Adults are found in open areas with great water circulation over rocky bottom; usually in groups, 4-5 m above the substrate, seeking shelter on the bottom when there are predators (Ref. 27310). 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).

用在岩石的底部上的大水循環發現於開放水域了; 通常成群, 在被在底部上尋找庇護所的底部上面的 4-5 公尺當有掠食者.(參考文獻 27310)
