ID please?

[Shooter7]

I know the picture is not real good. The color is mainly a purplish color with bright green polyps. I need an ID and, if possible, some insight into what keeps it happy. I have had it in the tank a couple months now and it's not really moving forward in growth like my other SPS are. I'm just wondering if it is a coral that would enjoy more light or less light than it's getting. Right now, in a 24" tall tank, it's slightly below the mid-level of the tank. I can move it up or down as much as 6 inches. thanks

id say move it up and into an are of high flow, also, i would mount it horizontally to get more light to it.

Funny you should suggest that, not only did I move it up to more light and flow, but it's actually at about a 45 degree angle now, so not quite horizontal but it is certainly more so than it was before. thanks
