I purchased a 20 gallon tank and kept nine hermit crabs in it - a combination of Caribbean and Ecuadorian hermit crabs.
The hermit crabs that you could purchase at mall kiosks several years ago were pretty unhappy crabs. This species needs much, much more than a half inch of gravel in a plastic bucket and a dish of water to be happy. My crab habitat involved two substrate types (sand and coconut husk) that were deep enough to allow for burrowing. And burrow they did! My crabs would sometimes entirely disappear for days on end, which ended up being a little boring. But they were fun to watch when they were out and about - they would climb on the branches and rocks that I put in the tank, scuttle around, swap shells, and just sit around looking cute.
Honestly, the most fun part of having the hermit crabs was designing their habitat. If the idea of owning a pet that burrows underground for a good amount of the time doesn't excite you, then you might want to reconsider. But if you like designing terrariums and think it would be cool to see a living creature actually thriving in the atmosphere you create, then hermit crabs are a great option. I had my hermit crabs back when I was in high school and they were a really fun hobby.
Also, don't forget the under-tank heater or heat lamp! These guys need a warm environment. Be sure to do your research before getting any hermit crabs. They need fresh food, specific humidity levels, and much more in order to stay happy and healthy.
