; 淡水 底中水層性; 深度上下限 6 - ? m (Ref. 35835). 熱帶; 13°N - 11°N

Maturity: Lm ? range ? - ? cm
Max length : 63.5 cm FL 雄魚/尚未辨別雌雄; (Ref. 35835)
背棘 (總數) : 0; 背的軟條 (總數) : 11 - 13; 臀棘: 0; 臀鰭軟條: 8. Body depth 1 to 1.1 times in head length; ventral fin length less than 1.7 times in head length; nuchal hump starts gradually at occiput; silvery white.
體高 1 到 1.1 倍頭長; 腹鰭長度少於 1.7 倍頭長; 頸背的隆起逐漸地在後腦部開始; 銀白色。
Occurs especially over muddy and sandy substrates all over the lake, preferably in water deeper than 6 m. A benthivore that at a larger size turns into a piscivore. Specimens smaller than 15 cm FL mainly eat insect larvae. Mollusks and plant material become more important with increased size. When fish reach sizes of 25 cm FL or more, fish are their main food.
生存尤其在泥濘多沙的底部之上在湖中各處, 可能地在深度超過 6 公尺的水域中。 一個在一個較大變成一個食魚動物的底部覓食者。 比 15 公分 FL 小的標本主要地吃昆蟲幼生。 軟體動物與植物變得更重要的隨著體型增大。 當魚達到 25個公分 FL 或更多的大小的時候，魚是他們的主要食物。
