So... We have a pretty large aquarium club in my county and we communicate regularly via facebook. Someone just posted a picture of a 60 gallon bowfront aquarium, with what appears to be 6 juvenile (2") discus. Very pretty little fish. Obviously, a raging debate began, as does any debate when Discus are concerned. I threw my hat into the ring, but I'm more interested to hear your perspectives before I get too involved. Let's assume their filtration is perfect and they do 20-30% water changes a week. How long could they keep them in there until, for the good of the fish, he would have to transfer them out. I think the height of the tank is around 20 inches (according to them). He thought of adding two more and that he would NEVER have to transfer them out!
