The delivery time of guppies varies depending on individual differences and the number of times they have given birth.
Longer First Delivery Time: Guppies giving birth for the first time usually take a longer time, generally about three to ten hours. This is because the fish egg embryos in the belly of a first-time mother guppy may not be fully developed, resulting in an extended delivery time.
Shorter Subsequent Delivery Times: As the number of deliveries increases, the delivery time of guppies gradually shortens. Usually, subsequent deliveries may be completed within half an hour to twelve hours. However, guppies that are disturbed or frightened may have an extended labor time.
Factors Affecting Delivery Time: The delivery time of guppies is also influenced by their physical condition. For example, guppies in good physical condition may have a shorter delivery time, while those in poor physical condition may take longer.
Pregnancy to Birth Cycle: The pregnancy cycle of guppies is approximately 21 - 28 days, and the specific time depends on the environmental temperature and nutritional status. During pregnancy, you can judge whether a guppy is about to give birth by observing the changes in its abdomen and the color of the gravid spot.
