The Basics:
The Fantail Goldfish is one of the oldest and most popular varieties of fancy goldfish. They originated from China and Japan where they still breed them for new colors and shapes. Goldfish are some of the most commonly kept aquarium and pond fish because they are easy to care for and fun to have.

Fantail Goldfish are constantly foraging and begging for food; therefore, care should be taken not to overfeed them. This also makes them very easy to feed. They will accept flakes, pellets, and if outside will eat mosquito larva.

The only challenging part of having Fantail Goldfish is keeping them in a large enough tank with high quality filtration. Too often they are kept in bowls with no filter which shortens their life span considerably. Fantail Goldfish will live up to 20 years if cared for properly.

The Fantail is distinguished by its split tail fins. It has an egg-shaped body that can grow to be the size of a tennis ball (3" in diameter) with fins expanding even longer. Fantail Goldfish get their name because their two tails look like a fan when viewed from above. Common color varieties include red, orange, and calico.

Goldfish are peaceful fish that are very social. They go well with other cold water round bodied goldfish like Ryunkins, Orandas, and Moores. Although they get along with long bodied goldfish they can't compete for food and therefore shouldn't be housed with Comets, Koi, or other long bodied goldfish.

Fantails are cold water fish and need to be housed in unheated tanks or ponds with other cold water fish. Because they are always active and generate a lot of waste, a well-filtered, well-oxygenated tank is a must. Fantails will do well in an outdoor pond as long as they have some shade to avoid direct sun and the temperature doesn't get above 78 degrees.
