How long does guppy produce small fish after spawning, and how can it breed small fish

Guppies produce small fish, because they are oviparous fish, and the way of reproduction is fertilization and development in vivo. When the guppy mother is pregnant and fertilized, the eggs will develop in the mother's body, and they will not be born until they are mature, so it takes 20-30 days for guppy to give birth after pregnancy. There are many differences between oviparous life and viviparous life. They have no great connection with the mother, and they all rely on the nutrition in the yolk to grow and develop.

1. How long will guppies give birth to small fish after laying eggs

guppies do not lay eggs, but give birth to small fish. Because guppies are oviparous small fish, they are fertilized and developed in vivo. When guppy females become pregnant, males mate with them and fertilize their eggs. After fertilization, the eggs will be born in the body of the female fish for about one month, so the guppy will directly produce small fish when it is produced. The biggest difference between oviparous and viviparous is the connection with mother. Oviparous fish develop by vitellogenin in yolk, while viviparous animals rely on umbilical cord for nutrition.

2. How can guppies breed small fish

1. Keep the environment comfortable: If breeders want guppies to breed, they must prepare a comfortable living environment. If conditions permit, it is best to install a heating rod to keep the water temperature in a stable range. A filter can also be installed to slow down the deterioration of water quality.

2. Choose the right parent fish: After preparing the breeding environment, the breeder needs to choose several mature parent fish, so that they can reproduce better.

3. Provide adequate nutrition: After guppies are pregnant, breeders need to provide them with adequate nutrition, so that guppies can develop faster and small fish in guppies can develop better.
