Can anyone ID this coral?

[GoldfishJoey]

I have no clue what this is and I don't know how to properly take care of it. Considering its been alive for a month is a good thing. The little hand things come out at night and it expands to this size but once the lights go on it shrinks and it looks like a rock. It's pretty cool looking and I'd like to keep it around and take proper care of it. So if anyone has info on it can you please help? Thanks!!!

They don't like much light,usually put them in cave like area under overhanging piece of rock.They can actually move a little and change their shape to suit their needs.
