The record is 32 years.
Marine hermit crabs live underwater and can sometimes be found in tidepools. Land hermit crabs do not live in the water but need fresh and salt water to survive.
In captivity, they live 1-2 years.
I have no idea
No, Hermit Crabs and Fiddler crabs require two different environments. The Hermit Crab would drown in the water a Fiddler Crab needs. You can always ask your local pet store if there is any way possible though. Some hermit crabs live on land others live in water even land hermit need two enter salt water , fiddler crabs are brackish or fresh hermit crabs can't breathe in those environments
Your pet hermit crabs were harvested from the wild, as it is nearly impossible, without a very complex set up, for hermit crabs to hatch and live past the zoea stage. Generally this complex of a setup is only found in scientific laboratories, as one must mimic the fluctuating tides of the ocean. As far as I know, even scientists have an extremely hard time breeding hermit crabs with success in captivity. There are times when one may purchase a female hermit crab that is already carrying eggs, and you may find them in your marine salt water dish (you should definitely have marine salt water available to them, they need it for molting), but they won't survive long if they hatch at all.

In captivity hermit crabs can live longer than 6 years, mine are 3 years old. To learn how to take care of them please follow the link below thanks :)
Land hermit crabs: It's important to have a saltwater as well as freshwater container available in the habitat. Marine hermit crabs: They should only live in salt water if saltwater crabs, or freshwater if freshwater crabs.
Hermit crabs can live for some time without water however it is not recommended and the more time that they are without water the more suceptible they are to disease and death. i have seen crabs live for over a month without water but most do not survive long after that, even when the are moved to ideal surroundings.
