Both of the Richards keep this coral.
My experience has been pretty positive. I had a rough patch when my KH dropped, but I think we're getting back to normal now.
In general, here is my experience with the coral. First, it's pretty happy in high light. I keep a few Birds, most near the top of the tank. My orange and red bird are near the top, my orange w green polyps are a few inches down, and my Bird-of-Paradise is much lower (but this is a special "low-light" coral anyway). I keep them under cheap chinese LED fixtures with red and green supplemental lighting (a couple spare RapidLED bulbs)
Second, and I can tell you this from unfortunate experience, Birdsnests DO NOT do well when the Alk isn't stable. Keep your Carbonate Harness around 10 dKH. If this parameter fluctuates much, you may wind up with (please forgive me) Angry Birds.
Soon enough you'll find yourself the owner of DEAD Birds.
Thirdly, the same issues about KH stability also holds true for pH. Even though my pH is somewhat low at 7.8, it's stable which counts for a lot of happy corals. If you can keep your pH stable at 8, so much the better.....we have seen scientific proof lately that reefs under 7.8 conditions may grow, but they don't calcify as heavily....therefore you get more brittle corals. Read that in CORAL mag a couple issues ago, I think.
I hope the other Richard chimes in as well. He has a lot of experience with good coral coloration, which he maintains is due to a trace amount of nitrate and phosphate. I can't comment 100% about that, but I will say this.......his corals are BEAUTIFUL. Hard to argue with success.
