Guppies do not necessarily defecate in large quantities before giving birth to small fish. The coarse stool of guppy may also be caused by eating a lot of food. Guppies will have anal eversion, belly enlargement and fetal spot color deepening before giving birth to small fish. If these situations happen at the same time, it means that guppies are going to have small fish.

Some guppies pull coarse stool when making small fish. Some don't, they only defecate normally, and some guppies don't defecate when they give birth to small fish.

1. Water temperature: guppies are tropical fish, and the water temperature can be maintained between 22 degrees and 26 degrees at ordinary times. When small fish are born, the water temperature can be slightly raised and controlled at about 24 degrees, which is beneficial to production.

2. Environment: Guppy is easy to be disturbed when giving birth to small fish, so it is necessary to arrange the environment before giving birth to small fish. Ensure that the production environment is free of light and noise.

3. Feeding: The guppy does not need to be fed when it is raw. The food can be prepared and fed to the guppy after production.

4. Isolation: After guppies give birth to small fish, they need to be isolated from small fish. Because guppies are hungry after production, they may swallow small fish.
