OK, I'm sorry but i cant get a picture. Every time i even look over at the tank it moves back into its hole. I will try and describe it the best i can. :)

It looks like a tube style worm.
It has a mane. ( like a lions mane around what i am assuming is the head.)
and it has a long green siphon sticking out of the mane.

Any ideas? Or any directions for a site?

Thanks in advance

A picture would obviously help, but I'm afraid your description doesn't help me much (because I'm not a worm expert!). Unless someone else chimes in, I would say your best bet is trying to run it by Dr Shimek and Leslie on MD.

Probably a snail from the genus Vermetus. We are used to the common Vermetid snails, toothpick diameter, red, calcerous shells and mucous trailing feedng habits. However, there are a lot of differing snails from that genus. Some reach great lenghts in tube structure. Others utilize live rock and/or sand and you rarely see the "tube". They look like feather dusters who lost their feathers but still have two "Feelers" that come out to feed.

If we had a picture (I know how hard that can be) I'd love to go off and research. Otherwise, you may want to look to Dr. Ron's literature regarding Vermetae

Or "Google" some images yourself and have fun along the way :)

it COULD be a peanut worm that's ensconced in the rock. they extend and scour the surrounding area for detritus and other tasty treats.

IME, the larger Vermetids send out a "net" of mucous to capture food and reel it in to feed.
