I have this growing on one of my rocks, I'm just curious if any1 knows what it is

NO, you want to kill or remove it before it spread through your tank.
Look like Aptasia to me.
Yep looks like a Aptasia (glass anemone)
There's a bunch of ways to get it out.
From a liquid you inject to a wand that somebody here, a vendor sells.... What's worked for me were my peppermint shrimps... But if they big like the one in that photo then the shrimps won't help...g/l
I'm Nemo's mother!
