Ok, I'm drunk so pardon any mis-spellings...I'll do my best to correct any errors.

From experience and research fiddler crabs do best in brakish to marine environments comprised of areas where they can crawl out of,(i.e. a large tank set up as a mangrove swamp works great,). Otherwise they die within a week to a month, tops.

Hope this helps.

A 10 gallon tank is great for a species only tank. you will have to get brakish water and the sand should be in a slope where there is a area where they have open air and a area thats with water. I say sand because they come from beaches where they borrow and hide. So i think sand is a must. In a 10 gallon i think you can fit 4 or 5 crabs since they stay small. :D

Edit:


something like this but i never finished with the setup.

oh yea and make sure the tank is well covered because they like to find ways to escape the tank and are preety good at it.

That setup ios in the right direction. I'd make it bigger,(20 or 29 gallong,) so you can add one of those fluval or duetto internal canister filters...makes things nice and shiny...and add a mangrove tree, they're easy and fun to grow. And if you add a freshwater bowl, you can also keep hermit crabs in there with them successfully. In fat, the hermits benefit from the salt water/brakish environment, they need low doses of salt, which is a main reason they die in captivity where they only have fresh water.
