Anale zachte stralen: 13 - 15; Wervels: 34 - 37. Differs from all other species of Mystus in having eyes lateral, rather than dorsolateral, so that they are about equally visible viewed either from above or from below head (in other species eyes usually cannot be seen at all from directly below). Mouth nearly terminal, less downturned than in any other species of striped Mystus. Serrae of pectoral spine smaller and less erect than in any other striped Mystus. Adipose fin short but very high, originating far behind dorsal fin, its length about twice and its height slightly less than eye diameter. Gill rakers increase in number throughout life faster than in any other Mystus. The anal fin has slightly more rays (13-15) than other striped Mystus of Thailand (usually 12 or less), and its posterior border is distinctly falcate. Cranial fontanel extends posteriorly to about midway between level of posterior border of eye and base of supraoccipital process. Maxillary barbel extends posteriorly to beyond anal fin or to end of middle caudal fin rays (Ref. 26663). Side of body with 3 faint dark and 2 whitish stripes (Ref. 43281).
Facultative air-breathing in the genus (Ref. 126274); Often found in mixed schools with M. multiradiatus which congregate around tree limbs and other solid objects, browsing the hard surfaces for zooplankton, aquatic insects, crustaceans and rotifers. Move into flooded forests during the rainy season and returns to rivers in November and December in the lower Mekong. Oviparous, distinct pairing possibly like other members of the same family (Ref. 205). Marketed fresh or smoked on a skewer (Ref. 12693).
