cross breeding?

i've heard a lot about crossbreeding with guppies mollies platies and swordtails. some people think that it shouldnt be done because it ruins the pure strains of the fish. i personally think that it would be okay to crossbreed for your own tank but they shouldnt be returned to the store. i have also heard that if you cross breed the fry will be infertile. is that true?

Cross breeding has it's places. In the home aquaria where the fish won't be sold is one of them. If you really want to have some fun with cross breeding then do it right. Cross breed the species, keep genetic records and do it right so when you are done you can introduce a new species.

After all, how cool would it be to have a tiger striped Platty! Just make sure that the breed you come up with doesn't have any major genetic throw backs. Last thing we need is another fish that can't close it's mouth and has to work 10x harder just to swim because it's fins are too small. Parrot fish are cool and all but they deserve better.

i agree completely. make sure when and if you cross breed that you dont create physical problems in the fish. they never did anything to you.

that sums it up nicely, and if we dont cross breed sometimes, possibly some species may get old

The first rule of Fight Club is - you do not talk about Fight Club. The second rule of Fight Club is - you DO NOT talk about Fight Club. Third rule of Fight Club, someone yells Stop!, goes limp, taps out, the fight is over. Fourth rule, only two guys to a fight. Fifth rule, one fight at a time, fellas. Sixth rule, no shirt, no shoes. Seventh rule, fights will go on as long as they have to. And the eighth and final rule, if this is your first night at Fight Club, you have to fight.

I'm of the opinion that we dont need anything new. There are plenty of natural species already available.

That being said, I don't have a problem with it as such, as long as the fish are not deformed in any way, and resulting fry are kept at home rather than sold to a lfs until much more is know and documented about them.

The main problem is when the fish gtet back in the LFS, are sold in Auctions or local fish swaps. Some keepers thing theymight have a fish that is a pure strain but have not bred out the majority of the other fish genes or just don't care. Is like breeding dogs, cats or anything else. I know a lot of breeders that won't even depend on pedige papers for dogs but insist on blood tests and geneology before they will breed prize specimens.

Now with fish like sords, platties, guppies and others, there is very little attempt to keep any strains pure except by the most disciplined keepers. In all actuality I have never bought two live bearers that looked almost identical that didn't have many different colors of offspring telling me they were actually cross breeds slapped with a lable. For live bearers I guess this ok but do we want all of our fish to suddenly become "mutts" with the rarest exception of a pure breed?

yeah, if we sell the mutts to a store, that, to me, isnt a good idea as they may be very aggresive to other fish besides themselves, overeat and make the other fish starve, and problems like that. i think in the home aquari crossbreeding is fine, but with the occasional exception i think that if certain fish is sold to stores and are definitely safe to keep, i think go for it.
