THanks you all but yes, I've seen many molts from him and I'm sure this is not a molt. In fact he just molted two days ago. Still I'm bummed. I haven't had a chance to do chemistries yet today but I'm not so concerned because all the fish and corals look great. The crabs are moving around fine, my pulsing xenia and green hammer are open and full. Just wondering if it was his time anyway. I didn't buy him as a baby. At that time I didn't even know what to look for. Now I'd like to get small ones. Ah well. Thanks anyway.
