Copperband & pectoral fin

[elaw62]

added a copperband about 3 wks ago to tank. He's been eating frozen mysis but that is all he'll eat for now. this white are has popped up on his pectoral fin and I don't have a clue. Doesn't look like ich, I was thinking maybe Lymphocystis but really don't know. what are your thoughts?

Looks like lymphocystis to me. Given good water quality, it should go away on its own.

does stress trigger this. yellow tang gets a little fiesty with him sometime.

Lympho is a virus. Stress could be a factor; but I've never seen anything that links the two. I doubt if it is. Keep a good eye on these two; established YTs can be very territorial/aggressive and CBBs don't do well with aggression or even a lot of "hyper" fish. If the YT gets too rough; I'd put the YT in your QT and re-introduce him. This can help with the territorial problem. How big a tank are they in? Both these fish need space.

90 gal. upgrading to a 120-150 in a year or two. YT leaves him alone for the most part but every once in a while makes a run at him. Copperband is larger than YT.
