生物学特性     字汇 (例如 epibenthic)

Adults are found at the upper edges of steep outer reef slopes. They occur singly or in small groups. Feed on zooplankton and algae (Ref. 7247). 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).

发现在陡峭外礁斜坡的上缘了。 各别地或形成小群鱼群生存。 吃浮游动物与藻类。
