GeorgeD Posted September 24, 2020 Share Posted September 24, 2020 Need help! Everything was great in my discus tank until this morning. Most of the discus are clamping their dorsal fin, colour is dark and they are slightly tipped on an angle. A couple are hiding inside a flower pot thats in the tank. Water parameters are good. I did my standard 50% water change yesterday morning, same as I always do. WC done twice a week, same as I’ve always done. i have a sponge filter going, along with an air stone. I have a canister filter on the tank as well, and when I saw the fish this morning, I added a hang on filter as well. I think I added to much Prime yesterday, could that be the problem? Any suggestions? Thanks, George Link to comment Share on other sites More sharing options...
