My old (at least 18+ years) maroon clown has been fight a large lump on her side for a few weeks now. It will grow then become smaller and then grow again. She has always been a strong fish, so most of the time we let her fight off things herself because she does much worse from the stress of QT. Now we must QT to treat her. Currently it is an open ulcer after it grew so large that she lost her scales in that area. I need opinions on treatment please. Not sure what to do...
