Full Answer

Hermit crabs have only a few simple needs to live a long life. First, they require enough sand or coconut fiber bedding in their habitats to bury themselves completely. Since they are tropical creatures, a warm and humid environment is a must. They need places to hide and things to climb in their enclosures. They need a choice of empty, larger shells as they grow. Finally, it is necessary that they have ready access to a dish of clean, chlorine-free water and, like most animals, need regular feeding.
