If I enter a tank that competes with yours, and yours wins because I obviously suck at aquascaping...
Anyway...I would want to do my best to set up a tank prior to the next competition and pit it against yours.
Keeping with the athletics theme...Matt Biondi and Alexander Popov or Pete Sampras and Andre Agassi. Eventually the champion is going to lose. I want to be the one that brings him down.
