Please help ID what's growing on my rocks!!!

I have a 'fuzzy/hairy' spreading substance growing on rocks of my mixed reef. Please help ID? If it should be eradicated, how should it be?
Thanks

I don't know what this is, but I'm thinking it isn't good.

I like the mean mugging clown tho

Hard to tell from the pic, but looks like colonial Hydroids.

All images are just out of focus. Can’t see any structures

Looks like some sort of polyp. Maybe blue clove polyps.

I agree, the look like clove polyps but can’t be sure, would need a clearer image
