Descrição breve
Morfologia | Morfometria
Espinhos dorsais (total): 15 - 17; Raios dorsais moles (total): 10-11; Espinhos anais 3; Raios anais moles: 8 - 9; Vértebras: 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).
Life cycle and mating behavior
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
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).
