I like the interactive nature of discus. When you come into the room they come over to the side of tank to see what you are up to. They are peaceful, slow moving, and give a serene quality to the room. Even less than ideal specimens (as mine are) are remarkable and unique in both shape and color compared to other fresh and even saltwater fish.
I enjoy knowing that I've created an environment all of my own making that supports and generates life.
My discus won't be bred, unless I decide I like my fish more than I like my wife...
