There are three to six silvery patches along the back from the head to the base of the tail.Females of the species have a silvery-grey body with brown with worm-like markings on the head and front of the body. A black stripe runs from behind the gill cover to the base of the tail. The belly area has silvery spots. An orange mark extends from the anus along the lower body, and the eye has a black ring with a reddish-brown iris.
