I find discus THE most beautiful and exotic fresh water fish. And yes, you are correct about its habbitat requirement... water must be kept at 28C, slightly low in pH and soft. Speaking of plants, I always wanted to have a fully planted aquarium but in the case of having discus fish i don't think there will be any plants at all. First of all, it is very difficult to find plants that would live in 28 degree water and second, if I find, it would make it more difficult to take care of the system.
I am in a process of buying a condo right across Case so once i get my fish tank all set up, you are wellcome to drop by and take a look
What fish do you want to get?
