Are you all positive this thing isnt coming back? It is still breathing same pace. I put some melafix in there and as soon as pet stores open I could go get a little set up for it. The other fish that have died (one was really about to explode, insanely bloated, the other got all bent up like turned 90 overnight) they seemed to clearly be on the way out, especially their breathing. This one just seems all there but likely plotting on whoever bit him. Like its breathing hasnt changed, its eyes are active. I mean....is it still the right thing to do if really it had other plans? I just end it, and the whole time its wondering why I am doing that.
