So my boy Domino still has a nasty fungus infection. It's been over 2 months that I've been trying treatments and I've literally used every medication available (fungal and bacterial), as well as every natural remedy I can find. I'm starting to get desperate.
I went to a LFS nearby that I trust. The man there always gives me great advice and I figure I have nothing to lose. I asked him what I can do to treat this thing. He told me that what he does in extreme cases is to take the fish out, crush up a Nitrofurazone tablet and apply it directly to the spots as a paste. Give the paste 10 seconds to set then put the fish back in the tank. Do this daily for 3-4 days.
I know the betta can survive outside the tank for a little but I want to know the best way to try this and cause the smallest amount of damage to the fish, preferrably none. I know I can't just grab him out and do this, I'd be better to just euthanize him.
What else can I do?
The boy is still very active (and extremely aggressive) so I know he isn't ready to be euthanized and I want to do everything in my power to make him better. I'm not ready to give up on him yet as I'm sure he isn't ready to give up. I just want to give him the best possible chance to survive the treatment.
