Espinas dorsales (total): 15 - 18; Radios blandos dorsales (total): 11-13; Espinas anales 3; Radios blandos anales: 9 - 11; Vértebra: 30 - 32. Diagnosis: jaws of mature male not greatly enlarged (length of lower jaw 29-37 % of head length); genital papilla of breeding male not tassellated (Ref. 2). Most distinguishing characteristic is the presence of regular vertical stripes throughout depth of caudal fin (Ref. 4967, 53405).

Occur in a wide variety of freshwater habitats like rivers, lakes, sewage canals and irrigation channels (Ref. 28714). Mainly diurnal. Feed mainly on phytoplankton or benthic algae. Oviparous (Ref. 205). Mouthbrooding by females (Ref. 2). Extended temperature range 8-42 °C, natural temperature range 13.5 - 33 °C (Ref. 3). Maximum depth from Ref. 34290. Marketed fresh and frozen (Ref. 9987).
