Fantail Goldfish

 

A goldfish becomes the center of attraction of any aquarium, and a Fantail goldfish is sure to catch every eye. An easy-to-maintain variety, even novice aquarists can keep a Fantail goldfish. They are a hardy variety of fish but are prone to a few diseases.

 

The appearance of Fantail Goldfish

 

The Fantail has an egg-shaped body, a long quadruple caudal fin, a high dorsal fin, and no shoulders. Unlike the Shunbukin, the Fantail does not have a slender body.

Their body has either metallic or nacreous scales, and they mostly have non-telescope eyes. 

This variety of goldfish is very commonly found in western countries and bears several similarities to the Ryukin.

However, the fins of a Fantail are not as developed as that of a Ryukin. It has double anal as well as tail fins separated into two matching halves. 

This goldfish has fancy features that make it look different from other goldfish, like Comets. They do not have bubble eyes like the other goldfish.

This trait makes them uniquely different from other goldfish varieties. The bulbous body of the Fantail goldfish gives it a bloated look. Sometimes, a fantail may develop distinctive telescope eyes. It happens after they are six months old. 

One of the most distinguishing features of a Fantail is its paired fins. They have gorgeous double anal and caudal fins that float behind them as they swim. The caudal fins of a Fantail goldfish have four parts.

 

Their name ‘Fantail’ refers to their fin that resembles a triangle when you look at it from above and like a fan when seen from the sides.

Fantail goldfish with very long fins are sometimes also called Ribbontales. However, these long tails bear the brunt of fin-nipping by other fish. 

Fantails are a popular fancy goldfish variant and are bred all over Asia as their natural population does not exist. It is easy to procure this inexpensive goldfish from local fish breeders, and it costs around $5.

 

Fantail goldfish colors

 

The most common Fantail goldfish colors are red, orange, or yellow, but breeders have also developed rarer hues like white, black, calico, and white. You may even find them in the patchy Japanese Koi design.

There are patches of red, yellow, orange, black, and brown in a deep base blue background in Fantail goldfish calico. 

The preferred one among breeders is the Fantail goldfish black with black stripes on the finnage and black spots on the body.

They have three scale types: nacreous (speckled), metallic (solid reddish-orange), and matt (whitish). In the metallic shade, the color is bright and makes the Fantail look polished. 

 

Fantail goldfish size

 

The Fantail goldfish size is 6-8 inches from head to the tip of the tail. The body of a Fantail goldfish is small enough to fit in the palm of a hand, and a considerable part of its size is due to its expansive fins.

 

Fantail goldfish lifespan

 

The average Fantail goldfish lifespan is 10 – 15 years, but if given a well-maintained environment, they can even live up to 20 years in ponds and aquariums. 

 

Characteristics of a good Fantail goldfish

 

A good Fantail goldfish must not have the following :

  • Too long, narrow, or drooping tails
  • Signs of a hood on the head like a Ranchu or Oranda
  • Pointed fin ends
  • The contouring from the nose to the dorsal fin without any bumps
  • Not too light blue or too bright orange color
  • Unstable swimming style 

 

Fantail goldfish tank size

 

Fantail goldfish love to swim around and relish large spaces. The minimum Fantail goldfish tank size is 20-30 gallons, but the more living area they get, the healthier they stay. For every Fantail, you need 8 gallons of water. A large amount of water also helps to dilute the waste.

For a Fantail to attain its full growth potential, it should not be kept in small spaces like a fishbowl. The general rule of thumb followed for goldfish is 1 gallon of water for every inch of fish.  

Since they sometimes swim in groups, a bigger tank is ideal for Fantails. A small tank will result in stunted growth, and a reduced surface area will create an oxygen shortage. An elongated fish tank is better than an oval or round fish tank.

 

Fantail goldfish Tank conditions

 

Fantails love to dig at the tank floor, and any large grains or sharp substance may give them scratches that could lead to infections. Add a soft substrate to the bottom of their fish tank. Try not to add any sharp-edged decorations like driftwood as it may damage their long tails. 

Fantails do not live in the wild, and they need a living environment similar to the one that a carp needs. Carps live in slow-moving rivers with dirt-lined river beds and plants in abundance. Fantail is a hardy variety of goldfish, and you can keep them in a fish pond easily. 

