Could anyone ID this sps?

[Tyler Sullivan]

Hey there. Got this guy at my local frag show awhile ago and with it being in my mixed reef it is the only sps that really glows in the tank. I want to get a bigger colony just like it. Any ID?
Thanks

I'm taking a wild guess with acropora rosaria. I would say it needs to grow a bit to get an ID though.
