Answer 2

Do you have other crabs? If you do they probably got into a fight and that;s how he lost his leg.

Does the place he lives in have sand? If so, he could have gotten stuck and lost his leg.

Do you have big objects or things that are easy to get stuck in the tank? If so he lost his leg by getting stuck.

Thats about all I can say.

Answer 3

How cold is you hermit crab's environment? Crabs have been known to lose their legs when it gets too cold. Just try and find some way to warm its environment a bit. You could try putting a light over his tank, or even putting a warming tray for water. They can be found in most pet stores.
