I didnt think I was a breeder....

In doing even more research I find time and again that the only livebearers that can interbreed are Endler's with guppies and platys with swords excluding certain pike species. If anyone has anything other than anecdotal evidence, please point me to it so I can study it. Thanks.

EDIT: Rohn and I hijacked this. I am erasing my further posts. I still ask that if anyone has specific references to platies and guppies interbreeding, please point me in that direction. No, not donkies and horses, just platy X guppy is all I am interested in. As I have stated all along, certain fish interbreed and as far as I know, platies and guppies are not two of them but being a fan of livebearing fish and somewhat of an eternal student, I want to learn if this has truly been documented. Thanks.

As for wondering how many babies have been born. Well there is always a chance that the babies were being eaten as they were born and that only a few were making it.
 
Cross breeding example with family of species such as between horse and donkey resulting in mule is not "anecdotal evidence" but a fact.

Try a google search for cross breeding there are number of articles.

Do you agree that cross breeding within family of species (not just species)? Mule as your classic example, the rest should be logical deduction. Then I don't need examples prove my point.
Classic example. Do you agree with Einstein Theory of Relativity. Then give me an example of time dilation. Something that is theoritcal proven today using astrophysics.

Sorry I give up.
Cannot convince someone that has already made up their mind.
Follow logical deduction, it is a common practice in every field of science.

I got one word,
Blood Parrot Fish

Well, now I know you're a troll. If you research you'll find it's a rare, manmade exception and that all Cichlidae cannot interbreed.

Thanks for the complimant.
You ask for an example of fish cross breeding , and you got it. And now you want an example in liverbearer family. Just because we haven't being able to cross breed other cichlids (or other fish within a family of species) doesn't mean it cannot be done. Genetically we know it possible, thus the parrot fish. The genetic makeup of all cichlids are simillar (keep in mind not identical), thus cross breeding beomes a possibility.

A few minutes a go you were adamant that cross breeding is science fiction in fish. Now it becomes "rare" when provided with an example. Please make up your mind.

Science is the ability to deduce from general fact. If this wasn't the case we will still be living in caves.

Now you want proof that cross breeding happened in this instance?
Correct me if I am wrong both cichlids and livebearers are fish. You can deduce the rest.
If you are looking for scientific proof in this particular case (livebearers) you might have to wait a bit ... require money, time and dedication to prove that. But cross breeding have being proven in fishes, mices, plants, microbes and few others; and have benefited mankind.. They all have one thing in common ... living creature with basic cell structure (not identical).

It is very easy to prove something wrong, yet it is very hard to prove something to be true. You can have guppies and platies in the tank and never have babies and say you have proof that they don't breed; But on the other hand if you have them in the same tank and they do have babies that isn't solid proof that they can interbreed. Just because it hasen't been documented by a science dosnt mean it's not possable.
 
Platies (genus Xiphophorus) and Guppies (genus Poecilia ) both belong to the family Poeciliidae. These are two closely related genera. Intergeneric hybridization does occur, in both plants and animals (including fish), so if one really wants to look at this scientifically than we can't conclude that Platies and Guppies cannot hybridize. We can show evidence that something does occur, but you can't prove that something doesn't occur. To the best of my knowledge there has never been a hybridization of Xiphophorus and Poecilia, but that is no evidence to suggest that it cannot occur.

Do I think that the fish that started this debate might indeed be a hybrid of Xiphophorus and Poecilia?
No.

Do I think that such a thing is impossible?
No.
