Keeping Fantail Goldfish in Your Aquarium

Fantail Goldfish are relatively hardy, but they need more aquarium space than their small juvenile size might suggest. These fish grow considerably larger and produce a substantial amount of waste, making good filtration and regular aquarium maintenance essential.

For long-term care, an aquarium of approximately 100 litres or larger is recommended for one adult Fantail, with additional capacity for other goldfish. A longer aquarium with plenty of horizontal swimming room is preferable to a small, tall tank.

Provide a smooth gravel or suitable sand substrate, open swimming areas and decorations without sharp edges that could damage their delicate fins.

Fantails can also enjoy hardy live aquarium plants, although goldfish may nibble or uproot softer varieties.

Maintain good water quality with effective biological filtration and regular partial water changes. Fantails should never be kept in unfiltered bowls or undersized containers.

Fantail Goldfish Temperament and Tank Mates

Fantail Goldfish are peaceful, social fish that generally do well with other fancy goldfish of similar size and swimming ability.

Suitable companions include other Fantails and compatible fancy varieties such as Orandas and Black Moors, provided each fish has sufficient swimming room and access to food.

Common and Comet Goldfish are generally less suitable companions because their faster swimming speeds can allow them to outcompete Fantails during feeding.

Avoid aggressive tropical species and fish known for fin-nipping. Tiger Barbs, for example, may damage the Fantail's flowing fins.

For best results, keep Fantails in a dedicated fancy goldfish aquarium where their particular feeding and care requirements can be met.

Feeding Assorted Fantail Goldfish

Fantail Goldfish are omnivores and should receive a varied, balanced diet designed specifically for fancy goldfish.

Quality sinking goldfish pellets or gel food are excellent everyday options. These help reduce the need for goldfish to gulp food at the surface and allow slower-swimming Fantails to feed comfortably.

Supplement their regular diet with occasional blanched vegetables, such as zucchini or shelled peas, and suitable frozen foods including daphnia or brine shrimp.

Feed small portions once or twice daily and avoid overfeeding, which can quickly affect aquarium water quality.

Are Fantail Goldfish Suitable for Beginners?

Fantails are among the more beginner-friendly fancy goldfish, making them a good choice for fishkeepers prepared to provide suitable aquarium conditions.

They are peaceful, readily accept prepared foods and usually adapt well to established coolwater aquariums.

However, their rounded body shape and specialised fins mean they require more care than their hardy reputation might suggest. Good filtration, adequate swimming space and a balanced diet are important for maintaining healthy fish.

With appropriate care, Fantails can become long-lived aquarium companions that provide years of enjoyment.

Frequently Asked Questions

How big do Fantail Goldfish grow?

Fantail Goldfish typically reach approximately 15–20cm as adults, including their fins. These fish are supplied at approximately 5cm and will require a suitably sized aquarium as they mature.

Can Fantail Goldfish live in a coldwater aquarium?

Yes. Fantails are coolwater fish that generally do well in stable aquarium temperatures around 18–23°C. A heater is not always necessary, provided temperatures remain within a suitable range without sudden fluctuations.

Can Fantail Goldfish live with other goldfish?

Yes. Fantails generally make excellent companions for similarly sized fancy goldfish. Faster single-tailed goldfish, such as Comets, can outcompete them for food and are usually better housed separately.

How many Fantail Goldfish can I keep together?

What should I feed Fantail Goldfish?

A balanced fancy goldfish diet consisting primarily of quality sinking pellets or gel food is recommended. Supplement with suitable vegetables and occasional frozen foods for variety.

Are Fantail Goldfish suitable for outdoor ponds?

Fantails may be kept in suitable protected outdoor ponds in mild climates, but they are generally better suited to aquariums. Their slower swimming ability and flowing fins make them more vulnerable to predators, strong currents and competition from faster goldfish.
