Live Guppy Birth aka Guppy Vending Machine

My daughter started off with 6 guppies and the females give birth every three weeks or so. Both males and females think the Mama is some kind of snack machine and approach the new babies like, "Oh look she just made food...I will eat it" Mama also enjoys some. We have since rescued 60 to 100 newborns to a new tank and possibly lost as many cuz MAN those hungry guppies be quick!
