Orange Cauliflower Coral

[Scavenger]

I bought a couple of small rocks for my tank about 2 weeks ago.When I placed them into the reef, a small orange blob fell out of one of the rocks.
I thought it was interesting so I wedged it into a highly visible area. About a week ago, it started to extend. Since then it seems to be at full extention and is about the size of my thumbnail. Searching the internet, I found a picture of a larger specimen and it was labeled as an Orange Cauliflower coral.

My question is, does anyone have exerience with these corals and know what their proper care entails. I find this a very pretty little coral and wish to keep him healthy in my tank.
