well you will have to really do nothing a crab dosent die from simple things in the wild its just a part of nature.
Hermit crabs often will lose legs no worrys though!they will grow back when the molt(growth spurt)to encourage molting make sure you have plenty have shells in their habitat to switch to.
You need to have the right humidity, temp, space, acsessories, substrate, ect you should Google how to take care of hermit crabs.
Becuzz it had bad luck
It depends on how healthy the hermit crab is in my opinion
There is not one person who has a hermit crab with a missing leg. I found a hermit crab with a missing leg and even though the store keeper told me that he had a missing leg I still felt I had a bond with him. If you do get a hermit crab with a missing leg you just have to wait until it molts. Once it molts the leg will grow back and it will be like it never had a missing leg in the first place.
It is ok for your hermit crab to lose only one leg in a certain amount of time but if your crab is losing more than one leg a nite put them in an isolated tank because there is a chance your crab may be dying.
you don't need to do anything a hermit crab will do it itself. if a hermit crab losses a leg it will grow back. it will grow back after molting.
I actually did get pinched by a hermit crab earlier today. I did not do anything . You probably felt a little sting but you do not have to do anything. (to prevent any pinches keep your hand flat as you can when you hold your hermit crab)
yes
Yes, but it will die soon.
Yes, a hermit crab will grow its let back if it has lost one when it molts. It's easier to see if your hermit crab has signs of molting. If its lost a leg you will see that the leg will start to turn into a gelatin like substance. Which tells you its going inot the stage of molting.
No, it regrows them

What is a Hermit Crab's predator?
You can if you want to, but you can actually keep it in there and let it serve as another food choice for the hermit crab.
