Default What is this?? *PICS*

First...I have tried taking pictures of it but the tentacles are so thin that they dont show up.
SOOOO a description of what I can see is the best I can do. I have seen 6-8 tenticles that seem to be able to reach about 14" in length, they are about as wide as a thread and feel all over with the tip. they are brownish in colour, and come out during the day. I have some spaghetti worms in another tank and they are not nearly as big as this thing I am describing. I assume it came in on the live rock, it hides behind/inside one of the rocks. I used a grabbing device to try and pull it out and it broke off the tenticle I was touching and pulled in. I have tried to no avail to see its body with a light. Doesn't seem to affect any coral that it touches and no livestock has dissapeared...yet.
Sorry but this is all I have at the moment.
IF I can get any type of pic that shows it I will post it up right away.

probably a brittle star. Are the tentacles sort of greyish and possibly striped/mottled with black? Likely they're tiny brittle stars.

here is pic, remember this pic shows it as pretty big when in actual fact the disc is about the size of a pinhead (maybe a bit bigger) and the arms are about the diameter of a pin. They're pretty tiny critters.

And they're good

No I have a few of them in my tank and I would know if it was one of them. The arms?/tenticles?/legs? are brown and look smooth.
the brittle stars that I have are close to what your pic shows and imagine the legs as thin as a star but as long as your forarm. and they dont seem to taper at all.

I know without a picture it will be tough to figure out but they are so thin they dont show up on the sand. it seems to only "feel" the sand

I have the exact same things in my tank but I cant help you on identifying them. Mine just seem to come out of nowhere (the face of a live rock) I thought it was a thread so I pulled it off(came off after a bit of tugging) but 4 days later it was back.

I still say spaghetti worms, there are different types and the tentacles can reach 4ft long. There are some pics half way down this page
