Well discus are the farthest thing from a freshwater beginer fish as you can get. The cost and mantenance compares to a marine tank. You must provide very stable conditions, and at least large weekly water changes maybe every second day plus you will have to consider investment in an RO. Discus are usualy kept with unimposing fish such as tetras and rams. I'm not an expert but would say no.
Do lot's of your own reasearch and be very carfull when considering discus fish they, it is a shame they are so beutiful
