Occurs in very shallow rocky biotopes, usually at exposed sites. Mostly found in the upper 2 m. Feeds mainly from the water column; on plankton when this is available and on insect larvae and other invertebrates that appear in the open water. Has also been observed feeding from the biocover on the rocks (Ref. 5595).
出现于很浅的岩石生存环境, 通常在裸露的位置。 大部份发现于上面的 2 公尺了。 主要地为食从水中; 在浮游生物上当这是有用的时候与在昆虫幼生与其他的在开放水域中出现的无脊椎动物上。 已经也在岩石上被观察摄取食物的从附着生物。 (参考文献 5595)
