I agree, take a deep breath....there's a lot of people here who want to help you get things right for all the fish. I don't know yet how big your tank is, nor do I know the size of the fish that you have.....perhaps they are small or perhaps they are full grown. 7 Full grown discus will need a mimimum of a 55G tank Since the discus seem to be suffering illness and stress and the other tankmates are not, I would be inclined to advise you to get another tank up and running for the sick discus ASAP and get those discus in their own tank for treatment. If you've got a 29G, that'll do for treatment purposes. Get a filter going on that tank using some filter media from your existing tank. You need a reliable heater in there too since you need to keep them at 30C while they are ill and during treatment. I'm not sure where your discus got the ich from unless you added a new fish recently and that fish introduced ich into your tank. With the stocking you've been keeping, and only one water change per week, even though it was a large water change, it wouldn't be enough and I would guess that your water quality was still very poor, too poor for the discus so their immune system has been weakened. What are you using to combat the ich?
