Not really sure what is going on with this Angel. I added the fish to the tank several weeks ago, first week it was looking fine, we went on vacation and came back with it having this bad section on the side. I was thinking flukes, no one else in the tank has anything else visible. During a tank re-arrange I pulled the fish out and did a fresh water dip. Fish was in a bucket with heater and RO water for about 7 minutes before it was looking major stressed. Pretty much everything was off the fish, no spots or anything. Put it back in the tank and added API General cure. Fish looked good for a few days but the issue is back. I re-dosed general cure after doing a 35 gallon water change. Yesterday I added Prazi powder to the tank. Not sure what it could be? Best picture I could get is attached.
