Environment
Provide at least 60 litres and a school of at least 8 individuals, as it is a very gregarious fish. It tolerates a wide temperature range (18 to 24 °C), which makes it compatible with lightly heated or unheated tanks, pH 6.5 to 7.5. A long aquarium with a little current and a lid suits this athletic, jumping swimmer.
Feeding
An undemanding omnivore, it accepts flakes, fine pellets and small live or frozen prey. Vary its diet to maintain its vitality. A few small meals a day are enough.
Tips & tankmates
Kept in too small a group, it can become nervous and harass its tankmates, especially their fins. Cover the aquarium well as it jumps easily. Avoid pairing it with slow species or those with long flowing fins, which its restlessness may stress.
