Hi guys, I'm new to the coral game, and gave a torch I'm absolutely in love with, but he seems extremely moody. The two pictures here were taken about an hour apart, but it could've been 5 minutes. After about a half hour, he'll be back to full size waving in the breeze. Is that a normal behavior? Or should I be worried? All the other corals are ok, and parameters look pretty good except NO3 which is a little under 12 (nyos kit)
