Grayish spots on Clownfish

[Giantclownfish]

I started noticing that my clowns were acting a bit weird and noticed these kind of grayish spots on them. Any clue what this is and how to treat. Thanks!

Can you describe how the clowns are acting weird?

I can’t make anything out in the pictures, maybe a video would give a better view?

Need pics and even video under white lighting. Hard to see anything on a white fish under blue lighting.
very faintly I believe there is presence of black dots
