The attachment of the dorsal fin lies in front of the base of the pelvic fin. The dorsal fin is supported by 3 to 6 unbranched and 7 to 12 branched soft rays. In the anal fin there are 3 to 4 unbranched and 4 to 6 branched soft rays. The scales are tiny and get larger towards the tail. There are also unscaled species.

There are three pairs of barbels on the upper jaw , two near the tip of the mouth and another near the corner of the mouth. The pharynx are small and arranged in a row.
