Many of the most healthy, natural tanks out there have deep, rich substrate beds for the purpose of getting that anoxic enviroment (yes even in heavily planted tanks, it won't out compete the plants for nitrate). Whereas discus breeders stick fish in the most hideous, artificial, nasty looking tanks imaginable and have pride that they lay eggs on their breeding cones. They go with bare bottoms so they can vacuum up waste more easily, because they have no plants, no shrimp, no scuds, no live substrate, nothing to handle it. Their focus on simplfying the process has steralized the fun out of fishkeeping. I have far more respect for people who keep healthy tanks than people who have bred discus in tiny empty boxes.
