Building a habitat, caring for, and feeding a crab?

Question

Yesterday I caught a ghost crab at the beach, and I don't know how to take care of it. I have a tank at home but I want to know what I need and how to set it up so that I can let him go before we leave if he needs crazy weird/ expensive things. But like the average how to feed/ what they eat/ what kind of stuff to fill his aquarium with.

* I caught him at night on the shore by rocks. I heard that ghost crabs burrow in the day and run into to ocean at night for air, but I don't know what to do about that.
