Are you talking about the kind that flips over corals?peanut worm ?
no, usually harmless cuc.Are you talking about the kind that flips over corals?
I think they live in sand tubes under the rockwork. I found this one when I turned a rock over.
When I look at images of peanut worms they always have a stumpy end with "hairs" on them and don't look as segmented as this one does. Maybe it is though.peanut worm ?

Your worm appears to be a Bamboo/Maldanid Worm (taxonomic family Maldanidae) - it's harmless/beneficial and a pretty rare hitchhiker. Neat find! As you observed, they build tubes to live in, and they feed on stuff like detritus.When I look at images of peanut worms they always have a stumpy end with "hairs" on them and don't look as segmented as this one does.

Thanks so much! Apparently they get up to 4" long, so not too big.Your worm appears to be a Bamboo/Maldanid Worm (taxonomic family Maldanidae) - it's harmless/beneficial and a pretty rare hitchhiker. Neat find! As you observed, they build tubes to live in, and they feed on stuff like detritus.
With regards to peanut worms, though, that stumpy end with "hairs" (they're tentacles in this case) is actually the everted proboscis of the worm (basically the mouth of the worm when it's open) - it isn't always visibly "hairy" like in the pic you shared, because it isn't always everted; when the worm's mouth is "closed," the proboscis is basically tucked away inside the worm, and not visible.
