All of the fry were deformed in some way, and all died within the first 2 weeks except for 1 which I still have. The one that I do have is blind in its left eye. It looks kind of odd. Imagine a fat guppy (I bred a balloon molly with a fancy guppy) with black streaks all over its tail. This is the best picture I could get of it.
I think it looks like what he says it is maybe he did have a virgin its possible i think it could happen a had a community tank that the male guppies had relations with my female platies but never saved any babies becuese had danios that ate them all but i bet that some of the babies were hybrids so i believe himSadieDee;1463177; said:You can't cross a molly and guppy, it's not possible. The reason the fry were deformed (I'm assuming the female was the molly) was the fact that it was a Balloon Molly and Balloon Mollies are already "deformed" (they have a shortened spine that gives them the balloon appearance). Livebearers also store sperm so you can't guarantee there was even a cross unless you had a "virgin" fish. When you go to a fish store, 99.9% of the females are already pregnant and it can take months before they use up all of the stored sperm.
