so this colony just "appeared" one day, They must've snuck into my tank on my live rock, and it started as just one head that I noticed about 2 months in to my saltwater expedition, now as you can see it has grown to ~10 heads. I was wondering if someone could help me ID them so I can determine how to take best care of them.

this is the best I can do without dragging out the tripod. I shot it in raw, and didn't post process, the center looks a little orange to my eye, but in the picture it looks more tank/bland.
I linked it because it is a larger file.
