ID help please

[jdiver]

On one of my pieces of lr, there are a half dozen critters that I am not sure what they are. They are coming out of holes, and have a "crown" of about 20 thin strands that shine fluorescent green, blue, red and yellow (I'm assuming refracting the light). In the center of each one are 3 or 4 what look like little tentacles moving around. They're really quite striking with the different colors. Sorry I can't post a pic, but does anyone know what they might be from my description? Thanks.

it could be some sort of polyp

live rock often comes with all sorts of good critters

corals, polyps ect..

just keep an eye on it see what it looks like when it is bigger

 

good luck

I think it is some sort of a snail.  I posted a question similar to yours a while back and that was the general consensus I got.

Not sure what it is without a pic, but heres a good article for  ID'ing various hitchiker critters:

Look thru the various pages its makes an interesting read anyway, and adds to your knowledge.

 

Hope its helpful.

Are the tentacles completely smooth, with no visible structure?  Do they lie flat along the substrate, stretched out noticeably?

 

The irridescence makes me think of fine bristles, or perhaps cilia -- and that makes me think of terebellid polychaetes.

Thanks for the replies.

 

Sahin- I have that hitchhiker database bookmarked and unfortunately didn't find it in there.

 

grantlaw- That first picture link you posted looks almost exactly like them, minus the irridescence which is likely difficult to capture in a picture. At any rate, spaghetti worms are what they are. Thanks!
