Small, Fast Swimmer in Tank

Hi All,

I got some more live rock for my tank last night and I saw a new creature of some sort last night. I cut out all my lights and was looking in the tank with a flashlight when I saw a small (maybe 1/2") narrow whitish looking creature dart away into the darkness of the rock. This thing was ultra quick. I was wondering what it could be?

Also I have these long white tube things on top of my sand....what are they?

Thanks,

The creature, can you be more descriptive? Or maybe check out Melev's Reef - Visual Identification and see if you find anything close.

Do the tube things look stringy? If they're stringy, they're probably spaghetti worms, which are reef safe. I'm not quite sure what you mean by tube things, can you take a pic?
 
Im guessing the tubes are spaghetti worms to.
As for the other critter,Probably a mysis shrimp that hitch hiked in.
 
it could also be a peanut worm. all you will see of them is a long white worm looking thing. when lights hit them they will quickly retract back into the rest of their body that's hidden inside the rock.
