There's a flowerhorn community that differs somewhat from the regular cichlid community.
There are no shortage of people keeping and breeding bad quality flowerhorns. Way fewer actually doing it well. Developing and refining new varieties takes a lot of time, effort, culling and really good base stock. Same with any "fancy" fish: Stendker discus varieties don't come about randomly...nor do desirable fancy guppies, bettas, angelfish, etc.
There's an amazing store in Sacramento, CA that's run by Malaysian guys who get legit flowerhorns. The store is full of trophies of competitions in Asia. They also specialize in fancy discus. Some of the best aquarists I've ever met. They just choose to focus on flowerhorns and rainbow discus vs. little brown fish
Check out some of the flowerhorn forums and you'll find some great folks on the east coast (and around the world)...
