What I described were shows put on by ACA, OCA, NEC and many other national organizations. They don't expect people to load their entire tank in a car and drive 100's of miles. Thus the shows I go to have just one single fish in each tank. I do know that local clubs do have some classes that you mention but they are extremely difficult to set up for just 2 or 3 days. Our local club does have one "Tank Beautiful" class similar to those you mention BUT and that's a big BUT!, I have found that most times people who set up an entire landscaped tank find it takes almost 2 days for the tank to settle down and clear up. By that time the displays have been judged and those that are still cloudy are out of contention. This is just another aspect of the aquarium hobby and there are many people into it but it is very difficult. I suggest you enter a tank at a local show and see how all the 'old pro's' do it. You will learn a lot from the experience and meet a lot of new people. It's fun but you must be dedicated to showing. I haven't shown (single fish) in a few years because it is very time consuming. As I stated, try it, you may really enjoy it.
