ID help again - mystery critter from live rock

[Tippfish]

ID help again... I really appreciate all of the help IDing my live rock creatures. Looks to be sort of worm. Stays attached rock.

They appear to be the arms of a mini brittle starfish....these are good and therefore are "keepers."

 

[saltyphish]

looks like arms to a small brittle starfish to me as well

Thanks for the quick responses. As a first time reefer, I'm a little nervous. Especially, after the positive ID on an aiptasia

I have a lot of them as well. They are a great "free" addition to the cleanup crew. No need to remove them.

And on a side note, aiptasia is not the end of the reefing world. There are much more severe issues you could face. In the grand scheme of things, aiptasia are easy to deal with.
