Body length up to 13 cm, weight up to 45-50 g. Life expectancy, apparently, about 5 years. The body is elongated, slender, relatively high, moderately compressed laterally, covered with medium-sized scales, which on the belly reach only the posterior ends of the pectoral fin bases (chest and throat completely naked). The caudal stem is laterally compressed, relatively short, its height is greater than the thickness at the level of the last ray of the anal fin. The head is large, with a relatively long snout. The forehead is not wide, the eyes are small. The antennae are long, usually they go beyond the front edge of the eye to its middle, sometimes they do not reach or reach the front edge of the eye, sometimes to its posterior edge. The anus is closer to the anal fin than to the abdominal. The general background color is ash-silver with a blue or green tint. On the back there are up to 7-11 weakly expressed small spots, on the sides along the lateral line of spots there are usually 8-12, sometimes more. The spots are clear, rounded, dark. Sometimes on the back they partially merge into a strip. The dorsal, caudal, and pectoral fins are gray with several (up to 5-6) transverse rows of dark dots; all other fins are colorless.

The biology of this species has not been specifically studied, but in many ways similar to that of other species of minnows living in foothill and mountain zones. Freshwater river bottom flock of residential fish of clean and well aerated waters of rivers and reservoirs. It is kept in secluded places of the coastal zone of rapid streams and rivers with a fast current, finding shelter among large stones, flooded trees, under washed banks, etc.
It reaches puberty in 2-3 years of life. Reproduction from late April to late June-early July. Fertility is 1-5.4 thousand eggs. Portion spawning occurs in shallow water (at depths of 20–50 cm) at a water temperature of 12–13 ° C or more. Caviar is sticky, deposited on stones, pebbles, dense sand, sometimes on vegetation. Juveniles feed on small organisms of plankton and benthos , adult fish feed on benthos animals (worms, insect larvae, lower crustaceans, etc.), as well as eggs and juveniles of other fish, partially detritus and vegetation.
