Short description
Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 7; Mjukstrålar i analfenan: 15 - 17; Ryggkotor: 40 - 43.
Inhabits clear, swift, moderate to large high gradient streams. Occurs in swift shallow riffles with gravel, cobble or large stone substrate, but can occasionally be found in shallower pools (Ref. 57745).
