In reefing you sometimes need to act fast! I moved this Miami Orchid SPS coral colony higher on the reef the other day and unfortunately it did not like that move at all!
By the morning it was turning white (dying) from the base up.
I believe it to be RTN (rapid tissue necrosis). As soon as I noticed it I chopped the colony in half 
and mounted it a bit lower on the reef. That quick decision helped to save the top half of the coral (green circle). Phew! Happy reefing ya’ll.
