1. Too much water change: The premature birth of guppy may be caused by too much water change, although they usually have low requirements for the environment. But after pregnancy, they are sensitive to environmental changes. If the breeder changes too much water for them, it may cause premature birth. In addition, when changing water, the water flow is too large, which accidentally impacts their abdomen, and premature birth may also occur.

2, frightened: The premature birth of guppies may also be caused by being frightened, and they are less daring. Especially after pregnancy, they are sensitive to the changes around them. If there is a loud sound around them, it may lead to premature birth.

3, being chased by male fish: The premature birth of guppies may also be caused by being chased by male fish in the fish tank. If there are too many male fish in the fish tank, they will constantly chase the female fish and try to mate, which will easily lead to their premature birth.

If guppies give birth to small fish prematurely, they can survive as long as they are carefully reared. Because they have become small fry, although they are born prematurely and have weak constitution, they can survive as long as they can be carefully cultivated.

If guppies are born prematurely and produce eggs, they cannot survive. Because guppy eggs develop in the body, they can't survive even if the surrounding environment is comfortable.
