背的軟條 (總數) : 9 - 10; 臀鰭軟條: 19.
Inhabits small black water streams in areas forested by the palm Maurita flexuosa. Usually occurs in the gallery forest areas in pools of small streams of 2-4m wide. The water depth where this species occurs is usually 20-60cm and the current is slow. The bottom is usually sandy but may be pebbly and with much forest debris. Commonly found near the shoreline where they can seek protection from predators among vegetation. Commonly swims near the surface of the water in schools of about 20 to 80 individuals.
棲息於小的黑色水溪流在長著手掌 Maurita flexuosa 植物的區域. 通常出現於在 2-4 公尺寬的小溪流的水池中長廊森林區域中。 這種出現的水深度通常是 20-60 公分與水流慢。 底部通常是沙的但是可能是多礫石的而且有很多的森林殘礫。 普遍地在海岸線附近發現在那裡它們能尋找保護以躲避在植物之中的掠食者。 通常巡游水的表面形成大約 20 到 80個個體的魚群。
