Wow there are two of them growing together, the littler one branches off to the back. Do you still think plate coral??? I was thinking something of a branching type, I'll turn him and get more pics tomorrow, but I think plate may be a viable option if they grow off in small groups. Weird I had the same suggestion on another board.
Keep the ideas comeing if there are any others, at this point I am still open to options even though we have two very good and possible ID's here.
