I recently got into reef tanks, I just got this clownfish 4 days ago, in the past couple days he has started to act different not swimming as usual and started just wanting to sit at the bottom of the tank. I removed him and put him into another tank I have in a breeder as I’m not sure what he has that’s at his eye and his tail I included a video and picture, I’d also like to know what medication I can do for him. The other fish that were in the tank with him dont seem to have anything on their bodies nor are they acting different and have been in the tank longer than this guy and he was just recently purchased
