Any ideas on what this might be?

I need some help identifying something that has been growing out of my live rock. The tank is only about 10 days old and below I will try and add 2 different pictures. I will also describe the "thing" now. Sometimes during the day it seems as though it is completely closed and looks like a deep purplish/pinkish color with a white dot in the center. When it is open it is the same color but lighter with "feelers" that are clear/whitish. Also, under our blue led lights it seems to glow an orange color. Below I will have two pictures, one with the blue led lights on and one without. The pictures show a bigger image than the actual size of the "thing". I zoomed in all the way with my iPhone as the "thing" is smaller in diameter than a penny...maybe about half the diameter if not even smaller. Any help or ideas on what this could be would be greatly appreciated.

The "thing" I need help identifying is located just to the left of center in the pictures by the 2 green leaves.

It's a Corynactis. Relative of both the anemone and corals. It won't amount to much of anything.
You also have an Aptasia anemone in the foreground. You will want to kill that one. Google "Aptasia anemone" to learn about them.
