Occurs over muddy, sandy and rocky substrates, preferably in water deeper than 6 m. A real benthivore: specimens smaller than 10 cm FL mainly eat insect larvae, but also zooplankton and ostracods. With increased size, adult insects, mollusks and detritus also become important (Ref. 35835).
生活在泥泞的沙与岩石底部之上, 可能地在深度超过 6 公尺的水域中。 一个真正的底部觅食者: 比 10 公分 FL 小的标本主要地吃昆虫幼生, 也浮游动物与介形虫。 随着体型增大, 昆虫成虫, 软件动物与碎屑也变成很重要.(参考文献 35835)
