Hi Arreola, Just subscribing to your thread. Beautiful child - mine's 6 now and I sometimes miss the baby days...
Tank looks great back in February. How about an updated FTS (I'm sure you have plenty of time for that, right)? Very sorry to hear about the Ich outbreak though. Are you leaving the tank free of fish for awhile? I've heard something like 4-8 weeks for all the Ich to die off in the water without a fish host. Otherwise, you may add fish and they could just get Ich again... It would be best to put the Diamond Watchman in a QT (and treat for Ich) while the tank sits without fish. If Ich killed off your fish, then that fish probably has it too (this is all just from what others have told me).
Good luck with the Bryopsis as well. My emerald crab has generally been well-behaved, although I did see him tear a couple bites off a new mushroom that was added to the tank once. I also think he ate a couple tiny clove polyps that were hitchhikers on another coral. Hasn't hurt any other livestock though (fish, snails, shrimp, etc.) - even though the shrimp get aggressive with him (when I've fed it pieces of nori). Take care,
--Kyle
