hello-heres a funny question,my male guppys are always trying to mate with my female swordtails,could this actualy happen, and should i be worried ? many thanks
My old (ancient, actually) Innes book has pictures of what is claimed to be a guppy/molly hybrid. I don't know if that was ever proven or disproven. Too bad they didn't have DNA analysis back then...
Guppies and mollies can breed. Just like platies and swordtails can breed. (though molly X guppy crosses are more fragile) However, a guppy and a swordtail won't manage to produce any viable fry so don't worry about it
