Các tia vây lưng cứng (tổng cộng) : 0; Các vây lưng mềm (tổng cộng) : 11 - 15; Động vật có xương sống: 34 - 38. Has 37-43 scales on the lateral line (including those on base of caudal-fin); 7-8+1/2 scale rows between lateral line and dorsal-fin origin (Ref. 27732). Differs from all other species of the genus in having more or less discrete marks on each scale on the upper, middle, and sometimes lower parts of the body. Such marks, visible in most freshly caught and recently preserved specimens, are sometimes intensely developed, giving the fish a markedly reticulated appearance. C. molitorella often has a very intense humeral mark which is vivid bluish-green in life. In other Cirrhinus the humeral marks are black or bluish black (Ref. 33488). Usually a conspicuous black bar shortly behind pectoral base (Ref. 43281). Gill rakers on the lower arm of first arch 65-85 (Ref. 12693).
Known from midwater to bottom depths of large and medium-sized rivers. Move into flooded forests during the rainy season and grazes on algae, phytoplankton and detritus (Ref. 12693). Occur in rapids and slow deep reaches (Ref. 37769). Reported to be omnivorous (Ref. 33813). Wild stocks are strongly migratory while the cultivated stocks probably have lost the migratory behavior (Ref. 33488). Prefer flowing water and not known to proliferate in impoundments. Large fish are marketed fresh, smaller ones are used to make prahoc (Ref. 12693). Attain at least 40 cm SL (Ref. 33488).
Assuming standard cyprinid mode of reproduction. Replace ASAP.
