I have a sick cory cat which I have asked for help in treating previously with not much feedback. it started with what looks like fin rot. I had been treating with triple sulfa and anti fungal meds. The fish did not get any better so i followed that with furan-2 which is supposed to be for tail/fin rot. However, now it seems the dorsal fin is gone and whatever the infection is has moved to the scales below the dorsal fin. The fish looks horrible now. I have had him 5 years and am very distraught. I have hiom in the container ready to euthanise.
is there anything i can try at all or should I just do it?
