Help! I have a 24 gallon salt water tank with a maroon clown fish and a purple tang. I went on vacation and I bought an automatic feeder for the trip. I put it on the absolute minimum setting but it dumped way too much food. When I got home the fish were acting weird so I got out as much food out as I could and did a large water change. The fish had some white spots which I though might be ich (not totally sure) so I put some medication in the water just to be safe. That has all cleared up and the tang is behaving normally but the maroon clown can't seem to "float" in the water. He just sits at the top right side up and occasionally sideways. The very top point of his back is starting to get sore and I'm hoping there is something I can do to fix the problem. This is the best fish I've ever had and I don't want to lose him. Any help anyone could give would be very very appreciated.
