生物學特性     字彙 (例如 epibenthic)

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).

出現於冷的, 清澈溪流,底部為岩石的地方在山地帶中。 時常豐富的在 200-700 公尺的高度.(參考文獻 33616) 時常被鎖定鱒魚的一般釣客捕獲了, 雖然不是一個令人滿意的目標由於它的體型小。 (參考文獻 33616)