Pick decorations that offer hiding spots but do not overcrowd the fish tank. Keep maximum space free for the fantails to swim around. Plants can act as a shelter for Fantails.

You can add hardy plants like Hornwort that keep the water clean and do not get destroyed by their nibbling or digging. Hornwort can be either planted in the substrate or kept floating on the water surface as long as it does not block the light. 

If you want to add artificial plants, pick silk plants instead of plastic ones. Adding a light to the aquarium is optional, but when you keep goldfish in a tank, you want to see them swimming in a well-lit aquarium. 

 

Fantail goldfish Water condition in the tank

 

Fantail goldfish is a cold-water goldfish species and requires a water temperature of min 60°F, and a maximum of 75°F. Maintain the pH levels of the water between 6 and 8. Although a filter is a must (biological filtration is even better), it is optional to add an oxygen/ water pump. 

If you live in a colder climate area, you must add a heater to the fish tank as sudden temperature drop can prove fatal to this goldfish. The ammonia and nitrate levels in a Fantail goldfish tank must be undetectable. It will prevent them from contracting stress-related health problems. 

 

Cleaning the Fantail goldfish tank

 

Fantails are sensitive to low water temperatures, and you should keep them at a stable temperature.

The water hardness should be in the range of 4 to 20 dKH. You must keep an aquarium test kit to do regular water quality checks. Keep doing periodic checks on the water quality and its temperature. 

Since they are messy and voracious eaters, multiple fantails would mean more cleaning of the water.

Hence they require regular tank cleaning as frequently as once a week for maintaining a healthy environment. You must change at least 10-15% of the water in the tank weekly.

A weekly water change will prevent a pollutant build-up in the tank and keep the fish safe from any infection.

 

Fantail goldfish tank mates

 

Fantails are very social and peaceful fish, and you can pair them with fish that share a similar temperament. When kept with aggressive fish, Fantails may find it tough to fight for food. They can also be easily bullied for their slow speed by fast swimmers.

Since Fantails prefer low water temperature and it limits the number of options to choose from as their tank mates.

You can still keep them in a community aquarium with similar fish. They like the company of other fish and are good explorers.

Most of the time, they swim in the middle of the tank but sometimes venture higher and lower to search for food. 

They often dig up the decorations as they explore the base of the fish tank. Fantail goldfish spend their time swimming around peacefully, scavenging for food in the substrate, and interacting with other tank mates

When choosing Fantail goldfish tank mates, you should keep in mind the water temperature that they need. It is crucial to protect the long fins of this goldfish.

Fantails prefer low water temperatures, and you must pair them with other species that also prefer similar water temperatures and are peaceful slow swimmers like them.

Fish like Tiger Barbs attack the long double fins of Fantail and are not an ideal tank mate for them. As they are slow swimmers, it is difficult for Fantails to escape the attack of other aggressive and fast-moving fish that nip on their fins. 

Tankmates you can consider for Fantails are small shoaling fish, Neon Tetras, Chinese Blue Bitterling, the Northern Redbelly Dace, Zebra Danios, Rosy Barbs, Mollies, Angelfish, White Cloud Mountain Minnows, and Dwarf Gourami.

Fantail goldfish do not shoal but often swim all over the fish tank either alone or in groups. It is the reason why you do not need bottom-feeders for their fish tank.

These fish clean up any leftover food when they swim towards the bed of the fish tank. However, if you are looking for bottom feeder options, you can consider Kuhli Loaches, Corydoras Catfish, or Otocinclus. Keeping multiple Fantails is also a good option as it will be a compatible group. 

Other small invertebrates that you can add to their fish tank include Ghost shrimp, Cherry Shrimp, Amano Shrimp, Mystery Snails, and Nerite Snails. You can also add snails to a Fantail goldfish tank to reduce the algae.

Fantail goldfish food

 

It is crucial to give a healthy diet to Fantails as they are prone to digestive problems because of their compact body structure. Since they are omnivorous, they can be fed almost all kinds of healthy fish food like plant matter and live frozen food.

Feed your Fantails small amounts of food twice a day to make it easy on their digestive system. The amount of food given must finish in two minutes even though the fish may look hungry. Remove Any leftover food from the tank immediately as it makes the water dirty. 

Do not give dried food like flakes frequently as they are low on nutrients. The diet of Fantail goldfish should include high-quality foods only.

