Etymology: Mystus: Greek, mystax = whiskered, used by Belon in 1553 to describe all fishes with whiskers (Ref. 45335).

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm SL male/unsexed; (Ref. 30857)
Vertebrae: 36 - 39. Has 3 faint dark and 2 whitish stripes on the sides; adipose fin longer than anal fin and almost contiguous with the dorsal fin; eyes not visible when head is viewed from below (Ref. 27732). Cranial fontanel extends posteriorly to about midway between posterior rim of eye and supraoccipital process (Ref. 12693).
Facultative air-breathing in the genus (Ref. 126274); Adults inhabit rivers, streams and reservoirs. Feed mainly on crustaceans and zooplankton along with small bits of algae and fish scales. May forage in schools like the other small striped species of Mystus. Move into floodplains during periods of high water and is often found in places with submerged woody vegetation. Oviparous, distinct pairing possibly like other members of the same family (Ref. 205). Usually marketed fresh and may also be sold smoked (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00422 - 0.01973), b=2.92 (2.75 - 3.09), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.45 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
