Unfortunately, Guppies (Poecilia) and Platies (Xiphophorus) cannot crossbreed. This is because both fish belong to different genera.

Can Guppies Crossbreed?

Yes, members of the Poecilia genus, which includes guppies, can crossbreed with each other. For example:

  • Guppies are Poecilia reticulata
  • Endlers are Poecilia wingei
  • Mollies are Poecilia sphenops

Thus, all of the above fish can interbreed. They all belong to the genus Poecilia.

Do Platies Crossbreed?

Yes, swordtails and platys are part of the genus Xiphophorus. Thus, the species can interbreed.

  • Platies are Xiphophorus maculatus
  • Swordtails are Xiphophorus helleri

However:

Platies that are Xiphophorus maculatus cannot interbreed with Guppies which are Poecilia reticulata and vice versa.

Lastly, keep in mind that these fish are prolific breeders and will try to mate with other live bearer fish in the tank (especially male guppies). But, there will be no fertilization and thus no fry from the attempt to mate.
