A thick-bodied, translucent-looking fish. This fish looks like both a trout and a perch. It has the adipose fin and naked head of the Salmonids, but the ctenoid scales, fin spines, and mouth shape similar to Percids. The mouth is horizontal and large with the upper jaw not reaching beyond the front of the eye. The tail fin is deeply forked with a fleshy adipose fin. The single dorsal fin has two weak spines and 10 to 11 rays. The anal fin has a single weak spine and 6 to 7 rays, and the pelvic fin has one spine with 8 to 9 rays. A lateral line is present with 47 to 58 scales. The back and sides are pale olive or straw-colored and the belly whitish. There are two longitudinal rows of dark spots along either side and a single mid-dorsal row. Adults are commonly 3- to 5-inches long.
