Abdominal squareness: The abdomen of guppies will be squareness before production, because they are viviparous and have larger stomachs. Near the time of delivery, the abdomen will become square. Deeper fetal spots: when the color of the fetal spots of guppies turns black or dark brown, it means that they are going to give birth. The darker the fetal spots, the closer they are to the date of production. Protrusion of anus: when the peacock fish is about to give birth, the anus will be prominent. First, what kind of peacock fish is going to give birth 1, abdominal variation: peacock fish is ovoviviparous, and small fish will be born only after it matures in the mother. When guppies are pregnant, their bellies will become round. But when their bellies become square, it means that they are about to give birth.

2, the fetal spots become darker: when the color of the fetal spots of guppies becomes darker and darker, it means that they are about to give birth. When the color of tire spots turns black or dark brown, it means that production is about to start.

3, anal protrusion: the peacock fish anus becomes more prominent, which means that they are going to give birth. There are also some guppies whose swimming speed will be affected, and some will quietly hide at the bottom of the tank to give birth.

Second, how long does it take for guppy to give birth? It takes 3- 10 hours for guppy to give birth. As mentioned above, they are oviparous fish, so the production time will be longer. Under normal circumstances, they only need 3-4 months to be produced. But if it is the first time to produce guppies, it will take longer, about 5 hours. Although they take a long time to produce, the longest time will not exceed 10 hour. If the guppy hasn't been produced for more than 10 hour, it may be dystocia, and the breeder needs artificial stimulation or midwifery to help them produce the small fish quickly.
