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).
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).
