Hermit crabs need a tank that provides enough space for movement, humidity, and climbing opportunities. A large tank helps me create a natural environment that supports their health and activity. Choosing the Right Size I found that the size of the tank directly affects the well-being of my hermit crabs. For a small group, a tank that holds at least 20 gallons is a good starting point.
