As those of you who follow my journal may know, I was gifted a lovely pure red HM male. He was quite small when he was gifted to me. I QTed him for over 2 weeks. No symptoms. Perfectly healthy...
I moved my Herman into a 10 gal heated and divided planted tank with my friend's large DbT male. I'm not sure how old either fish is. Herman (HM) is roughly 7 months old. Link (DbT) is an unknown age but is quite large.
After being in the tank together for a couple of weeks, I noticed something was wrong with Herman. Upon closer inspection, I believed he has columnaris as he seems to have white fuzz in/around his mouth.
Herman is now in a 1gal hospital tank with the water being changed daily. I have done everything recommended for him and he does not seem to be getting better. It is actually worse.
His entire mouth seems to be held open as though he is holding something white and fuzzy. He still takes breath and still eats though not as vigorously. His color is good but he is very lethargic/sluggish. I'm really not sure what to do for him anymore as I have never dealt with this disease in the past. I have treated fin rot and mystery diseases but never this.
If it clogs his mouth any farther, I'm worried that he will drown/suffocate. Perhaps even starve. Is there some way for me to safely remove any of the "fuzz" to ease his life a little or would doing so only hurt him?
I'm open to suggestions.
