So I have a 55 gallon saltwater, liverock, a few fish and inverts and have been working up to corals. The tank has been running strong for the past 8 months with absolutely no problems, all params in normal range for a reef tank. Yesterday, After talking with my very reliable lfs, I purchased my first coral!!! was extremely stoked and rushed home to introduce it to my tank. 15 minutes after placing it, it looked to be extremely happy and flourishing. This morning even, it looked healthy and full. Now, this afternoon it slowly started to retract all the polyps, and now they are all inside. Im a bit nervous as this is my first and am just looking for some reassurance or guidance on if I need to do anything different. I've attached photos of yesterday and today.
