what is your acclimation/dip process? tank water parameters? any changes(lighting, flow, salt, fish, invert, etc) to the tank before adding this zoa?

those "high end" zoa's are notorious for melting.

send out an ICP test to see if any contaminants are in your water like high metals which can kill/hurt coral.
