Actually it doesn't take very long for a hermit crab to smell when it's dead. They will not smell if they just died. About 10-15 mins they will start to smell. You have to put the hermit crab up to your nose in order to smell the rotten fish smell.
i have hermit crabs and normally they will smell or they will just not move for a long time
Hermit crabs can. It happens when the hermit crab is changing its shell and falls over or when the hermit crab is dead it slides out or falls out of its shell! Sadly they can't always get back in there shells and die.
A Hermit crab can live up to 100 years of age
As long as you're sure your crab is dead and not molting, yes, dig it up immediately. You can boil the shell it lived in and put it back in your tank for other crabs to use.
it never sheds

Hermit crabs should stay in a tub of lukewarm water for around 2-3 minutes. You shouldn't bathe them any longer than 3 or 4 minutes. Depending on the type of hermit crab, there is a possibility that the hermit crab could drown, so watching the hermit crab moving is a good thing. Bathe your hermit crab once a week. If your hermit crab is not used to taking baths, start giving him/her baths once a month and when your crabs are used this give him/her baths once a week. Clean your crab for at least 15 minutes or wait until your crab climbs out of his bathtub.
no as long as you take care of it and you are not overcrowding the tank
However long they feel like it
A long clawed hermit crab protects itself by hiding in it's protective shell or fighting back with its claws, or by putting its body in its hard shell.
