Weird worm?( not bristle)

[aj2001]

I've got a weird worm living in one of my 15lb pieces of LR, it looks almost like a anemone tenticle,its smooth,at least 8+" long around3/16" thick kinda light grey and black.its mouth looks kinda like a tube worm or an aptasia like flowering brown teeth, but it sucks them inward like something from a scifi movie,only comes out at night and quickly retracts w/ light,cant find info anywhere,but between this and the 12" bristle worm hidding in the same piece my gf is freaked out.
thanx much

It is a peanut worm, I forget right now what the scientific name is, but they are harmless, and nice to have.

Thanx Laura, He is out in the open today and I see where the name peanut comes from. I did a search now that I know what he is, its just strange that mine is out "eating w/ the tank lights on.
thanx again
