1. Choose parent fish: If you want guppy to reproduce, you should choose suitable parent fish. When choosing parent fish, it is best to choose some bright colors and strong bodies, so that the quality of offspring can be better.

2. Prepare breeding environment: Guppies need a stable environment when breeding, and breeders need to keep the water temperature at 26 ℃. If conditions permit, it is best to keep the PH value between 7.2 and 7.4, so that they will live more comfortably.

3. Mating: Guppies are oviparous. They are fertilized and developed in vivo. During reproduction, the male fish will put the reproductive foot into the drain hole of the female fish to complete fertilization. After fertilization, the small fish will not be born immediately, and they need to mature in the female fish before they can produce.

4. Production: The production time of guppy fish is relatively long, which usually takes about 3 hours. When they are in production, the breeder needs to observe carefully and try to avoid dystocia.

1. Stable environment: When guppy breeds, it needs to keep the surrounding environment stable. Although they have low requirements for the environment, they are sensitive to the fluctuation of reproduction, and breeders need to ensure the stability of their breeding environment. Especially the water temperature, the fluctuation should not exceed 2 ℃.

2. Quiet environment: Guppies are not only small in size, but also less courageous. Breeders need to keep their surroundings quiet, so as to avoid them being frightened and causing dystocia.

3. Isolated feeding: Guppies have no habit of protecting small fish, and breeders need to fish them out immediately after their parent fish are produced. Avoid newborn small fish being eaten as food by big fish.
