Oh! Everybody seems to be leaving him alone, as he basically stays under a large rock by himself (what he always has done), other than the occasional visit from his friend, a Perruno Cat. He has been totally healthy for over a year since we got him. It actually looks like a thin film of 'skin' has begun to grow back.
I have added quite a bit of salt, mostly because some of the other fish were sick and are recovering from a bad fungus and bacterial infection as a result of the tank disaster.
The wolf doesn't seem to react at all to anything I do. He just seems like he's just conserving energy and letting himself heal. He doesn't seem to move unless he needs to. Breathing isn't labored, just shallow.
I guess it's time to do some deeper reading on the fish. Maybe move him to his own hospital tank? Although the stress of catching him and moving him might worsen the condition... thoughts???
