This is the most FAQ's by the experienced livebearer breeders, and unfortunately the answer is "Negative!" Not all of them can be crossed. They will only breed within their own species, although some of the same genus will be genetically not compatible and will not breed.
Genus: Mollies – Poecilia Latipinna Guppies – Poecilia Reticulata Endler’s – Poecilia sp. Endler's
Swordtails – Xiphophorus helleri Platies - Xiphophorus maculatus Variable Platy – Xiphophorus variatus
Platies, Variable Platies , and swordtail are so very closely related that they will often breed resulting to many color varieties of xiphophorus that we enjoyed.
Mollies and Guppies are not that common crossed, but there are some rumor that they do successfully crossed them, but they tend to be sterile and eventually dies at young age.
Endler’s and Guppies are so very closely related that they will often breed resulting to many color varieties available at the local fish store (LFS). Note: Before buying endler’s make sure that it is really an endler’s not just a feeder guppies.
There are documented cases of Common Guppy males impregnating Molly females. Pictures were published in Dr. Axelrod's "Encyclopedia of Aquarium Fishes." They proved to be infertile and developed tumors as they matured and subsequently died.
