Clownfish with Hair Protruding from Face

What is it?? Both of my Clownfish have white hairlike substances protruding from their faces. I will try to post a couple pictures but if someone could tell me what it is and how to treat it I would appreciate it!!! Also do I need to treat all the fish in the tank or just the two effected fish?

It looks like the forum has changed since I was last on here... Does anyone know how to post pictures now?
