Weird Disease?

[baboon]

I have a Blue Hippo Tang that came down with Ich because another fish I introduced into my tank got it after 2 days in the tank(couldn't QT b/c of unfortunate circumstances). Anyway i got the other fish out and later that same day my Tang came down with Ich(I think due to stress from trying to catch the other fish). Well upon further examination I noticed it was breathing EXTREMELY heavy and not moving, it stayed in the same spot all day today. Well i have pulled it out of my tank to begin treatment. The WEIRD thing is my Bicolor angle has something strange going on with it. It is breathing EXTREMELY heavy, like the tang and I mean heavily, but the thing is, it looks like it's mouth is BLOODY???? It looks like it got in boxing match. What could this possibly be? By the way my tank cheched out fine with pH, Nitrate, Nitrite, and Amonia.
Thanks

Ok, so I woke up this morning to find my Blue Hippo Tang dead less than 24 hours after getting Ich. It had the minorest case of Ich I think I've seen before. I think something else might have caused death, not Ich, because of how heavily it was breathing. It only had about 4 spots of Ich on it's entire body. Does anybody have any clues as to what this could have been. I have never known Ich to be able to kill this fast. The Bicolor Angle is still alive. Any and all suggestions please.
