I've had lymphocystis on a few fish, usually new arrivals. Always went away on its own. As stated, it is a virus (if it is that) and as long as the fish is eating I'm sure it will clear on its own.

Thank you all for the good advice. It seems the wait and see approach comes out victorious. After one day of increased immune boosting (at least I think it was) feeding he looks o be doing much better. The whiteness is decreased and there seems to be less inflammation. Canreef saves another fish!!
