What is THIS green thing?!?

[katonge]

Does it have multiple small mouths on little tentacles? In theory it might be picking up grains of sand with them?

It’s hard to tell. The dark area with the yellow parts seems like an outsized head of some kind?

Looks like a bobbit worm. I would remove it.

Not sure if this helps or not.

Sticking with my original diagnosis. Bobbit. Set a trap and get him out.

How do I set a trap?

How do I set a trap?

Soda bottle. Cut off the top third. Invert into the rest of the bottle, ie twist part goes into the remaining 2/3 of the bottle. Put in a piece of shrimp/fish. Place outside the rock before lights out. Worm goes in, can’t get out.

Thanks!

That looks so close to a bobbit that I would get it out, even if I needed to get rid of the rock it’s in.

I don't think it's a bobbit. Bobbits are extremely fast and cautious- poking one would cause it to retreat, fast. It could be some other kind of eunicid worm, which may be totally harmless. but I'd expect most eunicids to retreat a lot faster.

It doesn't look particularly healthy. Seems to be moving oddly. Removing it is probably a good idea in case it's dying, but try not to kill it- it may be something that somebody would want. Put it in a container of some water and get a really nice close-up pic.

In case you were wondering, the little white tendrils in the sand around it look to be from spaghetti worms. Harmless detritivores the majority of the time, though they can annoy corals if they happen to reach their feelers across the corals on a regular basis.

Thanks, I was wondering. I think the weird movement may be caused by the flow.
