Zoa of some type?

[Jestor]

Wife just noticed this little fella tonight.

Shell that it is on is only an inch or so long, 3/4 of an inch across.

I ask her it is was from our little Zoa, she said she didn't think so. Zoa is across tank.

It’s a “ball anemone” (not a true anemone, it’s related to mushroom corals). They’re generally considered harmless/neutral, but they sometimes multiply pretty quickly.

I posted and then we started looking ourselves. Same conclusion the wife and I came to.

Hoped multiple answers would lead to the same conclusion.

Thanks for helping.
