Breeding Notes

Eggs are laid in top mops or floating vegetation. Mostly found near the waters surface. Hatching takes 12 - 18 days in water at 20°C. Fry on hatching are able to take newly hatched brine shrimp. Fry stay near the waters surface & a shallow fry rearing tank is preferred.
Some breeders recommend using only soft water to incubate the eggs.

Sterba in Freshwater Fishes reported that egg incubation takes 3 weeks.

Diameter of Egg Given as 'relatively large' by Sterba in Freshwater Fishes'. Some breeders put the size at 2 mm.
Remarks

Dither fish such as guppies have been used by some breeders to help the fish take dried foods. Mosquito larvae appear to be the favoured food.
