They are all on a little stalk and they close up in the dark. I have several clusters of them all around the tanks 300 lbs of LR.

Those look a lot like the button polyps I got as hitchikers. Your's are a nicer color though :)

How big do they get?

[toddpolish]

yeah, nice color!

Don't think they get much bigger, but they reproduce.

Button Polyps, really nice color for free. Typical to open in daylight and close at night. At some point, they will probably spread so much you will have to weed them out. Good luck!!
