Worm (?) on Coral

[Carl Rosleck]

I noticed yesterday as growth on one of my coral frags. Can anyone ID this for me and let me know if it's cool or something to worry about?

Thank you in advance for your input.

Looks more like algae to me but hard to tell

Looks like it might be cyano which is a bacteria. Can you blast it off?
