what kind of worm is this

[Lionfish Lair]

They're correct, it's a species of aiptasia.

yea, that's not a worm, it's either an aiptasia anemone or a curlique anemone, both if which will sting other corals. I have seen them completely shrink back into a hole in a rock, and is common in aiptasia anemone's especially when touched. But I have also seen them do it in accordance with the light. Either way I would get rid of it before it spreads.
