White growths on clown

[sweetdickyb]

Hey guys,
I've noticed that one of my clowns has developed white cotton like patches all over him the last few weeks. He's very active and eats like a champ. I've never seen anything like this so I was hopeful someone may know what it is and how to treat it. Water conditions are perfect and everything else in the tank is thriving. Thanks!

My guess would be Lymphocystis - check this article: Lymphocystis Disease in Fish
