Adults occur in fresh water, often well inland. Found over sand streams, usually in current near cover (Ref. 86798). Inhabits larger free flowing clear water streams (Ref. 11225). They lie mostly on the bottom in slower moving part of streams, sometimes on logs or large stones and on leaf debris or gravel (Ref. 11225). A carnivorous and benthic fish that relies on its sluggish behavior and cryptic coloration (Ref. 36880). Feeds on all greater invertebrates and regularly also fish (Ref. 92840).
成鱼出现在淡水, 时常相当深入内陆。 栖息于比较大的自由流动的清澈水域溪流。 (参考文献 11225) 大部份在溪流的比较慢的移动部份中的底部上躺卧, 有时在圆木或大的石头与树叶碎片或砾石上.(参考文献 11225) 仰赖它的缓动性行为与善于隐藏的颜色取得甲壳类动物和鱼类的一个肉食性与底栖的鱼.(参考文献 36880)
