Some type of worm?

[beyondcomp251]

So I saw this guy peakin out of some liverock. When you touch it it shoots back in the rock, greyish worm looking. Any ideas? Its the grey worm in center photo

I cant really tell where the worm is. It would help if you circled it

can you try and get a better picture?

Hard to tell from the picture. Perhaps a peanut worm?

i wish i could that was def the best i could get it pretty down in the cave of liverock. It def has a warm like look and texture to it. It pokes around from that one crevice and if I touch him he'll retract back for a few seconds.

 

After looking at a few pics im going to have to agree that its a peanut worm. Just surprising as my tank has been established for years and never saw him. Guess thats the beauty of reef tanks..always surprises

Could very well be a peanut worm. They usually have a striped white and black body, and they have a mouth that has little white protrusions like tentacles, but very short.

 

You can tell if it is a peanut worm by seeing if it unrolls itself kind of like turning the fingers of a glove inside out. They only come out about 2 hours in the day as best I can tell, so it doesn't surprise me that you haven't seen it before, especially if you only have one. Took me a month and a half to find my first, and I have like half a dozen.
