ID! Weird & Fun

So this little guy came free to me on this rock. "Little" being that it was literally a small 2 mm bubble and now it has spread to about 4 to 5. It is not flashy ,it's got these invisible little tentacle things come out when it's feeding – round like a Zoa -
This is the best picture I could get because it is so tiny and partially translucent. Anybody know what it is?

I just realized for a size reference, the granular thing to the left of it is the glued on,frag base on a tiny Birdsnest coral.

It's a ball anemone. Not bad but I have a million of them lol
