They should do a breeder handler things with fish. I breed the fish and give them to someone that wants to pay to show them. As long as I the breeder gets credit for being the breeders let the Fish handler get some credit for picking out a good fish to show. HAHA Just a crazy Idea I came up with.
Personally I would love to have a show betta. It stinks that you have to breed it yourself though. Of course I understand that because at the end they hold auctions, so its a way to build reputation for the breeders. Hey, thats an idea. You could always attend a show yourself and then buy one at the auction end? :D
if you do go into the shows with a show betta I think maybe you need to breed your own and hope for the best that the fish is in the right catagories, shape, and whatever else you need to follow in order to even qualify as a competitor but like I said your best bet is to breed babies and hope that one is the best
