Discus get tall. Of course you could keep one in there (20 high better) but two who aren't mated might fight. Get 4-6 juveniles and let them pair off. Then sell the others or set up another tank for them.
Discus are hard to keep and if you don't know that then you'll spend alot of money to have your fish die. Do some research first and I hope you've kept other fish before also. If you have good tapwater I'd recommend 50-75% water changes everyday. All you need is a heater, an air driven sponge filter and alot of water changes. If you got bad tapwater think about getting a reverse osmosis unit but thats a big investment (but at least you can drink the water too).
