Etymology: Mystus: Greek, mystax = whiskered, used by Belon in 1553 to describe all fishes with whiskers (Ref. 45335). More on author: Bloch.
Environment: milieu / climate zone / depth range / distribution range
; acqua dolce; salmastro demersale; pH range: 6.0 - 7.5; dH range: 4 - 25. Tropical; 22°C - 28°C (Ref. 1672); 38°N - 0°N
Asia: Indian subcontinent, including Pakistan, India, Sri Lanka, Nepal, Bangladesh and probably Myanmar. Reported from Malaysia (Ref. 4835), Laos (Ref. 4792), Bhutan (Ref. 9418), Viet Nam (Ref. 36625) and Cambodia (Ref. 36654). May have been confused with other Mystus.
Length at first maturity / Size / Peso / Age
Maturity: Lm 9.0, range 9 - ? cm
Max length : 21.0 cm SL maschio/sesso non determinato; (Ref. 4833)
Spine dorsali (totale): 1; Raggi dorsali molli (totale): 6-7; Spine anali 0; Raggi anali molli: 12 - 13; Vertebre: 31 - 37. Body elongate and slightly compressed. Maxillary barbels extending beyond the pelvic fins, often to the end of the anal fin. Dorsal spine weak, finely serrated on its inner edge. Adipose fin small, inserted much behind rayed dorsal fin but anterior to the anal fin. Color in life varies with age; generally delicate gray-silvery to shining golden, with several (about 5) pale blue or dark brown to deep black longitudinal on side. A narrow dusky spot often present on the shoulder. The fins glass, with dark tips (Ref. 4792).
Adults inhabit standing and flowing waters. Usually found among marginal vegetation in lakes and swamps with a mud substrate. Feed on plants, shrimps, insects, mollusks and fish (Ref. 6028). Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).
