They're very easy though, you just have to give them a couple grapes, and leave some hermit crab food for them. The water just make sure you replace it every day. They can go without food/water for a week if they need too. If you spend most of your time inside, that's better. That's because they need to be inside, next to a window or have a heat lamp. You should never leave them outside. So basically just watch them, play with them, and check on them daily.
