Spawning sometimes can be triggered by a partial water change. A successful mating will be confirmed by the arrival of eggs, usually tiny transparent spheres. As most fish cannot pass up a free meal it is now time to remove the parents. The tank should also be darkened if possible. It is very important to remove any nonviable eggs as mold could destroy the entire clutch.
Viable eggs remain transparent throughout their development.
Incubation is usually very short between twenty and thirty hours. Newly hatched fry will still have a yolk-sac and once that is absorbed feeding should start with newly hatched brine shrimp. Feed in small amounts and often. Dead food should not be allowed to remain on the bottom. Keep up the water quality and good food and growth will be very rapid.
