The body is covered with two rows of overlapping bony plates and the species bears barbels around the mouth; it reaches about 21 cm. The fish lives in very diverse, often extreme habitats, from anoxic, densely vegetated still-water zones to slightly turbid streams, and can take up air through intestinal breathing.
