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).
似乎居住于河的更上游部份在哪里它占领水团的上半部。 活跃的在薄暮, 主要捕食昆虫与小型甲壳动物。 第一性成熟发生于 16 公分的长度。 繁殖开始于那雨季的初始。 体内受精, 母鱼能保持精液在生殖道的上皮中。 孕卵数大约是 15,000个卵。 (参考文献 35381)
