The guppy will give birth when its belly is black for about 2-4 days, and the black belly of guppy is a relatively obvious symptom after pregnancy. When guppies are pregnant, they will have a fetal spot on their abdomen. But at this time, the fetal spot color is not deep and not obvious. But as their bellies get bigger and they become pregnant longer, the fetal spots will become darker and darker. If the tyre spot turns black, it means that they will start to produce. So after breeders find that the guppy's belly turns black, it will start producing in a few days.
2. What should we pay attention to in guppy production1. The environment is stable: guppy is sensitive in production, so it is best for breeders to keep the water temperature at about 25 ℃. If conditions permit, it is best to install a heating rod to keep the water temperature constant. A filter can also be installed to slow down the deterioration of water quality.
2. Quiet environment: Guppies are easily frightened when they are produced. Breeders need to keep the surrounding environment quiet and try not to make too much noise or change.
3. Dystocia: Guppies are oviparous fish, which are prone to dystocia during production. Breeders should pay attention to careful observation to avoid dystocia of guppy. When it is found that guppy is in dystocia, the breeder needs to deal with it immediately to avoid harm to the parent fish.
