Wow. That is blue. Don't cut it before it's time, but put me on a list for a piece whenever. Where are some full tank shots, Phu?
Roy,
Something else you might be able to look into is challices and the like. They won't be as vibrant as Phu's seafan, but can add some red and oranges and bluish colors. Most are okay under PC's, but I'm not sure how well they hold color under PC's. Zoas are the best option, but I've heard that some of the blue zoas love tons of light, too. I can't think of much else blue... Maybe sponge, but they would likely be tricky to keep alive. Check out some LPS for different than normal colors under low to med light.
