Ive been keeping discus for years and have kept all kinds of discus and all i can say is give it a try and dont worry too much about superior water quality like some will claim, but proper aeration is a must. I've never lost discus even while vacationing for months at a time but lost quite a few when the airhose fell in the water. and just keep them with community fish eg. tetras and rams. Also you should feed the juveniles more frequently or they will get stunted. This happened to me as i first started to keep discus and worried about bloat, their eyes kept growing as their bodies grew slow untill they looked deformed. I dunno i might be wrong but i've grown discus almost to the size of dinner plates
