the area affected is a top the crest of the damsel's head. It almost looks like a crown slightly raised if looking at the fish from the side. It is almost translucent. So I was thinking ick or Brooklynellosis

going to get a QT tank this weekend to toss my 4 fish in and give my main tank 4 weeks forany parasites to go away as I have seen suggested, but if its brooklynellosis should i just QT the one fish and hope for the best in my main tank with all of the others waiting to show symptoms??
I wish I had pictures to include to better describe what I was seeing.
