I had two fish in my qt tank. One peacock bass with fin rot from fighting and one tsn with Ick. The temperature was already 82F and the tank already had salt in it. The fin rot cured and I thought the Ick cured because I didn't see it on the peacock bass, but this morning I went in to check on them and the peacock bass has spots all over his fins and the tsn is acting all crazy zooming around all over the tank, so apparently the high temp and salt didn't work. What can I do now?
