Update: Acans didn't last 1 week. After about 48hours they started receding, then basically dissolved into nothing.
Light Placement - Location is bottom to mid in the tank (30" deep) so I'm not burning them.
Flow Placement - Location is almost exactly in the middle of the tank to provide moderate flow.
Purchased at local LFS (although I'm not holding the LFS accountable).
I use Radions and haven't lost a single coral or fish since the day the tank wsa setup.
This frag was part of a much larger colony (that I saw before the fragging), I purchased the frag about 4 days after the frag process. I guess it just didn't make it through the frag process.
LFS still has a frag or two left, so I may wait a week or two and see how their frags recover....and try again.
Pretty bummed.
