1, spawning: Colorful fairy fish need an oviposit tube when laying eggs, because they need to lay their eggs in the tube. Breeders should also ensure that their production environment is comfortable, the water temperature should be kept above 28 ℃, and the water quality should be clean and refreshing. If conditions permit, it is best to install an oxygen pump to ensure sufficient oxygen in the water. Under the condition of ensuring a comfortable production environment, the female fish will start to lay eggs. They are fertilized in vitro. After the female fish lays their eggs in the production tube, the male fish will come forward to fertilize.

2. Hatching: The male fish begins to hatch after successful insemination. When hatching, the colorful fairy fish will always guard the eggs. Under the condition of keeping the environment stable, fish eggs can hatch successfully in about 2-3 days. Small fish that hatch successfully do not need to be fed immediately, because nutrient solution will be produced in parent fish, and small fish will suck nutrient solution from parent fish. After the small fish take off, the breeder can try to feed the food again.

As long as the breeder can ensure the stable environment for their production and hatching, the success rate of their reproduction is still relatively high. Because the parent fish will guard the fish eggs and the small fish will attach to the parent fish after hatching, the survival rate of the small fish is relatively high as long as the parent fish lives comfortably.
