I looked into the tank this morning and this is what I saw. He has stopped spawning, but looks like he is dead or dying, my nitrates were still a bit elevated, and my urchin was loosing spines, but the other corals look good and the rest of my levels were fine, please advise what to do. Also, I touched his shell and he did not retract or anything. Should I remove him from the tank in case he dies?
