Clownfish Flashing

[StartingATank]

So, today I noticed my clownfish flashing on a rock in the front, it looks like they are trying to itch something. It is mainly my male Clownfish, but the female does it here and there, and It is always in the same area, but it is not anywhere close to where they are hosting. Physically fine, swimming normally, eating normally, no signs on skin of anything. Tryed to get a video but they are camera shy. Nutrients normal. Dosing nothing. Other fish fine and no show of aggression. Please help me with this. I think I forgot some info. Sorry if I did.

I try, but once I get the camera close, my clownfish swim to the back of the tank.
