Re: Swords & Molleys
I wouldn't worry Sandy...Mollies and Swordtails will not crossbreed with each other.
The only livebearers that do are: Platies will crossbreed with Swordtails. Endlers Livebearers will crossbreed with guppies. Mollies will crossbreed with other Molly types/strains (such as your sailfin Molly and balloon Molly etc.). Guppies and Mollies can sometimes crossbreed but the fry (if any) are either sterile or usually don't survive very long.
There are so many different colour morphs out there now that get passed on through the genes, that the fry can have different colour markings to the parents.
