背棘 (总数) : 8 - 13; 背的软条 (总数) : 10 - 14; 臀棘: 1 - 3; 臀鳍软条: 8 - 12; 脊椎骨: 43 - 45. The presence of 57-65 + 3-6 scales along lateral line distinguishes uniquely this species from its congeners. Can be further separated from other species by the combination of the following characters: first dorsal fin with 8-9 spines; second dorsal fin with 1-2 simple and 9-12½ branched rays; scaleless cheeks (Ref. 59043). Caudal fin with 17 soft rays (Ref. 40476).
尾鳍有 17个软鳍条。 (参考文献 40476)
A short-lived species reported to live in fast-flowing rivers with a gravel substrate (Ref. 30578). Occurs in main course of rivers and large streams and in riffles. Found on stone bottom (Ref. 59043). Lurks on the bottom during the day and comes out for crepuscular feeding (Ref. 11941). Feeds on aquatic invertebrates. Larvae feed on plankton under surface, then at about 2.5 cm SL, they move to benthic habitats. Attains first sexual maturity at 2-4 years of age. Spawns in deeper parts of riffles. Deposits on gravel strongly adhesive eggs, 2.2 mm in diameter, which hatch in about 14 days at 13° C (Ref. 59043). Threatened due to habitat destruction and pollution (Ref. 26100).
一种生命期短的种是发现于快速流动的河具有一个砾石底部.(参考文献 30578) 然后变成底栖的它何时达到 2-2.5 公分的大小，最初大洋性。 产卵在三月到四月,在石头或植物之上。 在底部上的潜伏在白天期间而且为晨昏的进食出来.(参考文献 91141) 吃小型无脊椎动物，昆虫幼生与小型甲壳动物。 (参考文献 30578) 受到威胁的由于栖息地破坏与污染.(参考文献 26100) 非常稀有的鱼.(参考文献 30578)
