What's this creature?

[fengzhu]

I have a lot of those creatures on my sand bed and live rock. They usually grab anything that fall to their tenticles and well, "eat" it, or digest it since they don't have month. Anyone knows what they are?

BTW, it looks quite big in the photo, but they are quite tiny indeed, the tenticles are about 1 inch long and as thin as hair.

Thanks.

Looks like a worm. I am not sure of the name but they are harmless.

Maybe spagetti worms, form a tube form sand and such about 1" long.

Thats what it looks like to me. I wish I was cool and had orange ones though, all mine are white. They come out at night and at feeding time and slap and drag accross the sand and pull little bits back to them. My pistol shrimp digs them up and uses them to build his burrows. Its pretty cool to watch him.

Spaghetti worms! Cool critters

I have a huge purple one that has about 10 inch tentacles. Yours are a cool color too. I think they are terebellid polychaetes. Here is an article about them.

Thanks for the answer. I thought they were kind of small pest anemones because they eat like anemones. I even moved one of my corals because their tenticles touched the coral. Now I feel much more comfortable.

Thanks.

It might be somthing other than a Spaghetti worm, Ive had somthing similar to that little guy in my 180 gallon reef and its actually a "Timarete" aka Ball of yarn worm. Im not saying that you guys are wrong its just that its not an accurate picture cuz its missing the key part, the body........ heres a picture of mine.
