guppies? Guppies are fertilized in vivo. If people who have raised guppies look carefully, they will find that when the female guppies are pregnant, their anal and pelvic fins will appear black triangular color blocks. The guppy can be said to be a particularly fertile fish, and its annual production is also very large, basically every month. When the fish is in heat, the male connects the copulatory organ to the cloaca of the female and then discharges sperm for fertilization. The average time for a female to become pregnant is four to six weeks.
are the breeding conditions of guppies? Besides the water temperature of 20 to 28 degrees, the breeding conditions of guppies also need the acidity and alkalinity of water and oxygen. The breeding of guppies requires the acidity and alkalinity of water to be 6.8 to 7.4, so when raising guppies, we must put some aquatic plants in the fish tank, because aquatic plants can carry out photosynthesis and increase the oxygen content of water.
When guppies breed, it's better to change to a bigger tank so that they can move more freely. In addition, the reproductive conditions of guppies can not be separated from the sexual maturity of guppies themselves. Usually, the sexual function of newborn fish will mature after three to four months, when they have the ability to reproduce the next generation.
