I have not been a member long but have read many threads. What stands out for me is there is no perfect fool proof way to raise these fish. There's a whole lot of factors that can give you success and many that can cause you to fail. You can have issues simply by where you purchase your fish, to what your water is like and how much water you change. I have seen many say that these fish are not sensitive or they're not difficult to care for. I would say that those are incorrect statements. You have to be very dedicated to insure their health. The average fish keeper would fail because they're use to fish that can be neglected. I do appreciate that many here are willing to give advise and assist in any way they can to new discus owners.
