I've always been a fan of immaculate, clean, bare bottom tanks with overkill on filtration. Although too plain and boring for most my goal is to give the occupants of any aquarium I do the healthiest environment possible. Decor along with substrate are magnets for trapping uneaten food and waste. I've always found it much easier to keep all the tanks levels consistent and healthy by doing this. With High grade Discus this is very important since they are so prone to disease when Ph or other dangers begin to fluctuate. Most of these Discus have spent their entire lives in these type's of tanks. I applaud those who try to replicate a natural environment for their fish but in reality they are still in a cage with walls. Imo the most important thing you can do for them is give them the healthiest aquarium possible. You will be rewarded with healthy, robust, and colorful fish by doing so.
