Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 17.0 range ? - ? cm
Max length : 21.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 36377); 26.0 cm TL (female); 最大體重: 248.00 g (Ref. 125882)
A plankton feeder occurring mostly in swamps or flooded grounds of coastal zones, either in turbid or clear stagnant water (Ref. 35237). Possesses very long and very fine branchial archs which allow it to filter microorganism-rich waters of the flooded savannas and swamps which are its preferred habitats (Ref. 27188). Males are larger than females, attaining maturity between 17 and 22 cm. Reproduction takes place during the rainy season (Ref. 35237).
大部分出現在沼澤的一個浮游生物捕食者或在混濁或清澈的污濁水也氾濫了海岸區域的地面.(參考文獻 35237) 持有讓它過濾微生物的非常長而非常細的鰓弓-被水淹沒大草原與沼澤的豐饒水域那是它的優先棲息地.(參考文獻 27188) 雄性是大於雌性,達到在 17 與 22 公分之間的成熟。 繁殖在雨季的時候發生。 (參考文獻 35237)
