Hi everyone. I have a 6 year old Koran angel. A couple of weeks ago he got a swollen red eye. I assumed he had gotten stung by an anemone or he had gotten hurt on a rock. A couple of days ago he started developing red spots on his side. He has two spots right now and I really don't know what it is. The swelling in his eye went down but it is still red. Does anyone know what it could be ? He is pretty big so if I need to treat him I would want to do it in the main tank if possible. Any help would be really useful right now. Thank you
