Please help ID, What are these?

These things just popped up a few days ago. They are in one area of one live rock only. The pictures are of the same cluster, just different shots.

75 gallon tank is about six weeks old. Purchased live rock was from an established tank that was neglected for a month or so when ownership of home changed.

There were two on Monday, now there are more.

I thought they were Aiptasia, but the hairy extensions are not very long.

Thanks

Almost look like Zoa's. But i am not really sure, because how white they look.

yup, look like some kind of coral polyp that hung on through rough times :)

Yeah it does, but it doesnt look to healthy!! I hope whatever it is, it'll come back for you. Gotta love those hitch hikers.

Thank you for all the replies. I will keep these for now and see how they develop.
