Thanks for the possible ID
I still can't get over how quickly it's coloured up. Most of the SPS down at Premium is usually so browned out it's hard to tell what it's going to look like.
I've got a couple more you can have a stab at here....
The first one I was thinking is some kind of deepwater - the branches are very thin and brittle. I got it the same time as that other one.
This second one hitch hiked in with some live rock I bought for my mantis tank a few months ago. I'm assuming it's Porites.
