A while back I was at my LFS and they had a discus that had good shape but I could tell it was getting sick so I bought it in hopes that I good get it healthy and give it a better life. I know not a good idea usually. I put it in a 20 gallon tank. I ran salt for the first few days and then treated with Metro for a week and Prazi on two different weeks. After the Metro treatment it started to eat and started to look better. This was back in April and now the fish is doing great. My problem is that it is still in the 20 gallon by itself and I don't want to risk putting it with my 2 stendker tanks. Should I just let it live in the 20 gallon for the rest of its life or take it back to LFS and hope someone buys it before it gets sick again?
