পৃষ্ঠীয় কাঁটা (মোট ) : 1 - 3; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 35 - 38; পায়ূ কাঁটা : 3; পায়ূর নরম পাখনা্তুন্ড: 17 - 20; কশেরুকা : 46 - 49. Adults are brown to blackish along the sides, with variable mottled or blotched patterns bordered by yellow, and whitish ventrally (Ref. 33616).
Occur in cool, clear streams with rocky bottoms in mountain terrain (Ref. 33616); with fast to moderate flow (Ref. 44894). Often abundant at altitudes of 200-700 m (Ref. 33616). Benthic, nocturnally active species which usually occur solitary. Juveniles often found in large groups among leaf litter and wood debris. Movements are restricted to a relatively small stretch of river over the duration of the life span. Occur with G. marmoratus at lower elevations, but they have different habitat preferences. Feed on insect larvae, fishes, fish eggs, earthworms and crustaceans. Breed between October and December. Sexual maturity is attained after 2 years (Ref. 44894). Often caught by recreational fishers targeting trout, although not a desirable target due to its small size (Ref. 33616).
Male guard the eggs and developing larvae until yolk sac is almost completely resorbed (Ref. 35369).
