Well….there seems to be more and more questions about hybridizing Livebearers these days. So here is some handy information that might help you out. There’s lots to think about, before you hybridize.
First off, the families of Livebearers! There are four families of Livebearers, not counting Stingrays.
Poeciliidae
These make up the largest family, with almost 200 species! They are called toothed carps because they have teeth on both the upper and lower jaw. The teeth are so tiny, though, that you need a microscope to see them. Toothed carps are the ones usually kept in aquariums. They originally came from the Americas, though their range extended from the North USA, to Argentina, in the south. Some of these fish feed primarily on mosquitoes and their larvae, however, scientists conceived the idea of using them to control the mosquito population biologically. Guppies and mosquito fish were introduced into the wild and swampy areas of Southeast Asia and the Philippines to keep marial mosquitoes in check. The fish spread to all sub-tropical and tropical waters, including the waters near southern Europe.
Goodeidae
These fish aren't commonly found in tanks. Only about 35 species of this live-bearer are known. They live in the rivers and lakes surrounding, and in the Mexican plateau, along with the rivers leading down to the Pacific Ocean, from the plateau.
Hemirhamphidae
They are easily distinguished from other live-bearers by their beak-like mouths, and straight pike-like bodies About 20 species are in this family. They live in both fresh and brackish water. They can be found from in India to Indonesia, also in the Philippines and Southeast Asia.
Anablepidae
This is the fourth family, and they are some of the most interesting fish you can keep. They have the amazing ability to see above and below water at the same time, thus the name four-eyed fish. Four-eyed fish generally live the in brackish water of mangrove swamps. They occasionally occur in pure saltwater too. These fish have been found living in freshwater, hundreds of miles inland, but they are usually found along the Atlantic coasts of Central and South America.
So now we know the families…but why is that important? Well, because, Livebearers MUST be in the same family to hybridize. They also have to be in the same genera. I did a small species list, color-coded to show you who can breed with who. However, it is only color-coded by family, since there are a limited amount of colors. . I have only done the most basic species here, basically the ones you will be able to get the easiest. If you all want me to add a whole list of Livebearers, I can do that, but I didn’t want you all to have trouble finding your fish. However, if you have just one or two fish you think should be added, just PM me.
Poeciliidae
Poecilia sphenops - Molly, Short-finned Molly
Poecilia latipinna - Sailfin Molly (Variation, Balloon Molly)
Poecilia velifera - Mexican Sailfin Molly, Yucatan Sailfin Molly, Green Molly, Sailfin Molly
Poecilia reticulata - Guppy, Feeder Guppy, Fancy Guppy
Poecilia sp. - Endlers Livebearer
Xiphophorus helleri - Swordtail
Xiphophorus maculatus - Platy
Xiphophorus Variatus - Variegated Platy, Variatus Platy
Gambusia affinis - Western Mosquito Fish (They technically can cross with Guppies, however they can be extremely aggressive, so this is one to be very careful with)
Heterandria Formosa - Dwarf Livebearer, Mosquito fish, Dwarf Top Minnow
Belonesox belizanus - Pike Livebearer
Hemirhamphidae
Nomorhamphus liemi liemi - “True†Celebes Halfbeak
Nomorhamphus ebrardtii - Orange finned Halfbeak (Often sold as Celebes Halfbeak)
Dermogenys pusilla - The Wrestling Halfbeak
Goodeidae
Ameca splendens - Butterfly Goodeid
Characodon lateralis - Rainbow Goodeid
Caracodon audax - Bold Caracodon or Black Prince
Xenotoca eiseni - Orange Tailed Goodeid
Anablepidae
Anableps anableps - Four-eyed Fish
The most common true hybrids, out of this list would be Platy/Swordtail, Guppy/Endler, and True Celebes Halfbeak/Orange-finned Halfbeak. However, please note, it is not guaranteed any two fish will breed. Some need to be genetically hybridized. Just because you put two fish of the same genera together does NOT mean they will breed. Also, please consider what you will do with the fry. Not all fish stores will take hybrids. And all the fry will need homes. I strongly urge you to think the whole thing through, a good few times, and then consider breeding. Also, please remember, just because you breed two different fish together, doesn’t mean you’ll get something spectacular. For example, Endler/Guppies just look like fancier Endlers, or sometimes not even different at all. Also, all color variations of the same fish will readily breed together, and are not considered hybrids.
Before you attempt to hybridize, after you’ve thought everything through, realize what the fry will need, have homes for them, etc., consider what the adult fish need. Do they need Brackish water? A huge tank? Well, here is my species list again, but with the needs of the fish. Just Max Size/Min. Tank Size/Fresh, Brackish, or Marine. Minimum tank size is the absolute minimum…bigger is better. Also, it depends on how many fish you keep, but you can use your common sense to figure out that more fish need a bigger tank.
Poeciliidae
Molly, Short-finned Molly (Poecilia sphenops) - 4"/15 gallon/Fresh
Sailfin Molly, Variation: Balloon Molly) (Poecilia latipinna) - 6â€/20 gallon/Fresh, Brackish (Can be acclimated to saltwater if done correctly)
Mexican Sailfin Molly, Yucatan Sailfin Molly, Green Molly, Sailfin Molly (Poecilia velifera) - 6"/20 gallon/Fresh
Guppy, Feeder Guppy, Fancy Guppy (Poecilia reticulata) - 2â€/5 Gallon/Fresh (Can take salt)
Endlers Livebearer (Poecilia sp.) - 2â€/5 gallon/ Fresh
Swordtail (Xiphophorus helleri) - 4†(7†including tail on males)/15 gallon/Fresh
Platy (Xiphophorus maculatus) - 2â€/10 gallon/Fresh (Can take salt)
Variegated Platy, Variatus Platy (Xiphophorus Variatus) - 3â€/10 gallon/Fresh
Western Mosquito Fish (Gambusia affinis) - 2.5â€/10 gallon/Fresh, (Sometimes found in Brackish waters)
Dwarf Livebearer, Mosquito fish, Dwarf Top Minnow (Heterandria Formosa) - 1â€/1 gallon/Fresh
Pike Livebearer (Belonesox belizanus) - 7.8â€/45 gallons/Fresh, Brackish
Hemirhamphidae
“True†Celebes Halfbeak (Nomorhamphus liemi liemi) - 4â€/20 gallons/Fresh
Orange finned Halfbeak (Nomorhamphus ebrardtii) - 3.5â€/20 gallons/Fresh
The Wrestling Halfbeak (Dermogenys pusilla) - 3â€/20 gallons/Fresh, Brackish
Goodeidae
Butterfly Goodeid (Ameca splendens) - 4.7â€/3’ Aquarium/Fresh
Rainbow Goodeid (Characodon lateralis) - 2â€/15 gallons/Fresh
Orange Tailed Goodeid (Xenotoca eiseni) - 3â€/20 gallon/Fresh
Anablepidae
Four-eyed Fish (Anableps anableps) - 12â€/55 Gallon/Brackish
Of course, before you put any fish together, look at their compatibility and their water needs. Research them. A lot. For some of these fish that can go Fresh/Brackish, or Brackish/Marine, find out how they were raised, then keep them in the same conditions. Research, research, research these fish before you get them! Most of these fish can be kept in community tanks, however, if you are trying to hybridize, I would consider a dedicated tank just for that. Also, if one fish you are trying to hybridize is bigger then the other, make the female that of the bigger species, so the smaller fish doesn’t have bigger then normal babies growing in her. This can lead to stress, birthing issues, and even death.
And last but not least, enjoy your fish, even if you decide not to hyrbidize. All fish are special, and pretty in their own way.

I've always wondered that.
