On Wednesday, November 11 we woke up to find our emerald crab molting. He sat in the same place, working on shedding until Saturday morning. When we looked in the tank he was gone. I have read that they will hide for about a week after molting until their shell hardens. We haven't seen hide nor hair of him since the 14th. We have looked all over and under the rocks and can't find him. I've tried to convince myself that he has buried himself in the sand and to just quit looking for him and he'll eventually come out. Is this normal? How long will he stay hidden? Thanks!
