I didnt think I was a breeder....

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.
Well put.

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

this argument has gone crazy... from what ive read, harlock is saying that it physically isn't possible because of how the guppy is made compared to the platy. Rohnds also makes a point on how the genetics are similar enough that if you were able to artificially mix the genes of the two species together then it would be possible to get a cross breed, but considering that this would result in an infertile fish and that it would also take lots of scientific stuff to perform, it could never occur in an aquarium.

yes it is tecnically impossible to disprove anything bsed on the logic that ive heard in this thread, but there HAS to be truth, so this way of thinking is futile... you sound like a bunch of stoics!
 
sorry didn't mean to use the word "impossible" and yea the point of the whole topic was left behind long ago...
 
ok, so i didnt read all of the posts, but i still would like to see the fish in question, it sounds neat
 
Also, what started this whole thing was the original poster claiming that the fish that gave birth recently was a play/guppy cross.
Now I know why it is impossible to debate with you, you never read what I write.

This is what I wrote originally,
Both Palties, guppies and swordtails all belong to the same family of fishes, Poeciliidae. Thus their genetic make is simillar and not identical. So, cross bredding is possible except their offsprings would be sterile. That is unable to repoduce themselves.

Having said that, it is more than likely that either your platies or guppies came from the LFS pregnant.
These creature have a remarkable ability to store the sperm in their body till it is the right time to give birth. An ability some creature have that is vital to survival of their species.

Read carefully the reason given. I pointed that cross ibreeding s possible, that it produce sterile off spring and the more plausible answer being that they were either pregnant coming from the LFS or was carrying sperms in them.

i have a book on plat's and a book on swords, and they both seem to say that 99% of what you'll find at an LFS as far as either are concerned have a little of the other in their family tree. has nothing to do with any of the topics in this thread, but i thought i'd throw it in as a fun fact, heh.
 
Did harlock remove his posts? If so, why?

Whatever these fish are, I still need information related to what is going on. My platy/guppie/whatever has had one fry on Sunday night. I am now back home in VA and going by what my mom has been telling me but so far there are no other fry. Is it possible the other fry were eaten? Yes, of course.... but why is mommy still very large?

Regarding the new subject of this thread, I think that it is possible for cross-breeding. The platty (RIP) as in my one tank with fancy guppies for about 4 months before I moved her to another tank with tetras. It was about 2 weeks after moving her to this new tank that she had babies and died. This happened about 6 months ago so the "babies" are pretty grown and now the fry I have now are from one of these fish. This is where my concern is.... if these fish should be infertile why is mommy still big and only has had one fry.... is there a problem with this fish?

I am going to try my best to get some pictures for you. I will not be back in PA for another few weeks but I will see if someone up there can take some pics and send them to me -- they just arent really technically inclined.
 
It is also possible for platies (and other live bearers) to "hold" their babies in times of stress. This unfortunatly often leads to someone dying. Hopefully this is not the case.
 
yea, thats why some people have been saying that they can give birth even after months of not having a viable mate

i still wanna see pics, they sound interesting

pics pics pics

I didn;t remove all of my posts, just the ones that kept asking the same thing while the only answer I received was mule. The guppy and platy did not interbreed. Again, guppies and mollies might be able to and there is some very fuzzy evidence saying they might have. We know platy and swordtails crossbreed. We also know guppies and Endler's will crossbreed. Also, you need to note that any offspring from such a cross as platy X guppy would be sterile. So, what should be a sterile fish just gave birth. You have two conclusions to reach. One, she wasn't a guppy X platy (most logical as well as scientifically sound as I have seen no data to indicate guppy X platy in history). Two, you should name the fish Mary because it had to have been an immaculate conception. I'll let you pick.

So she was without a male of her species for four and a half months. They can store sperm for up to six months and or four pregnancies from all the literature I have read. Not so uncommon at all for her to become pregnant later, despite the lack of a male platy of swordtail around.

I've never said cross breeding of fish in general is impossible. It's very obvious from post #5 that I feel platies and swords do it. Again, I've never seen a documented case of platy X. guppy and all I ask is for someone to proide that evidence if it is there, as I love livebearers and would enjoy the read. As for only having one fry it is most likely others were born and as you didn;t see it happening, they were preyed upon by tankmates. There are usually very logical answers for most things, you just have to be willing to accept them.
