There are over 20 species of goniopora's, and they are practically found anywhere on the reef. Some gonio's need intense lighting with strong waterflow, while others can do well under low lighting and low flow. It is almost impossible to tell where your goniopora was collected, so my advice is to start on the bottom of the tank and work your way up until it is happy. Also, make sure you feed often, I have notice rotifers work well or anything inbetween the range of 100 - 400 microns. Good luck!
