ID on this green thing?

Not sure on this one. Hitchhiker. It's only about half the size of a penny and is from the indo-pacific region. Any idea?

Looks like a majano anemone, bad guy.

Found some more examples and majano it is. Thanks for pointing me in the right direction.

I've never seen a speckled majano before. It could be something else, like some relative of corynactis.
