Free coral?

[Brian Therien]

So the piece of coral you see came on the live rock I purchased. There is another piece besides the one pictures but it is flat, roughly the same diameter, but not spherical as this one is. Is it a coral? Is it alive? Since my tank is early in the cycling process how should I go bout taking care of it? Keep in mind it is the end of the day, my day time running lights have been off for a good hour and a half so it seems to be closed up. Also the purple on right behind it, I noticed that is closed also. Is that a coral as well?
