Can anyone tell me what this is?

Here is a drawing of a creature that has been growing in my tank for the last 6 months. I have yet to identify it anywhere or by anybody. The center part of the disc(body) is luminous green like an open green brain's color, it's about the size of a penny. When it's arm are extended it's about the size of a silver dollar. It has a pinkish hue to the rest of it's body and when it is closed. On the ends of it's arm's there are little balls or bulbs. It has a mouth in the middle that I have seen it "spitting" out a little ball of something. It seems to be perfectly circular and likes to open itself up evenly. It opens wide when the lights are out and about 5 hours before they go off. I looks really heathy and beautiful. I have attached a crude drawing because my macro can't seem to get a good shot. If you know what this is you are the invertebrate king or queeen. Thanks!

Looks like a mushroom or an anemone. Count the tentacles, if it has 8 or multiples of 8 then it is a soft coral or anemone. If it has 6 or multiples of 6 then it is a hard coral. If it is green then it has zooxanthellae.
