I understand what you are saying but I only have one Female Dalmation Molly and one Male Platy and I put the Dalmation molly in the maternity wing when she got fat .. it’s definitely a cross breedWelcome to the forum!
I'm sorry to say, but platies and mollies could never naturally crossbreed. Its kind of the same as trying to breed platies in guppies, it will never happen. They are not close enough related to do that. That's a normal platy coloring and is defiantly just a platy. Im guessing you have a platy female in there, and she gave birth to it.
