Olive to greenish-blue over most of the upper body, fading to a silvery-white along the belly. They are most easily separated from the other trout species by the strikingly prominent pink-red horizontal stripe that extends down each side of the fish. The sides, back, dorsal and caudal fins have small black spots continuing to the distal end of the caudal fin. Like most trout, there are sharp teeth on the vomer in the roof of the mouth. Scale counts along the lateral line range from 135 to 155.
