My yellow tang has been missing the top part of his fin for a few weeks. It also looks orange along the area where it ripped off or what ever happened. I also just noticed a small nip of the bottom of his bottom fin also. He has had a minor case of HLLE
which he has been recovering from since I removed the carbon, so I thought he wasn't healing because of the HLLE
, but I need help trying to figure out if it is fin rot.
