This species is distinguished by the following characters: lateral line incomplete; pored scales rarely more than 24 (mode 8); barbels are well-developed, length reaching but not surpassing 1.8 mm (Ref. 124213).
Cross section: compressed.
It is tolerant of turbid and eutrophic habitats from foothill streams to mainstem sections of major rivers and manmade impoundments and it does not penetrate into upper reaches of mountain tributary streams with oligotrophic water (Ref. 124213). It probably feeds on insects, zooplankton, seeds, green algae and diatoms. Oviparous (Ref. 205). Breeds during summer when rivers are swollen after rain and lays adhesive eggs amongst vegetation. It is probable that it is preyed upon by larger fishes and birds like other species (see Ref. 7248 & 5214).
