Adults swim mainly in the upper and middle water layers. Feed on worms, small insects and crustaceans (Ref. 5723). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51150). Mature males always with gill glands and hooks in the anal fin ray (Ref. 58431).
成魚游泳主要在上游與中游的水層。 捕食蠕蟲，小的昆蟲與甲殼動物。 (參考文獻 5723) 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 51150) 在臀鰭鰭條中有鰓腺與鉤總是成熟的雄魚。 (參考文獻 58431)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
In the tank, spawning occurs usually in early morning, after a period of very active driving by the male. Female lays numerous glass-clear eggs, sometimes 700 to 800, which sink to the bottom of the tank. Eggs hatch in about 20 to 25 hours (Ref. 7020).
Number of hooks present in the anal fin rays and frequency of occurrence of gill glands suggest stage of maturation in males (Ref. 58431).南美洲: 巴拉納河流域。
