Under normal feeding conditions, guppies need 3-6 months to develop into adults. Their growth rate is affected by the feeding environment. If they live in a comfortable environment, they are likely to develop into adults in about 3 months. If they live in a poor environment, the guppy's physique will also deteriorate, and the adult time will be longer.

If breeders want them to grow faster, they'd better feed them more nutritious food and ensure that their living environment is comfortable. In this way, they can grow faster and have better physique.

1. Mating of parent fish: guppies are oviparous. When they reproduce, males and females will pair first. After successful pairing, male fish and female fish will mate. After mating, they don't reproduce immediately, and they need to wait about 28-32 days before giving birth.

2. Pregnancy: After guppy is pregnant, breeders need to prepare enough food for them, and keep the water temperature and water quality stable, so that fish eggs can develop better in their bodies.

3. Production: When guppy is produced, the breeder needs to prepare a separate breeding tank for them, and adjust the water temperature and water quality in the breeding tank to be consistent with the original tank, so that they can produce better. The small fish produced by guppies do not swim immediately, so the breeder does not need to feed them directly. After the small fish can swim horizontally, the breeder will feed some shrimp eggs and cooked egg yolks in good years.
