cross-breeding

[peanutPUNK]

has any one cross breed a fish?( besides flower horns and parrots)

Flowhorns and parrots are actually not crossbreeds, they are engineered (test tube fish for lack of a better word) of species that would never normally breed.

Maybe I'm wrong about this, but I am absolutely convinced that that is a myth. I have a fish that is a midas-blood parrot hybrid (yes, a hybrid of a hybrid, lol) and it would very much like to spawn with my oscar... talk about an unlikely pair!!
Normally, yes, a red devil would tear a severum to pieces, but if they're raised together and form a pair I'm convinced that they could and would spawn. That's a much more likely scenario, I believe, than test-tube babies
My hybrid is a very ill-tempered little lady, but like I said, she is very fond of my oscar and aggression is almost non-existent because of their pair bond.

yes I agree with synirr on this one, on many of the boards that I go to for cichlids I am seeing more and more posts about their midas, or RD or what ever pairing off with a bp and having eggs and then fry. I have heard of JDs and GTs having fry, so this whole situation would end up being entirely possible.

what about parrots not breeding? this should have too be engineered it's not exactly a natural evolution to create something that cannot reproduce

 

[freddyk]

I'm not saying cichlids can't cross, I'm saying those two types were not made by simply breeding two together. Too many cichlids can cross unfortunately, though most create something fairly ugly, which is why they go through the trouble of engineering the common 'hybrids'.

How about mules? Horse+Donkey=Mule Which are infertile. Its not that uncommon. They will mate even though there diffrent species.

I will put this out there as a bit of mind fodder. I personally think that there is a difference between cross breeding and hybirdization. I will use cichlids as my examples as that is what I am most fimilar with.

you go to the lfs and see a midas for sale, chances are that it is a mutt, a midasxred devil cross breed, 2 totally different species, but they belong to the same group, amphilious. where as BPs are a hybird of god knows what since the scientists that make FHs and BPs never totally disclosed the parent species.

A hybrid is any animal which is the offspring of interbreeding between two different species, period. Those midas/RD mixes are indeed technically hybrids. I have to point this out because I am a biology student and completely anal about that kind of thing.
Also, by "scientists," I'm assuming you mean Tainwanese breeders

freddyk -- If they can be made by artificially mixing egg and sperm from two seperate species, they can be made "the old-fashioned way." Severum and midas/RD spawing behaviours are sufficiently similar that I would consider them breeding naturally well within the realm of possibility when there are no other, more preferable choices of a mate in their tank. I mean hell, if my midas hybrid would pair up with an oscar of all things, anything is possible. So long as the midas/RD has not established itself as the dominant fish, as is the case in my tank, it will assume submissive behaviour and be relatively peaceful, hence allowing a pair bold to form.

vantgE -- "Natural evolution" has nothing to do with it, but neither, I think, does any kind of complex engineering. Hybrid animals are very often infertile. As wwestar2000 pointed out, mules would be a good example of this. Another example would by ligers, which are hybrids of lions and tigers (yes, they do exist outside the realm of Napoleon Dynamite, lol.) Animals, given the option of a mating with their own species, will almost always choose to do so. However, when we humans combine them with other closely-related species and give them no other alternative, they will hybridize. The instinct to reproduce is quite strong, you know
As chance would have it, female bloodparrots are not infertile, but the vast majority of males are. This can result in fish like my Marie Antoinette, who is a midas/sweetheart (tailless) BP hybrid.
