Guppy belong to viviparous fish. Caviar is fertilized in the body of the female; fully formed fry leave it, immediately starting to take food.
Sexual maturity reaches 3-6 months.
Selected manufacturers are placed in one aquarium for 10 to 15 days. Pregnancy 5 – 6 weeks. One fertilization is enough to get several litters.
The number of fry in the litter depends on the quality and age of the female and ranges from 10 to 150 pieces. A sign of the approach of labor is the shape of the abdomen, which becomes rectangular and the appearance of a dark spot at the anus.
The female sweeps fry, which immediately begin to swim and eat. For feeding juvenile guppies, you can use any feed that is suitable in size.
Given that the fry are not born small, there are no problems. To obtain high-quality copies of food, there should be a variety of food, and in a nursery aquarium you need to keep it clean and periodically change some of the water.
When growing fry guppy There is another feature. Young fishes grow long enough, but a young male who has reached puberty and stained almost ceases to grow. The higher the water temperature, the faster the males mature.
