Can you give some more specific on how you got them to breed? Tank size, how much water, temp, foods, a picture would be awesome to show the setup if you can get one. This owuld help others to get an idea of how to do this.
As for breeding them from a LFS, these strains come from better genes and if you can keep the genes new and not inbreed then you should see the better colors and fin shapes start to come out. It would mean culling some if you can't sell them but getting the better strains and nicer fish is good for the hobby and hopefully could lead to better fish in more locations. Just MHO.
