I've kept anemones for over 30 years and have had my current carpet for 20+ years. Its not uncommon for an anemone to take days to find a happy place when introduced to a system. My carpet moved around for weeks before it finally settled. Maybe its the photo but that anemone looks a bit bleached out. I highly recommend avoiding white LTAs and seabaes. They have likely expelled much of their zoozooanthele, and it means they are not in peak condition. Its not necessarily a sign they are going to die, just not a good way to start and might be a contributing factor to its unhappiness. I assume your water quality, temp and lighting is on point. I think we do far too much to intervene and make the process take longer when we move them around, dig holes etc. Only intervene if they are going to get sucked into pumps, drains etc, or remain flopped upside down. Be sure you have your powerheads covered with foam. Set the flow rate a bit lower and dont mess with it because that and the power of the lighting are two major factors in where an anemone decides to settle. For whatever reason, mine always settle under the power heads. Wishing you good luck, hope all goes well.
