I finally just got my goniopora that I ordered last week. It was described as 7.5"x9.75", but the skeleton is only 3.5" in a perfect half sphere. Will it stretch that far? When it arrived, it was upside down in the bag, and a little slimy. The polyps that weren't on the bottom are already open, but the others are opening kinda slowly. How long should it take to open? How much flow should it have to fully expand and be happy?
