Worm with a fuzzy “arm”

[T-J]

This guy is under a zoa frag. It’s not a vermetid snail. It sends out a single, long arm and then retracts it. The arm looks like a moth antennae. Best pics I could get.

Bumping since I posted this pretty late last night.

Very hard to see. Only one of the pics looks similar to a bristle worm.

Spaghetti worm ?

Annelids: Terrebellid, Spaghetti Worm | Shape of Life

The spaghetti worm gets its name from its long feeding tentacles.

or maybe a small bobbit worm

Not a spaghetti worm...well, not one I've ever seen. This is a singular arm that goes out. Only comes out at night. Attached to the underside of a zoa frag plug.
Definitely not a Bobbit.

only way to find out is to remove that rock try and get some better photos ? looks interesting.

touch it at night see if it reacts to it? does it retreat?

is in coming out of a rock ?

is it on the frag ?
