ID Black dots on yellow tang?

[danny zubot]

Just noticed today that my yellow tang has developed black dots on it. They are very small, the size of ick. Is this a different type of ick? SO far the fish is fine, still eating and not scratching. Does anyone know what this is? I find it curious that this is the first sign of an illness in my tank in years, and that it has only occured since I lost my cleaner shrimp last week.
