He doesn't seem to be having trouble breathing. He is moving around as he usually does. His gills are fine its just the two holes he has between his eyes and mouth. One is swollen. He is not a very strong fish at all because he was not taken care of when he was a baby. Any change to the water at all in the slightest bit and he gets fin rot and has trouble breathing so I am sure they put everything in as I instructed.
