the picture i attached was of a males.The only issue i see with the green molly theory is that Muppy has a larger stomach then a normal molly, more guppylike then mollylike. See the pics i gathered, it shows a female guppy, a molly, and my Muppy. Looks like Muppy is a cross between the two, from the stomach to tail ratio(big words, ah!) It all depends on how old a molly has to be before they can mate. The male died about 3 weeks ago, so Muppy would have been about a month old by then, but still smaller then the other 2 adult females in the tank. So, anyone know how old a muppy has to be before it can breed?
here's a picture of a pregnant female molly.
