Fantail Goldfish are one of the original fancy goldfish varieties and remain among the most popular today. Their rounded body, flowing double tail and elegant swimming style create a peaceful, eye-catching display that suits both modern aquariums and traditional goldfish setups. Available in colours including orange, red, white, black, calico and bi-colour combinations, every Fantail has its own unique appearance. They quickly become tame, often swimming to the front of the aquarium to greet their owners at feeding time. Compared with single-tail goldfish such as Comets, Fantails swim more slowly and are best housed with other fancy goldfish that share similar swimming abilities.

Given the right care, they grow into beautiful, personable fish that can live for well over a decade. We recommend feeding sinking foods rather than floating flakes to help reduce the amount of air they swallow, which can contribute to buoyancy issues in some fancy goldfish. FAQ How big do Fantail Goldfish grow? Most adult Fantails reach 15–20 cm, although exceptional specimens may grow slightly larger in spacious aquariums with excellent care. Can Fantail Goldfish live in a bowl? No. Bowls do not provide adequate swimming space, filtration or stable water quality. Fantails require a properly filtered aquarium with plenty of room to grow. Can I keep Fantails with Comet Goldfish? It's generally not recommended. Comets are much faster swimmers and can outcompete Fantails for food. Fancy goldfish are happiest when kept with other fancy varieties. Do Fantail Goldfish need a heater? Usually no. They are coldwater fish and are comfortable within normal indoor temperatures in most Australian homes. Consistent temperatures are more important than warm temperatures. How long do Fantail Goldfish live? With proper care, high-quality filtration and a balanced diet, Fantail Goldfish commonly live 10–15 years, with many living considerably longer. Show more
