Species Information
Size	200mm or 7.9" SL. Find near, nearer or same sized spp.
Identification	Fishes of the genus Mystus Scopoli are small to medium-sized bagrid catfishes occurring in South Asia. Roberts (1994) recognized Mystus to have an elongate cranial fontanel reaching up to the base of the occipital process, long maxillary barbel, very long adipose fin, 11–30 gill rakers on the first gill arch and 37–46 total vertebrae, about equally divided between abdominal and caudal regions. He included only eight species under the genus. Mo (1991) characterized the genus to have a thin needle-like first infraorbital, twisted and thickened metapterygoid loosely attached to the quadrate by means of ligament or a small extent of cartilage. Jayaram & Sanyal (2003) and Ferraris (2007) respectively listed 44 and 33 species of Mystus as valid. Distinguished from congeners by their uniform color without any dark markings, approximately equal lengths of adipose and anal fin bases, and long maxillary barbels that reach at least to the base of the caudal fin. Nasal barbels longer than head.
Sexing	Males have an elongate genital papilla in front of the anal fin.
