Length at first maturity / Size / Weight / سن
Maturity: Lm 23.8, range 23 - 25 cm
Max length : 48.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 7248); بيشينه وزن گزارش شده: 2.9 kg (Ref. 5693); بيشينه سن گزارش شده: 7 سال ها (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).
