I've found that once acclimated to tank life, they are one of the hardiest SPS I have. If it's a new mariculture piece, then I would worry about the sensitivity of the piece as they tolerate very little.
My echinata has been through it all and still chugging along. Heck, it was one of two corals that actually looked better when I had the high salinity and high nitrate debacle.
I believe ARC has mariculture pieces but they've been grown out in their own grow out tanks prior for sale. Think of them as not just brand new to the reef tank world, but more 1st generation as they have been acclimated some already.
