Now here's the pain in the butt, if he's not trying to kick that shell off with in the next few hours then you need to wet him. Now you should only need to wet the part of the shell or membrane against his body. Keep that shell off of him., so all you need to do is take a qtip and wet in a circle around the rim. Do not go inside that shell, sometimes if they don't kick that shell off after a few hours it starts to dry up on there body and stick to them keeping them confined and they can't get out..
