Map fish lay eggs, they are oviparous fish, and they are fertilized and developed in vitro during reproduction. It usually takes 18 months for artificially farmed map fish to mature. Adult map fish will pair themselves. After successful pairing, the female fish will lay eggs and the male fish will be inseminated. After insemination, reproduction is completed.

1. Choose parent fish: Map fish mature for a relatively long time, and they need about 18 months to reach adulthood. Breeders need to choose some map fish with bright colors and healthy physique.

2, Prepare breeding environment: Map fish breeding is not limited by seasons, and breeders only need to ensure that their living environment is comfortable, and they can breed. Breeders need to keep the water temperature between 26-28 ℃ and the PH value between 6.5-7.5. Oxygen should be given regularly to ensure sufficient dissolved oxygen in water.

3. Mating: After the male and female fish are successfully paired, the female fish will lay eggs first, and then the male fish will be inseminated. After fish eggs become fertilized eggs, they complete reproduction.

4. Hatching: After fish eggs become fertilized eggs, breeders need to prepare a comfortable environment for them to hatch as soon as possible. Under normal circumstances, as long as the water temperature and quality are stable, they can hatch successfully in about 2-3 days. After waiting for a week or so, the small fish can move freely.
