Max length : 12.0 cm SL con đực/không giới tính; (Ref. 57127)
Các tia vây lưng cứng (tổng cộng) : 0; Các vây lưng mềm (tổng cộng) : 0; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 60 - 78; Động vật có xương sống: 44 - 50. Diagnosis: dorsal fin absent; adipose fin always present; inner side of pectoral-fin spine variably denticulate, with small to rather well developed serrations; 60-78 soft rays in anal fin (Ref. 43912, 57127, 81643). Vomerine teeth present (Ref. 43912, 81643). In general no small dark blotch at the base of the caudal fin (Ref. 81643).
Gregarious schooling species confined to larger lakes and rivers (Ref. 43912). Benthic species, occurs in deep water (Ref. 13851). Feeds mainly on small planktonic and benthic insects and crustaceans (Ref. 13851, 43912). Oviparous, eggs are unguarded (Ref. 205). Rarely exceeds 15 cm TL (Ref. 43912). Usually smoked or sun-dried, after which they are very tasty and may fetch high prices; sometimes ground into fish flour or fish meal and stored for long periods in sealed containers as an insurance against famine (Ref. 43912).
Distinct pairing (Ref. 205).
