Inhabits sandy and rocky riffles, runs and pools of clear creeks and small rivers and also springs. Greatly resembles a small channel catfish, however, body lacks spots and the caudal fin is not deeply forked, the base of the anal fin is longer than the head length (see Ref. 3221).
栖息于沙与岩石的急流，清澈小溪与小河与及水泉的小支流与水潭。 然而,与一个小的峡道鲶鱼非常相似, 身体缺乏斑点与尾鳍深深地不被分岔, 臀鳍的基底是长度超过头长.(见参考文献 3221)
