I discovered my little guy Sherman did a surface molt the other day. I found him in his water dish. He seemed to be pretty active still and moved to his hut with the other two crabs which is their usual hangout. I read that by trying to move them at that point might be dangerous so I left him there. He's vanished now. I'm not sure if the other two ate him or if he's buried. I don't think I have quite the amount of sand in the tank for him to burry himself, maybe two inches... I don't want to dig around either in case he is buried. What should I do? I don't smell anything funny either... should I wait it out?
