Short update, I got on the Morse Code Maroon this morning and swabbed the area with Hydrogen Peroxide.  I am guessing this fish will likely be dead in the next 24 hours.  Ordinarily, a fish in this condition would be euthanized.  Warning, the picture is pretty darn graphic.  The fish’s entire upper maxillary has been rotted through, leaving two pieces hanging.  I would be truly amazed if this fish were able to turn around,, but without finding an antibiotic regiment that is affective, this fish is going to be another loss.

Sad to see this one going down this path, and really ticked that I found the problem early and addressed it early and it has still progressed unabated.
N0te – the yellow tint in the water is from the Maracyn / Maracyn Two.
