is this an anemone?

[El Camaron]

I just found this a few days ago just bellow my GBTA and well it could be a baby or something else, i have never seen this before. It is about 1/8 of an inch big and only saw it at first when the moonlights were on, the green ring on it glows. Is it good or bad?
Thanks for ahy insight as to what it is.

I had one in my 120 yrs ago.. Greenbeane said it was harmless.
Some other pics

I don't want to get in trouble for posting someone elses pic, I believe the second pic was originally posted by greenbeane. They are a type of anemone but harmless.

Thanks Robin, the first pic you posted is exactly what it is.

I can't swear to the first one, but the bottom pic is of a orange ball coralimorph
