Hi there, I am a newbie and this is my first post. I have recently bought 5 female guppies and they are all pregnant. I have put them into a tank on thier own. How do I know when they will give birth, what should I look for. Is there a chance that they will abort because of the change in tanks (from pet shop to me). Please help and give me as much info as I need as I really want to be successful. My grandchildren are so excited and they cant wait to see some baby fish. Thank you all, Lee
