What type of coral is this?

i have no coral exp but that thing is sweet, good luck with it.

 

I had a red sea fan once and it hated light. The polyps would only open at night. Those blue berry gorgonians require very little light if any at all. I like feeding them with cyclopeeze. I feed 3 times a week sometimes four.
I like using the cyclopeeze particularly because the fish would also eat and excess food wouldn't remain the water because the fish also love it.
Good luck. You don't want too much light on it and give it a low-medium non-direct flow to prevent algae or canyo building up on it.

 

good luck. hopefully you can keep it
