What a beautiful 7-month tank! Don't blow it now... LOL.
I had a large, beautiful Elegance coral for about 7 months, and while still looking great, it just up-and-bailed from it's skeleton. It floated around the tank a few months (still looking great-- go figure), but eventually broke apart and wasted away. However I think you have the skills, from what I can see. Go for it!
