Hitchhiker ID

[StephaniePlyPet]

Found this critter on the glass of one of our reef tanks and wasn't sure if it was a safe hitchhiker or not. Since bright colors usually mean "stay away from me" we popped it in our refugium to watch it and try to ID it. Almost 3 weeks of being angry and clamped up but it's finally starting to peek out now. Any ideas? Nudi? (it's currently almost half out of the water for reference)

Small sea apple?? Just a guess. Nudi?

Don't think it's a sea apple, thanks though. It's starting to move a lot actually and looks almost like an anemone, moving it's tentacles about.

Strawberry anemone?

It's definitely an anemone of some kind but not looking like a strawberry unfortunately, I'm thinking possibly a Waratah Anemone? Anyone else have any idea?

Beadlet? Just throwing it out there based on google photos.

Looks like a baby Actinia species. They like to sit just below the waterline. In the wild you find them often in the tidal zone.
