Hermit crabs should have a mix of sand and high humidity retaining substrate (such as bed a beast). They also need a heated environment, they are tropical animals.
They need BOTH fresh water (dechlorinated) AND salt water. Table salt is bad, the anti caking agents are toxic, as is aquarium salt as it does not contain true marine mineral amounts.
Hermit crab food really isn't a good idea, you are better feeding a wide range of fresh foods. Hermits love variety.
In the wild hermit crabs travel in huge colonies of up to 100 crabs. This is because it makes it easier for them to find new shells, often they will all start switching shells at once. A lone hermit crab is not a happy animal, the larger the group the better. "2 crabs does not a colony make."
Of course you should have at least a 10 gallon tank for them.
