No, Its not possible for a female guppy fish to get pregnant on its own. Although it’s an interesting fact that a female guppy can go through multiple pregnancies in succession after the initial breeding.
Female Guppy Fish has the ability to store extra sperm packets from the male, so it’s possible for her to give birth about once a month for up to 8 months after the birth of the first set of fry.
Each delivery is also known as a drop. So one can achieve multiple drops simply from one breeding session.
