The small fish delivered by caesarean section of guppy may or may not survive, but whether it can live depends on the time of caesarean section. If they have reached the time of birth, it is possible that guppies will survive after caesarean section by breeders. If the guppies are delivered by caesarean section before they are mature, half of them will not survive even if they can be safely removed. Because the eggs need to be in the female fish to mature, the external environment is not suitable for their development, so the immature small fish cannot survive.

1. Dystocia: When guppy needs caesarean section for a long time, breeders need to give them caesarean section. Because dystocia lasts for a long time, both female fish and small fish may die at the same time, so breeders need to take caesarean section to take out small fish. If female fish still have the strength and energy to give birth, breeders should try not to give them caesarean section.

2. Death: If guppies die during production, the breeder needs to give them a caesarean section immediately, which can also rescue the small fish in the abdomen of the female fish. If the death time is relatively long, there is no need for caesarean section. Because the death time is too long, the small fish in the body will also die because of lack of oxygen.
