Oh I had something like that too. In the end I never found out what it is, but I do know that it didn't harm anything. XD

very tough to say, but I had a large population of harlequin brittlestars that were breeding in a single rock. LOTS of long black and white striped arms sticking out.

That would be my guess.

so with smooth legs, I'd call it a serpent star versus a brittle star. Not sure if that's technically accurate, but I think most LFS would use that logic.

Harlequins are serpents, so no tube feet (i.e., "no hair in tentacles").

Brittles and serpents usually do not come out from the rocks, so what you're seeing is normal behavior for them. They snag food by extending their legs, limiting the risk to limbs that can regrow if lost.

Thank you for that information. Yeah she extend her legs about 1 1/2 inches to grab food... It's a cool to watch . :fun2:

when in doubt,,yank it out...unless you get an exact iD on it..
I could not disagree more with this philosophy. Even if you don't care about the lives of creatures in your tank, removing things without any evidence that they're harming anything is unwarranted and could deprive your tank of beneficial diversity.
