The fantail goldfish is a common variety of fancy goldfish, known for its double tail. Rather than having one standard tail with a top and bottom caudal fin, these goldfish have been bred to have two top and bottom caudal fins, with the top fin being fused along the top. Take special consideration when keeping fantail goldfish in order to accommodate their impaired swimming ability.
