Fish nightmare!

SO after seeing the babies I called my dad to ask if Molly fish, the kind we have, will eat their babies. He didn't know but I went online. Apparently they can, they don't always but they sometimes do. So We removed them from the tank for now.....but another fun fact. Mollies can have fish every 30 days. So do I eat them eat their young or do I take them out. Do I try and figure out which are males and females and separate them. I thought fish would be better then other pets. Maybe not.
