Hi, ok I've got an idea why mari and wild colonies sometimes don't adjust well to most tanks. My theory is that for however many months or years they've been growing their daylight hours have been roughly a full 12 different from NY. They spend a day or 2 in shipping then go into a store or our tank which we keep lights on when we're up. Maybe the corals have a hard time making the adjustment similar to the way people that work nights never really get used to it.
Just a theory.
