Adult individuals sport a splendid golden orange to yellow hue on their flanks, gradually fading into silvery white on their bellies. Their fins gleam with a resplendent yellow, and they sport two pairs of short barbels at the corners of their mouths. The Golden Mahseer reigns supreme in large rocky pools and rapids, feasting on a delectable menu of worms, insects, mollusks, and small fish.
