Hey all, I recently bought a Flame Angel for my 36 gal tank. I didn't notice until I got him home that he had a few white spots on his tail fin. Since introducing him to the tank 3 weeks ago, he has acted very happy and healthy, nipping at rocks and eating like crazy. Each day I monitor his spots, as sometimes they are gone (cleaner shrimp loves him), and sometimes they are extra prevalent. None of the other fish in the tank have any spots. Any ideas what might be going on here?
