guppies wait for 4-6 weeks to give birth to small fish, but the specific production time depends on their living environment and feeding methods. If the water temperature and quality in which they live are stable, and the breeder can provide them with sufficient food and nutrition, the small fish will develop faster in the mother's body, and the waiting time will be shorter, generally only 4 weeks to mature. When they live in a poor or unstable environment, their waiting time for labor will be longer, and it will take about 6 weeks to mature.

The production time of guppies is not fixed. As long as they live in a comfortable environment, they can reproduce normally. The amount and frequency of their reproduction are relatively high compared with other fish. Generally, they can breed once a month and 11 times a year. Although they can reproduce more times, breeders should try not to let them reproduce too many times. Because the frequency of reproduction is too high, it will not only affect their physique, but also affect their life span. Under normal feeding, guppies are best produced 5-6 times a year.
