I like Katt response...it sums up how I feel.
I basically have some herps that will NEVER go anywhere if I can help it. They are like kids, and we love them each for different reasons. They are part of my "collection" as well if you can call it that. And some I will breed, some I will just keep because they needed a home, or because I liked them.
But I have other herps that I have because I have a specific interest in them. I LOVE my corns but they are my interest and I have traded a female before because she had beautiful coloration, some interesting genes, and she would make someone else really happy....in a place where that person has a male to suit her right. I did not, so I found that place for her and got a male in return who would suit my plans better. Both homes (mine and the persons) were excellent and I see nothing wrong with it.
