My biggest crab decided to molt out in the open in the middle of my tank. He's almost all the way out of his shell, and I can see him struggling out of his old exoskeleton.. it's really cool to watch. But what do I do about my other crabs? Are they all going to try to eat him? The other crabs in the tank are all tiny compared to him, I have one more that is pretty big, but he went under last week when I did my tank and he hasn't come up since so I suspect he is molting too. Do I need to worry about the little guys eating a jumbo, or will he be able to protect himself? I can't move him right now.
