背棘 (總數) : 1 - 3; 背的軟條 (總數) : 35 - 38; 臀棘: 3; 臀鰭軟條: 17 - 20; 脊椎骨: 46 - 49. Adults are brown to blackish along the sides, with variable mottled or blotched patterns bordered by yellow, and whitish ventrally (Ref. 33616).
成魚是褐色到黑色的沿著側邊,有多變的與黃色接壤的有斑點的或大斑點圖案, 與微白色的腹地.(參考文獻 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).
