I did put in nori but not right by or under him.. i will do that when I get home.
Good links/posts, but don't want to count him out (e.g. not kill him) until no other option. water quality is OK. new tank with new rock, but I have been monitoring the ammonia and have no signs of it. I used my DT water to start it off and he started shedding 4 days later. will continue to monitor.
poor little dude.... however he went back into the QT tank for destroying all my Zoa's in my tank... slurped them up like popcorn. i should have just put him in my sump instead.
