We picked up a 20 g tank at the LFS. One rock full of Anthelia waving hand coral I placed back in the tank, and the other in my 55 g at home. The first time adding a pulsing Xenia in my at home tank the coral died after the first couple days, and this Anthelia looked the same after a night in my tank. I then took it back out and transferred it to the 20g. This is what it looked like today (day 2). Some of the polyps came out only a little bit, but were closed all but one arm that looked as if it was almost cut completely off. One pick is the thriving and the other is the dud. What do you think?
