Vermetid snails. They put out a web of sorts that I've noticed has bothered some zoas in the past, kept them from opening completely. I broke off the tip and they were fine again. Other than that I don't think they are harmful, I have a bunch in my tank.

As for removal people have had scattered success with a few methods. Aptasia X, cutting them off at the base, emerald crabs, putting a dab of super glue over the opening. I'm sure there are other options I did not mention as well.

Definitely vermatid snails. Mostly harmless unless they start growing in outbreak proportions. You can either break them off with tweezers or put a dab of super glue on the end of it to close off the tube. Whatever you do don't try to break them off with your bare hands.

Oh the slices in my hands from vermatid snails! Just like little razors or cookie cutters...

IME they sort of die away over time... I wouldn't do anything crazy to try to get rid of them, In most cases.
