Breeding: They are hard to breed and the fry is sensitive. They prefer very soft acidic water. They lay their eggs among fine leaved plants. The breeding pair should be removed as soon as the spawning is completed as they sometimes eat their own egg and fry. (It is possible to breed this species in a permanent breeding aquarium tank.) Each spawning can result in over 500 eggs. The fry is very small and requires very small food.
