Mature map fish can breed once a week after entering the breeding season. Although they reproduce frequently, it is not recommended that they reproduce so frequently. Because frequent production will not only affect the quantity and quality of reproduction, but also cause great harm to the mother. Therefore, it is recommended to breed them once every 1-2 months when raising them artificially.

Map fish can reproduce 2-4 times a year, but the specific number and frequency of reproduction are affected by the surrounding environment. If the living environment is comfortable, they will reproduce more times, usually 3-4 times. If the living environment is poor, they will reproduce less frequently, and they can only reproduce 1-2 times a year.

1. Choose parent fish: If you want map fish to reproduce, you must prepare mature parent fish. In addition to mature, parent fish should have better body shape and physique, so that the quality of the next generation can be better.

2, Ready to breed: After selecting parent fish, they should be put into a special breeding tank. The temperature in the breeding tank should be kept between 26-28 ℃, the PH value should be kept between 6.5-7.5, and the dissolved oxygen in the water should not be less than 6 mg per liter. After the breeding environment is prepared, the parent fish begin to pair and breed by themselves. When map fish breed, the female fish will lay eggs first, and then the male fish will come forward to inseminate, and the breeding process will last about 3 hours.

3. Hatching: Fish eggs hatch after fertilization. In a comfortable environment, fish eggs can hatch successfully in 2-3 days.
