Fiddler crabs, also called Gold Claw Crabs, are named such due to the large claw the males have. The large claw is used for territorial displays as well as to attract the attention of a female. The smaller claw is used for eating and scavenging for food. This crab needs to be set up in a part land, part water environment with plenty of places for it to climb up out of the water. Females do not have the large claw. Be very careful to have a secure lid on any aquarium which contains fiddler crabs, as they are excellent climbers and drying out on the floor is one of the biggest causes of death for these little crabs while in captivity.
These crabs are shipped to us in fresh water, and are kept in fresh water here in our building.
