How Long Can Hermit Crabs Go Without Food and Water?

The Survival Skills of Hermit Crabs

Hermit crabs live in large colonies so there is no real answer to how long they can go without food and water. They are social creatures that thrive in groups, often found in clusters along the shorelines. When it comes to housing, you can put up to 10 hermits in a 10-gallon aquarium or 4 to 6 in the smallest plastic cage. The key is to provide them with enough space to move around comfortably, as overcrowding can lead to stress and aggressive behavior.

Surviving on Minimal Resources

While hermit crabs do eat, they have minimal food and water requirements compared to other pets. They are scavengers by nature, feeding on a variety of foods including fresh fruits, vegetables, nuts, and even seafood. However, they have the ability to go several days up to two weeks without food. This is due to their ability to store water in the back of their shell, which they use for moisture to keep their gills damp and functioning properly.
