what is this?

[malkore]

while watching my tank last night, I saw what I thought was some kind of thin, strand like algae, semi-transparent.
however there seemed to be a rhyme and reason to the way it was undulating.
low and behold, these tentacles grabbed a piece of fish waste, and fed it into a hole in my live rock.

I'm assumign this is some kind of very simple invert. any clue as to what it is?

doh, could this be a 'spaghetti worm'? (just saw a post a few down)
but there were a bunch of these tentacle things, not just 1.

Spaghetti worms have many tentacles, not just one Yes it is likely a spaghetti worm.
