It inhabits freshwater systems including rivers, streams, and lakes. It occurs in Temperate waters. It is broadly omnivorous, taking invertebrates, plant matter, and detritus. On the IUCN Red List, it is classified as Least Concern.The species is important as a food fish, kept in the aquarium hobby, and considered a sustainable seafood option under current management.

🐟 Physical Description

Dorsal soft rays (total): 10; Anal soft rays: 8; Vertebrae: 40 - 42. Distinguished from all other species of Barbatula from northern Asia by having an upper lip with a marked and deep median indention (vs. slight and shallow) and a nearly scaleless body or scales only on the caudal-fin base (vs. body scaled posterior to the dorsal-fin origin or a fully scaled body). Can be further diagnosed from B. dgebuadzei in having closely-set nostrils (vs. widely separated) and 40-42 vertebrae (vs. 43-45). Similar to both Barbatula altayensis and B. sawadai in the shared presence of closely-set nostrils, a character distinguishing them from all other congeners from northern Asia with widely separated nostrils. Can be further diagnosed from B. altayensis in having 40-42 vertebrae (vs. 44-45), and from B. sawadai in having 7 branched dorsal-fin rays (vs. 8). Resembles B. compressirostrisi (or B. golubtsovii) and B. dgebuadzei in scalation in that the body is scaleless or scales only on the caudal-fin base. Further differs from B. compressirostrisi (or B. golubtsovii) in having 40-42 vertebrae (vs. 45-47) and closely-set nostril (vs. widely separated) .: elongated.
