Platy can get to 2 - 2 1/2 inches long. They are livebearers, so the fry come out swimming. If you leave the fry in the tank, chances are you will only get 1 or 2 out of 30+ that survive. The rest, most likely will get eaten by anything in the tank (even their parents!) If you have another tank that you want to use to grow them out, and you can catch them soon after birth you can, but remember that they eventually could get to be 2 inches, so you need to make sure that you have a proper home to put them in once they are big enough to leave the fry tank.
