Once the eggs are laid, the eggs can be removed by separating them from their parents and placed in another tank to ensure their survival, and then you must wait for them to hatch within 24 hours. After this time, the little fish are born, and they begin to swim in the next four days after their birth.

Another option to keep the future brood stable is to opt for a small tank that has a pH of 6.0 along with a hardness of 2 ° dGH and a temperature of 30 ° C to keep the water warm for the eggs. With this, you will get that the laying is on it instead of the leaves; in this case, the laying can be given in groups of only four due to space.

Tips for successful parenting
