yeah, my female guppy loved getting knocked up. I don't know how many babies she had because they were overnight, and left in the tank with the rest of the fish, I think there were 3 or 4 in the morning. Well not only did she pop out xx babies overnight, but then I seperated her, and she had 3-4 babies EVERY NIGHT for a month straight. I sent her back to the store. I think a few here and there, fine, but it was getting absure. And yes, I eventually put them and her all back in the main tank and let nature take its course. Really noone chased them or hunted them, saw the most casualties go by accident when the mom was eating. She got huge, maybe 3-4" long and about the girth of a hot-dog. She would be some breeders star guppy.

GL with the babies and new tank.
