I'm sure its bad, but how bad and what is it?

Grape Caulerpa or bubble algae, picture is very hard to make out. Are the balls connected by a vine or individual?

I think I can see the vine. the grape is a lot easier to remove. Use forceps/tweezers. to pull on the vine part. If you tug on it gently it will get the roots, vine & grapes. It's more difficult to use the fingers. this has worked for me.

I know tangs will eat other types of caulerpa, but I don't believe they'll touch grape. Not positive on inverts either.
