long thin tenticles coming out of live rock
I've spotted some long (ranging from 2"-3") tenticle type object coming out of a piece of live rock. They look like single strands of white hair. What i'm seeing is a longer piece strung out between two rocks which appears to be pulling in stuff (food?) along side it are two other pieces that are shorter and seem to be feeling around. Does anyone know what it may be (i know it's not bristle worm)? Should i be concerned?

I wouldn't be concerned, I have hundreds. I can't recall the name, but if I recall correctly, they are just scavenger worms. Do you have volcano shaped piles of sand? I usually see them coming out of those, but definitly in the rocks as well.

I have something sorta like that, its a lot smaller they look stiff not reacting to water movement and they have yellow tips, they don't do anything and they go and come, not really worried about it

depending on the appearance (i.e., a photo would be good...  ) it could be a specie of spaghetti work, a vermetid snail (especially if it comes from what apears to be a calcerous tube) or a specie of brittle star, pix would help a lot.

I have a few of those. I did a search for worms and the closest I came to an ID was for a spagetti worm. If you find something different, let me know.

I haven't seen it since so there won't be any pictures.It almost looks like a single strand off of a spider web.But it moves on it's own not with the current.I guess it is harmless,unlike the clicking noise I was hearing last night.I wonder if I have a mantis shrimp  |

Rut-Roh, you have a red lensed flash light? You may wanna spy on your tank for a few evenings to see if you have one of the little boogers.

I have what looks like a Serpulid feather duster, except it doesn't have a crown of feathers. Instead, there are two short antennae. protruding from the tube's opening and it sends out strands of mucus several inches long. What is this?
This is probably a Vermetid gastropod. It is a harmless, sessile snail that captures detritus and plankton with a mucus trap. They form calcareous tubes that project them out into the water column. An excellent article by Dr. Ron Shimek is at http://www.aquarium.net/0897/0897_8.shtml

i have something that looks similar to what you described, but it lives in a shell. it looks like this: picture and empty astrea snail shell. now picture coming out of the opening a thin tube covered in crushed coral, about 1 to 1.5 inches long. then sometimes coming out of the tube is a long thin clear/white 'tentacle' which sways with (and against) the current. I dont know what it is either. it looks too small to be the vermitid gastropod thingy in Shimek's article...
