I've had this Monti in my tank for just over a year, and it has what I would consider good growth. It was approximately 1" x 2" when I got it, and it is about 8"x6" and has two tiers now. It was orange when I got it, with a distinct white ring around the perimeter (growth). I've been experimenting with raising my nitrate levels a bit to see how my corals respond, and over the course of the last week or two I've seen a dramatic color change with my monipora.
With my lighting, it appears to be turning a purple color, but wanted to get some second opinions. It does appear to have lost the white ring around the perimeter, but I don't believe that was a recent change. I have no reason to believe that it is doing poorly other than the color change. I've been working to get my water parameters into the ideal range, and have seen a pretty big response in my LPS. I played with the white balance settings quickly, so hopefully it shows enough.
