Need help with clownfish

[theyurtal]

So literally overnight my clownfish has started floating around the tank. He has white blotches all over his body. It's not ich. I added a six line wrasse two days ago and they were both doing fine. The clownfish is almost dead but the six line is fine. Does anybody know what is happening to the clownfish?

He died yesterday. I contacted my LFS store and explained the situation. It looks like the six line killed him. I already flushed him so no pics possible.
