What is in a crabs habitat?
you can put sand or stones in a crabs habitat my fiddler crab enjoys hiding under rocks and other things that he can fit into he will go into and space he can to hide so you can put large stones in for them to hide under. i bought a smalldome kind of thing that has a bottem layer then stones on either side to hold a larg piece on top of it so he likes to go in there cuz he can sit in the water. also you can buy them beds at the pet store they like those. but all crabs need water so put water in it some crabs need salt water and some need normal water and mine needs part salt and part clean.
