পৃষ্ঠীয় কাঁটা (মোট ) : 15 - 17; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 10 - 11; পায়ূ কাঁটা : 3; পায়ূর নরম পাখনা্তুন্ড: 8 - 9; কশেরুকা : 29. Diagnosis: mouth terminal (Ref. 26185, 53940). Distinctive fleshy lips (Ref. 26185, 52307), from which protrude rows of outwardly directed jaw teeth (Ref. 26185, 53949). Inner jaw teeth usually with 3 subequal cusps, outer row notched in juveniles but with simple replacements in adults (Ref. 26185, 53940). 7-8 lower outer teeth, 12-23 upper outer teeth; blade and dentigerous area of lower pharyngeal bone subequal, with slender teeth, firm and unicuspid posteriorly; colour variable, often silver-yellow (pale or intense) with dusky mottling concentrated on head and, to a lesser extent, midline (Ref. 26185). No Tilapia-spot on dorsal fin (Ref. 26185, 52307, 53940, 53949). Metallic blue highlights on operculum, dorsal and caudal fins (Ref. 26185).
Usually found in smaller groups (Ref. 52307) in shallow waters of lake shore (<4 m deep)(Ref. 26185). Feeds mainly on benthic invertebrates (mayfly, caddis and chironomid midge larvae) (Ref. 26185) and the endemic sponge Corvospongilla thysi (Ref. 53950, 58527, 81260), but diatoms and terrestrial macrophytes are also sometimes eaten in quantity (Ref. 26185). Maternal (Ref. 52307) mouthbrooder (Ref. 13614, 52307, 58527).

Eggs green (Ref. 26185, 53940, 58527) and ovoid, large (4x3mm) and few in number (Ref. 26185, 53940). Female is mouthbrooding (Ref. 13614), but possibly variable biparental mouthbrooder (variably one of the parents or both incubate eggs)(Ref. 58527).
