Maturity: Lm 23.8, range 23 - 25 cm
Max length : 48.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 7248); 最大体重: 2.9 kg (Ref. 5693); 最大年龄: 7 年 (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).
偏爱深的主要河道与洪泛区泻湖且底部为沙地的地方。 主要吃蜗牛，二枚贝与昆虫幼生。 一条母鱼口孵者, 在初夏繁殖。

营养阶层 (Ref.
69278): 3.5 ±0.52 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
