Specimens were collected from a creek and in wide open environments, as river channels and bays of the upper Rio Paraguay basin in the periodically flooded areas known as the Pantanal. Known to be a zooplanktivore which also eats insects. Stomach contents predominantly has microcrustaceans (cladocerans, copepods and ostracods); insects (ephemeropterans, coleopterans and hemipterans); and/or small amounts of water mites, rotifers, fish scales, bryozoans, unidentified eggs, detritus, and sand (Ref. 57707).
標本被採集自一條小溪與在廣泛的開放環境, 當上面 Rio 巴拉圭流域的河道與海灣在那定期知道如 Pantanal 的洪泛區。 已知是也吃昆蟲的 zooplanktivore。 胃內含物主要有小型甲殼類動物 (水蚤，橈腳類的動物與介形蟲); 昆蟲 (ephemeropterans ，鞘翅目與半翅目昆蟲); 及[或] 少量的水小蝨，輪蟲，魚鱗，苔蘚蟲類, 未確認的卵，碎屑與沙子.(參考文獻 57707)
