Thanks! I have fed it very little the last year, but started feeding a bit more lately. I've tried to keep the feedings down so it doesn't take up the tank too fast, but sure likes to be fed, and I see a big difference in it's posture when it's fed well. Soon, quite a few corals will need to be moved for it. I know these guys turn into huge monsters.
Interesting about the glowing red tips. In real life, the tips seem to have a more yellow or orange/brown color to them under tank led's. In pictures, they look green. With a flashlight, they also look green. The first, fourth, and last pic look closest to color in real life. The second and third pic were taken flash only in the dark at night, a few hours after lights out.
