A Glimpse into the World of Fantail Goldfish


These goldfish, a beloved member of the Carassius auratus species, are stunning freshwater fish that have been enchanting aquatic enthusiasts for centuries. The origins of these fish trace back to the selective breeding practices of ancient civilizations, resulting in these charming creatures we know today.

Despite their close relation to wild carp, they have a unique charm that sets them apart. They are an embodiment of elegance and serenity, and their seamless adaptation to human-made environments has made them a favorite among fish lovers.

The Dazzling Appeal of Fantail Goldfish

Their first captivating feature that strikes you is its round, egg-shaped body. Unlike the sleek frames of common goldfish, Fantails sport a charmingly rotund physique, adding a unique aesthetic to your aquarium.


Equally captivating are their double tail fins. This split tail extends into four lobes, creating a visual spectacle that is a delight to behold. From the side, these fins resemble a fan, giving this beautiful being its name. This fish also sports a double anal fin, though its dorsal fin remains singular, rising tall and arching gracefully towards the base of its tail.

Their scales can exhibit a metallic or nacreous finish, adding another layer of charm to their appearance. These scales can present a rainbow of colors, from vibrant oranges and yellows to the purest whites, darkest blacks, and even metallic blues and calico patterns.

Fantail Goldfish: A Symphony of Size and Lifespan


This goldfish is not a small creature. On average, these fish can grow to a length of six to eight inches, with the majority of this length coming from their expansive fins. A full-grown ones can comfortably nestle in the palm of your hand, offering a delightful spectacle.

In terms of lifespan, they are a long-living species. With proper care, they can live between five and ten years, offering you a long-term companion to enjoy.

Caring for Your Fantail Goldfish: A Comprehensive Guide

Caring for your loved one involves more than just feeding them regularly. These fish have unique needs that you must meet to ensure their health and happiness.


Creating the Perfect Home

These creature may not be powerful swimmers, but they still require ample space to thrive. A tank of 10 to 20 gallons per fish is recommended, with 30 gallons per fish being an ideal target.

Water Parameters: The Lifeblood of Your Fantail Goldfish

Water parameters are crucial for the health of your precious. As they are not found in the wild, there is no natural habitat to replicate. However, using their closest living relatives, the wild carp, as a guide, we can create an optimal living environment.

  • Water temperature: The ideal temperature range is 65°F to 80°F, with 73 to 74 degrees being optimal.
  • pH levels: A neutral pH between 6.0 and 8.0 is ideal.
  • Water hardness: Aim for a hardness between 4 to 20 dKH.

Designing a Safe and Comfortable Environment


Your Fantail will appreciate a tank that mimics the tranquility of a calm mountain stream. Begin with a soft sand substrate to protect your fish as they explore and forage. Avoid large pebbles or sharp gravel that could potentially injure your fish.

Incorporate rocks, driftwood, and plastic decorations into your tank design, ensuring there are no sharp edges. These elements provide shelter and hiding spots for your Carassius auratus. Include floating and anchored plants such as hornwort, anubias, or java fern to further enrich the environment.

A Closer Look at Fantail Goldfish Diet

They are opportunistic omnivores, which means they'll eat almost anything you offer them. However, due to their propensity for developing digestive issues, it's crucial to provide them with easily digestible, nutritious food.


Live or frozen foods like brine shrimp, daphnia, and bloodworms are excellent choices. For plant-based foods, try high-fiber offerings like lettuce, blanched peas, or zucchini.

Fantail Goldfish Behaviour: A Peaceful Personality

The fantail are peaceful creatures by nature. They are social fish that enjoy exploring their environment, interacting with others, and occasionally grouping up to swim together. These serene fish are not known for their aggression, making them a joy to observe and care for.

Choosing Companions for Your Fantail Goldfish


Choosing tank mates for your beautiful beings requires careful consideration. While these fish are peaceful, they can easily become the target of more aggressive species due to their slower swimming speed. Suitable companions include other peaceable species such as Ryukins, Celestial Eye Goldfish, Bubble Eye Goldfish, Cory Catfish, Rosy Barbs, Zebra Danios, White Cloud Mountain Minnows, and others.

Breeding of Fantail Goldfish

Breeding them is a straightforward process. With the right conditions, these fish can lay thousands of eggs at once. It's recommended to set up a separate breeding tank where the temperature can be slowly increased to encourage spawning.

Potential Health Concerns for Your Fantail Goldfish

Like all fish, they can suffer from various health issues. Common concerns include swim bladder disease and fin rot. Regular monitoring of tank conditions and a well-maintained diet can help prevent these issues.
