Fantail goldfish are a popular choice for aquariums due to their bright colors, hardiness, and ability to thrive in a wide range of temperatures. They prefer temperatures between 61°F and 77°F and a pH of between 7.0 and 8.2.

The tank should be cleaned at least once every two weeks, and the glass should be wiped down to remove any excess algae.

Food and Diet

Fantail goldfish require a varied diet to stay healthy and active. They are omnivorous, and their diet should include a combination of meat-based foods such as bloodworms, tubifex worms, daphnia, and brine shrimp, as well as plant-based foods such as lettuce, zucchini, and blanched peas.

For convenience, you can feed them dry flakes or pellets, but it is best to stick with live or frozen foods.

Recommended Tank Size

Fantail goldfish are beautiful fish, but they do require a bit of room to swim. They grow to a fair size and produce a lot of waste, so it is recommended that you start with at least a 20-30 gallon tank for your fantail goldfish.

If you are adding more than one fish to the tank, then you should add an additional 10 gallons for each fish. 10 gallons is the absolute minimum required to house a fantail goldfish, but it is best to start with a larger tank to ensure their health and comfort.

Outdoor ponds are also an option for your fantail goldfish if you have the space and resources to do so.

Proper Water Parameters

Fantail goldfish require a specific water temperature range of 65°F to 72°F, with an ideal range of 61°F to 77°F. The pH should be between 6.0 and 8.0, and the hardness should be in the range of 5 to 19 dGH.

It is important to maintain the water parameters in order to ensure the health and well-being of the fish. This includes regular water changes and monitoring of the water chemistry. With proper care, these fish can live for many years in a healthy environment.

What Do They Need In Their Tank

For the best environment for Fantail goldfish, it is important to create a natural and serene tank. To do this, try to imitate the peaceful atmosphere of a mountain stream. Start by selecting the right tank size for the goldfish to grow and thrive.

Make sure to properly set up the tank, including the right substrate, lighting, and water conditions. When picking out decorations, go for a calm, natural look with things like plants, gravel, and driftwood. With the right decorations and setup, you can create the perfect home for your Fantail goldfish.

Add anchored and floating plants. These goldfish especially enjoy things like hornwort. However, Anubia and Java ferns work well.

Standard filters and lighting installations are mandatory for the equipment. Fantails can cause a lot of waste, and this is especially true if you have a bunch of them. So make sure your filtration system can handle your tank’s bioload properly. Other items, such as air stones and shells, are also welcome.

Choosing a Substrate for Your Fish

Choosing the right substrate for your fantail goldfish is an important decision. An inert substrate, such as gravel or pebbles, is the most popular choice and is preferred by many beginners.

Sand is also an excellent option, as it is more natural for goldfish, and they can spend hours sifting through it for fun. Aragonite should be avoided as it increases the general and carbonate hardness of the water and raises the pH.

Potential Health Problems

Fantail goldfish can be prone to certain health issues. The most common health problems include goldfish ich, swim bladder disease, fin rot, tail rot, and fungal infections. Goldfish ich is a common problem and is caused by poor water quality.

Swim bladder disease is another common threat, affecting their organs and making it difficult for them to process food.

Fin rot and tail rot are caused by poor water conditions and bad bacteria in the tank.

Fungal infections are caused by poor water quality and dirty tanks.

To help avoid these possible health problems, you should ensure that your Fantail goldfish are in the best environment possible.

Behavior and Temperament

Fantail goldfish are peaceful, mellow fish that make great additions to any aquarium. They typically swim around the tank, interacting with other fish, or they may even dig in the substrate.

Fantail goldfish are social creatures and get along best with other peaceful species. While they are among the hardiest of the fancy goldfish, they should not be kept with tropical or betta fish as they may become aggressive.

Best Tank Mates

When it comes to selecting tankmates for your Fantail goldfish, it can be difficult to find the best fit. Fortunately, there are several excellent options for community tanks.

Ryukins, Celestial Eye Goldfish, Bubble Eye Goldfish, Cory Catfish, Rosy Barbs, Zebra Danios, and White Cloud Mountain Minnows all make great tank mates. Angelfish are an interesting addition too, although they require special considerations.

The most important thing is to choose tankmates that have similar water-condition requirements. With the right combination of fish, you can create a vibrant and peaceful goldfish community!

Breeding

Breeding fantail goldfish can be a rewarding experience. To start, drop the temperature of the water to somewhere between 10°C (50°F) and 12°C (54°F). Then, gradually raise the temperature by 2°C (3°F) per day until it reaches between 20°C (68°F) and 23°C (74°F).

It is important to note that fantail goldfish prefer colder water than some other goldfish species, with an ideal temperature of 70 degrees F during the day and 50 degrees F at night. To successfully breed fantail goldfish, it is best to have one male and one female in a breeding tank.

Introducing live food to the tank can also encourage them to breed. With some patience and dedication, it is possible to enjoy the sight of thousands of tiny eggs laid by your fantail goldfish!

Care For The Goldfish Eggs

It is important to breed fantail goldfish in a separate tank to ensure their safety and the success of the spawning process. When the eggs are laid, the parent fish should be removed immediately, as they do not possess parental instincts and will eat the fry. This will help to provide a safe environment for the eggs to hatch and the fry to grow without any further disturbance.

After the eggs are laid, it will take roughly 4–7 days for them to hatch, at which point the fry should be fed. It is important to note that they should not be fed before hatching, as they feed off the egg sac during this time. Once hatched, the fry should be fed one meal per day to avoid overfeeding.

Final Thoughts

The Fantail Goldfish is a beautiful and unique fish that is surprisingly hardy and well-suited for most freshwater aquariums. It is recognizable by its medium size and double/split tail fins, and it is one of the more popular or well-known breeds of goldfish. It is flamboyant, small, and relatively easy to keep, even for a beginner.

With its hardiness and attractive appearance, the fantail goldfish is an ideal choice for any fish enthusiast.
