Longueur à la première maturité / Taille / Poids / Âge
Maturité: Lm 23.8, range 23 - 25 cm
Max length : 48.0 cm TL mâle / non sexé; (Ref. 7248); poids max. publié: 2.9 kg (Ref. 5693); âge max. reporté: 7 années (Ref. 7248)
Prefers deep main river channels and floodplain lagoons (Ref. 7248) with sandy bottoms (Ref. 7248, 52307). Feeds primarily on snails, bivalves and insect larvae (Ref. 7248, 52307), rarely also on fish or plants (Ref. 52307). Ovophilic (Ref. 52307), female mouthbrooder (Ref. 7248, 52307), breeds in early summer (Ref. 7248). Up to 700 eggs may be laid per female and per brood; males construct shallow, rounded pits approximately 20-30 cm in diameter, preferably in regions containing vegetation (Ref. 52307).
