I bought this piece from the lfs Saturday because it looked great and healthy. Pic in store attached. Acclimated and dipped it and placed in a spot with low light and low flow. It has yet to open and appears to be dying because the polyps around the outer lower edge are gone and the skeletal structure is breaking down, saw tooth like on the edges of each pocket that the poloys are in. Parameters are all in check. Tank is cad lights artisan 70 with ap700 light peaking at 45% power placed 14" above water. Any ideas?
