It's all good.
My only real concern with this subject is, as long as people believe these corals will simply start a new life somewhere else, after they bail out, there is no real need to understand what causes it, or how to prevent it. If people understand this is a death sentence, they may work to insure it doesn't happen in their tank.
What I'm about to say is far from anything that could be considered scientific evidence, so please take it for what it's worth.
I've lost track of the number of people, that have contacted me, after their elegance coral bailed out. This seems to be relatively common in this coral, when conditions are right. In every one of these cases, there was something wrong with the system that had the potential to interfere with calcification. Like high phosphates, or low calcium/alkalinity. Some of these corals lived for quite a long time. Six months plus. They often expanded as usual and even fed like normal, at least in the beginning. Unfortunately, and despite the best efforts of the hobbyists, none of these corals started laying down a new skeleton, and they all eventually died.
