What is this? Coral?

I took this last month in Roatan.  It looks like it might be some Fire Coral?   Not sure if it is some kind of sponge, but I've not seen anything like it in my species books.

Sorry I can't tell you the size of this.  I've forgotten. 

Branching Anemone  Lebrunia danae  pg 41 Reef Creature Identification Book, 3rd Edition, Florida, Bahamas, Caribbean.

We see this some what frequently diving Grand Cayman as well.

Thanks.   Seen a lot of branching anemone but they didn't look like this.  I assume there are multiple anemones clustered together here?
