Notes on guppy breeding:

1. The environment is stable. When guppies breed, they need to keep the surrounding environment stable, especially the water temperature, which should not fluctuate by more than 2°C.

2. The environment is quiet. Guppies are not only small in size, but also relatively timid. Breeders need to keep the surrounding environment quiet to prevent them from being frightened and causing dystocia.

3. Mixed breeding of males and females. Feeding male and female fish together during the mating period can reduce interference from other fish and increase the mating rate of male and female fish.

4. Supplement nutrition. Pregnant female fish should be fed nutritious food, which can enhance the female fish's physique and facilitate the development of fertilized eggs.

5. Isolated breeding. Guppies do not have the habit of protecting small fish. After the parent fish are born, the breeders need to fish them out immediately. Prevent the newborn fish from being eaten by the big fish as food.

6. Midwifery at any time. During breeding, specialized personnel must be responsible for guarding the fish, and problems must be dealt with in a timely manner to prevent the female fish from not giving birth in a timely manner when she has dystocia.
