I can't really answer the question, Cory_Dad. I am inclined myself not to further the line. I don't mix my farm pandas with my breeders, although they may have contibuted to my recent long fin panda spawns. I will separate those fry and most likely take them to the lps.
That would be a good question for the Big Dogs, and I would be interested in the answer.
Just as a guess, I am inclined to believe that serious breeders would not want to use them or buy them for breeding purposes. The genetics would be questioned.
For my own tanks I would be willing to keep the fry for tropical communities. I might take them to the lps. But I would not offer them on Aqua Bid, for instance. When I buy on AB I want quality fish for breeding. I want bonefides. If I sell a Cory I want to be able to say what it is and how it was bred. When I sell my longipinnus, I want to know that I am selling F1 or F2 fish that are what I say they are.
I have lps peppers, aeneus and sterbai. They all breed, but I would not sell any of them on AB. I would sell them for a community tank or to the LPS and do add them to my non breeding tanks.
There is always the suspicion of hormone inducements and inbreeding, which are suggested to increase genetic problems.
Cory folk for the most part don't approve of hybrids and line breeding.
