My Christmas wrasse I just got last week spends most of his time buried in the sand bed. He comes out in the morning when the lights come on and stays out till around 12:30. After that he is gone for the rest of the day. I haven't noticed any of the other fish in my tank harassing it and its eating fine. It's such a beautiful fish I hate for it to spend its time in the sand. Any ideas? Maybe an acclimation box to help?
