Body shape (shape guide): fusiform / normal.
Adults inhabit rocky pools near riffles in clear to fairly turbid creeks and small to medium rivers (Ref. 86798). They feed on terrestrial insects, filamentous and unicellular algae, and a variety of aquatic invertebrate often dominated by mayfly nymphs (Ref. 10294). Oviparous (Ref. 205), nest spawners (Ref. 52559). Migratory behaviour is undetermined (Ref. 126106).
在急流的附近栖息于岩石的水池在清澈的对非常浑浊的小溪及小型到中型河川。
