As of right now my 25 gallon tank has 3 platy's (1 male and 2 female) and 2 peppered cory's. My first question is, can platy's share a tank with guppies? If so, how many of each can I get away with in my 25 gallon? If they cant go together, do you think 10 to 15 platy's is too much for my tank? I know both guppies and platy's breed like crazy and that is what I am hoping for.
