How many days do guppies give birth?

Guppies give birth over two or three days. First-time mothers usually give birth to 12 to 30 fry within several hours, but veterans can produce up to 80 fry and take up to 48 hours to deliver them all.

Monitor your birthing guppies for 48 hours to see if they’re still delivering more fry or not. Ensure the mothers are stress-free and well-fed during the birthing period to keep them happy and healthy.

After your guppy finishes giving birth, you can expect another litter in 30 days. This is because female guppies can store sperm for up to a year and can get pregnant again right after giving birth.
