I lost an angelfish in the same tank to ich several weeks ago. Around the same time my clownfish got slimy (looked more film-like than spots), then it cleared up, then it came back last week. I gave him a 3 minute freshwater bath, dont know if it helped or not. The slime is mostly gone, but the fish is not looking good. In the last few days the slime/film went away and then he developed dark spots behind each eye. At first I thought it was just skin healing. He also let my fire shrimp clean him multiple times, which he's never done before. He is hiding more often.
In the last 2 days the dark spots turned into protruding loght colored "growths" and this morning I see more have appeared on his fin and body. White splotches on his outer fins too. Pictures from today attached.
