He recently developed a cloudy eye, not protruding. He's also rubbing a lot. I have a scaleless catfish in with him. I'm praying I won't lose him, doing water changes now. Hoping that a few of those will help, with addition of pima-fix maybe? I'm really worried, I just set up a 125gal for him and was going to move him into it, but now I'm not sure I should.
