So what kind of worm is this?

[this is me]

Spaghetti? Looks pretty hungry.
A lot of fascinating things when you look closely at your reef at night. You see the peanut worm at the top? looking for some action.

Jeez, excellent pics of two common types of harmless worms there.
That'll come in handy in the future.

You know what'd be awesome: try and get a shot of all the stuff on live rock that newbies usually will ask, "What is this?"
