Looking for an ID

[Black Phantom]

After five years it still amazes me when something new crawls out of the rock. Today was one of those days.
Anyone know what this critter is. Looks like some sort of anemone.

Looks like a sand anemone

Do you have any Pom Pom (boxer) crabs ? I have some and when they molt they lay their anemone down and sometimes don't pick them back up right away or seem to misplace them.

It does look like an anemone,can you get a picture from the other side? With those kinky tenticles it might be aiptasia.

I"ve got plenty of Aiptasia so I know thats not it. This guy is mobile so not sure what to think. I watched him crawl across the glass for a while.
Kind of cool critter:smile:
