Need help identifying!!

I’m not sure what this is? Is it cyano? The rock has always had these red areas but they were never extended out like it’s growing? Tank is 2 years old.

Scrub off easily with tooth brush?

If it brushes off easily, it's probably cyano.

Looking at the pic, though, with those little branches, I'd wager it could be a gracilaria species.
