Spots on Blonde Naso Tang

[jonespkp]

My Blonde Naso Tang has three spots on it that appeared today after a water change. She usually will develop several white spots across its body when I've had my hand in the tank. Today, however, these spots developed and have not gone away. She is eating algae sheets and has eaten Reef Frenzy today. Any ideas on what this could be?

Pictures are not clear enough. Can you describe appearance? Fish behavior? When was the fish acquired?
