I just bought a Flame Angel last Friday and he went into the QT. Looked and acted fine through the weeekend. Then on Monday, he looked like this (sorry for the bad quality pic): He had 3 ICH like spots above his gill as you can kind of see. On Tuesday, two of the spots were completely gone, with just the top one still there, but less visible (not protruding as much). Yesterday, the top one was still there, and you can see how far it was protruding here: There was also one very small spot on the other side, closer to his tail. Another weird thing was later last night, the spot was again protruding less and could barely notice it. I have not done anything yet. I have a 10 gal BB HT I could move him to if needed for a hyposalinity treatment (I read angels don't do as well with copper treatments). He does not seem any different than when I got him. Breaths the same, does not "scratch" anywhere, eats the same, etc. Thoughts?
