Discus may not be what people consider a beginner fish but, personally to those people keeping them, when you got your first discus you were a beginner with them too. To be honest discus can be really finicky but, if you do your research I would say that you should be OK. The discus prefers a fairly large tank if you have a lot I would only recommend getting only two max with your tank size, they like soft water, but can be kept in hard water though not preferable, keep pH in between 6.0 and 6.5 but you can go up to 7.0 pH at max, and keep temps at 77° F to 85° F. I keep my discus tank at 80° F. But I agree you should make sure your tank is cycled first, and give it some time to establish itself get some things in the tank so the discus can hide and you will be in good shape.
