How do you help a stressed hermit crab?

Many things can stress out a hermit crab. You should have at least 1 gallon of space per hermit crab. Hermies also need the right temp and humidity which BOTH is between 70 and 80. Most hermit crabs you buy are purple pinchers. They are climbers so have alot of climbing toys such as bark for them (do not crowd the tank) they need distilled water, and SEA salt water as well. you should spray their tank LIGHTLY once a day. and have at least 2 hermies.
