Yeah so I put in some cod fish yesterday. Of course it went untouched as he’s still just sitting upright or flailing around sadly. Usually when fish look this bad they pass within a day. He’s still holding on, not eating so doubt that’s gonna do him any favors. I feel like I’m just watching him die slowly. If not from whatever is causing this I assume starvation. He hasn’t eaten in at least a week at this point. Probably longer.Not sure much else can be done. I’d try some maracyn2. If not better then consider euthanizing. Had a lot of rope fish do this and not recover.
