Yes, because the humidity needs to be a bit above average. Also, they sometimes prefer to drink out of a sponge. You need to have the sponge in a ocean-water dish that is deep enough for the hermit crab to submerse in. Thus giving a choice of drinking from the sponge, drinking from the water itself, or soaking in the dish - which helps with molting and gives the crab a natural option for bathing like he would have in the wild. make sure there are always BOTH fresh and salt water dishes in your crab tank - dechlorinated and de-metalled water is vital to your crab's survival! and the salt water should NOT be table salt! you need ocean salt - like oceanic or instant ocean found in pet stores for aquariums. table salt is harmful to hermit crabs.
Salt water hermit crabs need to live in ocean water that has been properly set up (like a reef aquarium). Land hermit crabs need access to both fresh and salt water but live the majority of their lives on land.
they need dechlorinated fresh water, and dechlorinated salt water made with aquarium salt.
Hermit crabs do need both types of water but they need both water because they need to clean themselves and they just drink salt water.
hermit crabs need to live in 70-80 degree temprature
I'm not so sure if they need a companion, but they certainly enjoy company. If you are getting pet hermit crabs it would be advisable to get three or four, and as hermit crabs aren't too expensive, you should think about it.

No hermit crabs need high humidity (70-85%)
Hermit crabs in captivity cannot mate. Unless you live on a tropical island with wild hermit crabs, there's no need to worry. They were probably just playing.
Hermit crabs need distilled water, and SEA salt water, since they are scavengers they eat fruits and veggies. you also need at least 2 hermit crabs they are very social. They need one gallon of space per hermit crab. Hermies also need 70 - 80 F temp and 70 - 80 %humidity. Research more about hermit crabs plz. . .
