It thrives in your Nano, though... a 12 gallon tank in which evaporation, heat fluctuations and such vary so much more quickly. I knew the species was fussy, and ships poorly - but once it began to spread, I thought the worries were surely over. I have LPS, SPS, a clam, several things that would seem to be more particular to water quality, lighting, flow rate, etc. ad nauseum. Should I stick that rock in another tank (only one not treated is a
FOwLR) and see if it recovers? I loved those little guys grasping at the water while I watched the tank.
