pregnant guppys

Question
hi,i have a pregnant guppy and i dont know how long it takes to give birth since it mated

Answer
Hi Aaron,
 Here's the really cool thing:  after a guppy mates, she stores the sperm and can continue to use sperm from that mating for a long time (months, possibly longer).  So, it could be any amount of time after mating.  Typically once she starts to look pregnant (round and fat) it will be a matter of a couple of weeks before she gives birth.
