I got a male crowntail Saturday night from walmart. He looked like if he stayed there much longer he wouldn't live. His fins were in pretty bad condition though I do not believe he has fin rot seeing as there are no dark edges. They mostly just looked torn. After having him home for a few days his fins started growing and he seemed very active. I've been doing everyday water changes with stress coat, aqua safe, and aquarium salt. Last night I did a water change and now this morning his fins seem clamped and he has stress lines. Hes also not eating and seems a bit discolored. I have no idea what could be wrong. I haven't been able to test the water as I do not have any test strips currently on hand but there shouldn't be anything wrong with it. I let the water sit for 24 hrs before adding it in and I use aqua safe just in case. Is there anything I should try doing other than just keeping up with everyday water changes with aquarium salt and stress coat?
