I was gifted a Xenia frag. When I put it in the tank after acclimating, it got bigger and all the "hands" were open. But over the next few days it got smaller and smaller. Day 1, the hands kept opening and closing all the time. Day 2, the same thing except it got smaller. Day 3, size is now much smaller. My parameter is good (pH 8.2; nitrite 0, ammonia 0, nitrate 5ppm). I dont have Phostpate test kit though. I did 20% water change and it's still the same. :/
