Okay, he actually seems better externally, but still not back to normal. So could we remove that other thread then?I just read the thread and am guessing that the reason that there are no more replies is because OFL pretty much covered all that you could do for the sick fish. You're doing the best thing by keeping him isolated, warm, and in very clean water.
Sorry to say that the fish really doesn't look good at all. I wouldn't throw any meds, at him unless you really think that you know what the illness is. Sometimes they just come up with things that we can't identify and we lose them in spite of doing everything possible to keep them in great conditions.
