生物学特性     字汇 (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环发现于开放水域了; 通常成群, 在被在底部上寻找庇护所的底部上面的 4-5 公尺当有掠食者.(参考文献 27310)
