Occurs mainly in shoals in the middle water layers. Feeds on worms and small crustaceans (Ref. 7020). Breeding in captivity is possible but difficult and most specimens in the aquarium trade are caught in the tributaries of the Rio Negro and Orinoco. Eggs hatch in 24 to 30 hours and fry are free-swimming after 3 to 4 days in captivity (Ref. 7020). One of the most popular and beautiful aquarium fishes. Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).
在中央的水层中主要生活在浅滩。 吃蠕虫与小型甲壳动物。 (参考文献 7020) 繁殖在繁殖场是可能的，但是在水族贸易的困难而大多数的标本被在尼格罗河的支流与奥里诺科河捕获。 卵在 24 到 30 小时中孵化，而且在 3 到 4 天之后在繁殖场，鱼苗是游离于水中。 (参考文献 7020) 最受欢迎而美丽观赏鱼之一。 水族馆保持: 形成 5个或更多个体的群体; 水族馆最小体型 60 公分.(参考文献 51539)
