Hi Krystal I assume you already know a bit about your guppies - e.g. they are livebearing (viviparous) with the male using a modified anal fin (gonopodium) to inseminate the female. Female guppies are indeed able to store sperm (in an organ called the spermatheca), and can produce up to 8 broods of young from a single insemination. The gestational period is about four weeks for most livebearing species, including the common aquarium species and females can store sperm for several months - so she may well have more births yet! I hope that answers your question Dr Dave Hubble Southampton UK
