My pregnant guppy

Question
I got my guppy just the other day and the women said that she is pregnant. She said that i should put it in the breeding tank when i got home and i did. But i don't want to leave her in there for a long time. I don't know what to do! Could you please help me?

Answer
Ok if the guppie is pregnant you will see a black dot on her stomach and when it gets a good size she will have the babies. Also the babies need a heated tank or else they will just die. You are going to need fry food to feed the babies that should be at any petstore.
