Well, never did figure our exactly what is was. No one seems to know for sure, but we suspected some kind of bacteria or fungus.
I was very persistant with this fish. After losing 3 to this disease, went and purchased 2 more from a different lfs
. The same symtoms began to set in and I treated with a combination of Maracyn and Cupramine (in case it was parasitic.).
These 2 fish have recovered fine and are going into the main in a week.
If it looks the same, I would treat pretty quickly. This disease was taking them out pretty fast.
