Make their captive lives as close to their wild ones as you can. This can be complicated and can vary between species. Generally, you want to have as big of a tank as possible, lots of areas for hiding, climbing, deep pools, deep moist sand, high heat and humidity, and an extremely varied diet. Hermit crabs eat fruits, meats, seafoods, algae, leaves, wood, veggies, seeds, nuts, and even feces. Of course it's all way more complicated than this, but it would take hours to write.
