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.

Easily characterized by its dull-colored body and very short adipose fin.
There are several species currently identified as M. gulio: the true M. gulio is an Indian species that grows much larger than those from Southeast Asia, and is a more greenish (vs. grayish) color.
Sexing Males have an elongate genital papilla in front of the anal fin.
General Remarks Primarily a brackish water fish that enters and lives in fresh water. In freshwater, it occurs mainly in larger water bodies (rivers and streams) with mud or clay substrates, and rarely found in smaller streams.
