The front half of the body is flattened and tapers towards the front. The snout is pronounced and rounded when viewed from above. The dorsal and anal fins are prolonged and flattened and are not connected to the caudal fin. The caudal fin and pectoral fins are rounded in shape. The pelvic fins are modified into a specialised sucking disc which give the fish its name. Flattened papillae are present in 3-5 rows across the disc region. Males are generally reddish above with bright red spots on the head. Females are yellowish-green.
