Do Livebearers Crossbreed When Mixxed?

[Joller]

i have guppies and mollies(currently in separate tanks), would they definitely cross breed given the chance? or are the chances low when theirs large groups of both fish mixxed?
also when do guppies and mollies reach sexual maturity because i don't want my molly fry to impregnate my guppies
thanks

Crosses are very difficult to produce. The fry tend to be very weak so rearing them is hard.
I would not worry about it unless your rarely wanting to do so.

well i've read that if a male molly impregnates a female guppy it would cause her to die, thats what worries me

Although it is theoretically possible to cross guppies and mollies, we simply do not see it happen in a typical aquarium Joller.
