The claw.
The claw size has nothing to do with the sex of the hermit crab. The small claw is a "feeder" claw, used to rip and tear food and bring it to the crab's mouth. The large claw is used for defense, as well as for holding the food while the crab uses the small claw to pick pieces off to eat. The female crab will have two visible gonopores on the 4th pair of walking legs, and will have pleopods on the side of her abdomen, best seen when the crab is switching shells.
they run and have a claw
You can tell a fiddler crab's gender by its claws. A female fiddler crab has two claws, the same size. A male fiddler crab has one large claw and one small claw.