To increase their nutrient intake, you can feed them live and frozen foods (moist foods) that retain their nutrients for a long time. Daphnia, bloodworms, and brine shrimp are some excellent picks in this category. The protein content must constitute no more than 30% of their diet.

You can give live plant matter to the Fantail as it contains fiber which is great for their digestive system.

Green vegetables like lettuce and zucchini make for good plant matter and are available at home easily. If you feed the Fantails well, they nibble less on the live plants in the fish tank. Any leftover food can lead to a toxin build-up. 

 

Diseases in Fantail goldfish

 

Fantails are prone to indigestion, and any injuries caused by sharp substances in the tank can lead to bacterial and parasite infections. Ensure that the substrate in the tank is fine-grained and the decorations do not have sharp edges, to prevent any scratching. 

Other ailments that afflict Fantail goldfish include swim bladder disease. It causes buoyancy problems and makes a goldfish either float at the surface or sit on the substrate.

Poor nutrition, constipation, a parasitic infection, or a physical deformity are the primary causes of this disease. Feeding frozen peas (defrosted) to the affected fish helps in curing this ailment in some cases. 

Do not overfeed the Fantails as it could lead to indigestion. Their organs are close together, and this makes indigestion a common problem in Fantails.

Before introducing any fibrous diet like that of vegetables, make them starve for 24 hours. It will be easy for their stomach to digest the food. 

Parasitic and bacterial skin diseases are also quite common in Fantail goldfish. These infections, poor nutrition, and mishandling can cause Cloudy eye disease in fantails.

When a fantail gets infected, there is a visible change in its color and spots. Wounds and ulcers in a goldfish must not be left untreated as they may prove fatal.

Other diseases that may affect Fantail goldfish are:

 

  • Ich- Protozoan disease that makes the fish look salt-covered
  • Costia- Cloudiness of the skin
  • Chilodonella- Blue-white cloudiness of the skin
  • Flukes- Flatworms that infest the gills or body of the fish
  • Fish lice- Argulus. Mite-like crustaceans that get attached to the body of the fish
  • Anchor worms
  • Dropsy – Kidney infection
  • Fish Tuberculosis- Hollow belly
  • Tail/Fin Rot
  • Fungus- Fungal infection
  • Black spot or Black Ich- Parasite infection

You can give over-the-counter medications to the fish in case of a mild infection. You can consult a veterinarian in case the disease persists.

Transfer the infected fish to a separate tank, but do this carefully so that their delicate fins do not get damaged. Sometimes, the body of a sick goldfish becomes extra sensitive.

In case of infection being present in the tank, start the treatment in the main tank itself. If you clean the water in the tank regularly, it reduces the risk of diseases. However, Fantails are prone to falling sick. 

 

Breeding Fantail goldfish

 

Fantails are easy to breed, and breeders conduct a fry selection to produce good-quality Fantails. They can be mated easily in captivity, but the environment must be hygienic. For breeding fantails, you need a specialized breeding tank.

The water temperature of the fish tank should replicate the water temperature in spring. It creates a seasonal breeding trigger for the fish. Change the water temperature gradually so that it doesn’t shock the fish. A daily increase by 3°F a day is ideal, and the temperature should not rise above 75°F.

At the time of mating, the mate starts to circle the female to impress her. It is difficult to determine the sex of a juvenile fantail, but a male is generally more slender than a female Fantail. 

A Fantail goldfish can lay as many as 10,000 eggs that spread around the surfaces of the tank.

The breeding tank must provide a lush environment to the fish. It should have solid surfaces for the spawning process and for the eggs to stick.

You can add oxygenating and bushy plants like Anacharis to the breeding tank. Adding fine-leaf plants or spawning mops helps the eggs cling to them. 

Once the fish lays the eggs, they should be removed and kept in a separate tank to prevent the parents from feeding on them. It takes 5-6 days for the eggs to hatch.

The tiny fry hatched from the eggs must be fed small foods that can easily fit in their mouths. A good fry food option is Infusoria that is high in protein and gives them a growth boost. You can also give them dried crushed food along with fresh food. 

Fantail goldfish are easy to maintain, and even novice fish lovers can venture into keeping Fantails as pets. As long as the aquarium is spacious and the water is clean, this fish thrives well. Fantails are beautiful, and they make a wonderful pet for every fish tank.
