Any ideas what this or these are?

Saw about 5 of these swaying around in the current earlier and kept an eye on them and noticed they appear to be a creature? Seems like they are moving a bit. My cleaner shrimp kind of honed in on them but hasn’t like eaten them

Those are either medusa worms or spaghetti worms.
Medusa is a filter feeder, spaghetti worms fish for food with their tentacles.

Maybe spionid worm?

 

[Goaway]

Could be. They might be all close together.

I found one last night that is bothering my Rasta zoas...with the flow completely off....it’s antenna were still moving as if flow was present. Iodine dips don’t kill em. I tried.

Likely spaghetti worms

 

[d0gFartz]

Are they anything to worry about?

 

[SaltyT]

Do they retract back into the rocks when you shine a light on them or disturb them? Your pic makes them look really long, but they look like the legs of striped micro brittle starfish.

All the worms listed are of no worry. What you have is a safe hitch hiker.

 

[KrisReef]

Spaghetti or brittle stars are no problem.

Likely spaghetti worms

Nailed it dude

The tentacle coloration points more toward spionid worms. They can live in rocks.

 

[Goaway]

he could have a whole group of them in an area. Either way, not harmful at all.

You could be right no doubt. I’m just guessing but to me it looked like one or two creatures fully extended. They look so similar and appear to be coming from one main area

I thought spinoid at first but under lighting, spaghetti have that barbed look also . Seldom do spinoid congregate but possible

I was thinking this also just not a buck the system kinda guy especially when it’s a seasoned Vetteguy giving info.

I was also counting the set of tentacles. The id of the worm is difficult because we can't see him.
But again, OP has nothing to worry about.

If there are other tentacles on the other side of the rock of the start point, I would agree with spaghetti. 4 tentacles is not enough to make for a speg worm. Plus the location of them on the rock. You can follow the path the 4 take.

 

[d0gFartz]

Yeh there all in one area only

I'm pretty sure they are legs from a brittle star or serpent star, not a worm at all.
