Make sure your water params are good for LPS. Mine is in low to med flow. It sits directly under (10 inches) a 175 10k. It may be getting used to your tank still. If you bought it in good shape and your water and flow are good, just wait it out. I assume you have some descent lighting as well. Mine stays more closed in high flow and gets huge in low flow.
