Can Fiddler crabs live outside of water?
Recognized by their one oversize claw, fiddler crabs are a small, active, easy-to-keep pet crab. Despite how you might find them in pet stores, fiddler crabs won’t be happy or healthy in a completely underwater home. Fiddlers need to be able to climb out of the water and get some fresh air.
How much water do fiddler crabs need?
To mimic their natural habitat, fiddler crabs in captivity need brackish water and a dry land area in their aquarium. You can create this by sloping sand down from one side of the tank to the other. Then, fill the tank so that water covers roughly half the sand. The water only needs to be a few inches deep.
Why is my fiddler crab not moving?
In the wild, fiddler crabs need to be cautious during a molt, since they are highly vulnerable to predators. A few days before molting, your crab may become less active, find a place to hide and stop feeding. This is normal, healthy behavior, and you should not move or try to touch your crab during this time.
