Inhabits slow flowing waters that are only rarely deeper than 30 cm and connected to standing marshy area; over muddy bottoms (Ref. 26130, 36880). Lives between 35 and 600 m elevation at temperatures of 23-30°C. Swims in small groups near the surface of turbid waters, on the shoreline or among the undergrowth. Feeds on unicellular algae, diatoms, ooze and sometimes insect larvae (Ref. 36880).
棲息於慢的流動水域那是只有很少深度超過 30 公分而且連接到不動的多沼地的區域; 在泥沙底上面。 (參考文獻 26130,36880) 在 23-30個 ° C. 的溫度生活在 35 與 600 公尺海拔之間 混濁水域的群游於小群魚群中接近水表面, 在海岸線上或在下層叢林之中。 吃單細胞的藻類，矽藻，軟泥與有時昆蟲幼生.(參考文獻 36880)
