Just wanting to breed a fish to create something new, or just wanting to breed a fish for the fun of it would be considered as backyard breeder on my list.
Being a true breeder, you need to know exactly what you are looking for and exactly what your trying to picture out of from the pair you have. You are trying to create something that would come out great, or create something that you would keep the frys. Grow them out and then cross them with something else to create something else new. It's all about picturing the future of how the fish will be. And lots of em'.
