Feeding: Always hungry, eats all standard Aquarium foods
Breeding: Hard to spawn and not very productive when it does. Spawning requires water with a low pH and very soft with a temperature around 80° F. Only produces about 50 eggs. Hangs it's eggs from plant leaves.
Comments: A very desirable small and undemanding fish. Harlequins are great schoolers, always active and are made to order for a planted tank. Harlequins can live up to 5 years.
