Hi!!!
I have been keeping a few discus for about a month now and they seem very happy and health in my tank. My water in Central Indiana is VERY VERY hard, which I'm sure you know is not ideal for discus.
I keep my temp at 82* F, feed frozen blood worms twice a week and the rest of the time feed them Cyclopreeze Micro Crabs. I also only do water changes once a week. So, in my first hand experience, they don't seem to be very hard to care for at all. But, this is just my experience and I'm sure there are many more here who would disagree.
I acclimated my fish slowly to their new home, which helps significantly. I try my best not to overfeed the tank and keep up on my water testing and water changes. I would say go for it. I would recommend buying all the discus you want at once, however, because they are cichlids and can become territorial if introduced to the tank at separate times. I had a hard time getting eeryone in my tank to get along, but thing are going well now
Don't be intimidated!!!! Just keep an eye on your water conditions and at the fist sign of trouble, water change!!!!! Always keep up on your weekly changes, of course
