Can Mollies breed with platies?

fletch

I think its possible to breed any similar sized live bearers. so saying that, pretty much anything apart from mosquito fish

You can interbreed swordtils, mollies, platies and guppies

If you have, say, 2 male Mollies and 2 female Platies, the question is how to make them not breed!

fletch

they probably wont but they can. Why wouldnt you want to interbreed them?

DEADFISH

as you were saying they can be interbread....how do they turn out?

I've been told by a scientist that they cannot interbreed.

Semantic Drift

Here's something I read on the Wikipedia entry for X. maculatus - "The fish commonly sold in pet shops is not a pure strain of X. maculatus, but is a hybrid between X. helleri and X. maculatus. In general if the male has a sword shaped tail they are called swordtails. Otherwise they are labeled platy. Color and fin shape vary wildly in the aquarium trade."

So, apparently, platys and swordtails can hybridize. I read some other sources, not as reputable as Wikipedia (if that's possible) that other livebearers can interbreed too.
