Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 23.8, range 23 - 25 cm
Max length : 48.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 7248); 最大體重: 2.9 kg (Ref. 5693); 最大年齡: 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).
偏愛深的主要河道與洪泛區潟湖且底部為沙地的地方。 主要吃蝸牛，二枚貝與昆蟲幼生。 一條母魚口孵者, 在初夏繁殖。
