Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. 45335); lepidurus: From the Greek "lepis" = scale and "oura" = tail, referring to the densely scaled caudal fin (Ref. 55074).

পৃষ্ঠীয় কাঁটা (মোট ) : 15 - 17; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 9 - 12; পায়ূ কাঁটা : 3; পায়ূর নরম পাখনা্তুন্ড: 8 - 9; কশেরুকা : 28. Diagnosis: mature male with tuberculate genital papilla, some of the tubercles prolonged into filaments (Ref. 2). Caudal fin of adults densely scaled, usually with a reticulate melanin pattern (Ref. 2, 55074). 28 vertebrae; total dorsal rays 24-27; 19-24 lower gill-rakers; in adults snout long, preorbital bone deep and blade of lower pharyngeal 2-2.3 times the median length of the toothed area; outer teeth of jaws bicuspid unless by wearing down of minor cusp (Ref. 2).
Microphagous, using plankton (Ref. 2, 55074). Maternal, ovophilic mouthbrooder (Ref. 52307).
