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).
在中央的水層中主要生活在淺灘。 吃蠕蟲與小型甲殼動物。 (參考文獻 7020) 繁殖在繁殖場是可能的，但是在水族貿易的困難而大多數的標本被在尼格羅河的支流與奧里諾科河捕獲。 卵在 24 到 30 小時中孵化，而且在 3 到 4 天之後在繁殖場，魚苗是游離於水中。 (參考文獻 7020) 最受歡迎而美麗觀賞魚之一。 水族館保持: 形成 5個或更多個體的群體; 水族館最小體型 60 公分.(參考文獻 51539)
