I have a pink Goniopora that I have had for a year and a half. Initially I had some receeding but since then I have actually had not only polyp multiplication but I can clearly see the flower pot base has grown. I picked up a smaller(mini) neon green goniopora and placed it in a similar spot. Only getting the receeding. Anyone have experience with Goniopora? Any suggestions? They are placed lower, wedged into some rockwork so I don't get them knocked over or sand in them.
