Appears to inhabit the more upstream parts of rivers where it occupies the upper part of the water column. Active at dusk, feeding mainly on insects and small crustaceans. First sexual maturity occurs at a length of 16 cm. Reproduction begins at the start of the rainy season. Fertilization is internal, the female being capable of keeping the sperm in the epithelium of its genital tract. Fecundity is approximately 15,000 eggs (Ref. 35381).
似乎居住於河的更上游部份在那裡它佔領水團的上半部。 活躍的在薄暮, 主要捕食昆蟲與小型甲殼動物。 第一性成熟發生於 16 公分的長度。 繁殖開始於那雨季的初始。 體內受精, 母魚能保持精液在生殖道的上皮中。 孕卵數大約是 15,000個卵。 (參考文獻 35381)
