Habitat, Tank Conditions & Setup

If you’re looking for a hardy fish popular among aquarium enthusiasts, the fantail goldfish is the perfect option. As one of the most popular types of fish in the aquarium trade, these fish are adaptable and tolerant of various water conditions. 

You will need a tank measuring at least 20 gallons or larger to house two fantails goldfish comfortably, but they do well when kept in groups of six or more. They prefer warm water around 65 to 72 degrees Fahrenheit and should be fed a low fish diet.

Aquarium Size

Look no further than the fantail goldfish if you’re in the market for a small, beautiful aquarium fish. A fantail goldfish will live in water up to 18 inches deep, and as such, they require a tank/aquarium that is of at least this size. 

They are active swimmers and need plenty of space to swim around – make sure to buy a large enough tank to accommodate their needs! Another thing to remember is that fantail goldfish are picky eaters; make sure to feed them fish-friendly food. Also, socialize your fantail goldfish with other fish – Siamese fighting fish are perfect candidates.


These fish require a substrate made of sand, gravel, or rocks, and they will live for around ten years when kept in good conditions. They should be placed in an area with plenty of hiding spaces and plants and a water temperature of 65 to 72 degrees Fahrenheit. Make sure to provide them with food and water quantities appropriate for their size and monitor their water temperature regularly.


Whether you opt for live plants or not, adding some foliage to your fantail goldfish’s aquarium is a great way to add color and interest. Fantail goldfish are of the tropical fish variety, so be sure to provide them with food and water that matches their natural habitat – keep in mind that they do well when kept in groups. In addition, select plants that will not require frequent water changes, for instance, java ferns and anubias.


Fantail goldfish are considered daytime fish and need artificial lighting to thrive. They do well when kept under regular light, but they will require a higher level of light at night to avoid becoming too inactive. A 10-watt bulb should be sufficient for your fantail goldfish’s needs. Additionally, be sure to place plants near the light to get some UVB lighting.


Goldfish are prone to absorbing toxins from their tank water, so keeping their filtration system clean and up-to-date is essential. A beginner’s setup can include a power filter, gravel cleaner, and chlorinator – make sure to change the filter media regularly. Furthermore, rinse the aquarium filter and water change container after each use, as goldfish are known to accumulate debris in their filters.

Typical Behavior & Temperament of Fantail Goldfish

As a tropical fish, your fantail goldfish will enjoy spending time in the water and chasing aquatic creatures. They are considered easy-care fish that do well when kept in an aquarium with other compatible fish species. Fantail goldfish can get along with other types of fish if given adequate space and suitable food. 

In addition, be sure to monitor your fantail goldfish’s water temperature and pH levels, as these can fluctuate greatly depending on their environment, affecting their behavior.

Are Fantail Goldfish Good Tank Mates?

Goldfish are social fish that enjoy living in groups. If you have more than one fantail goldfish in your tank, be sure to provide them with adequate space and plenty of enrichment material (i.e., pebbles, flakes, etc.). Additionally, ensure to feed them a diet high in vegetable matter since they do not eat much fish.

What Should I Do if My Fantail Goldfish Is Sick?

If your fantail goldfish is sick, you should consult with a veterinarian as soon as possible. In addition, you should quarantine the sick fish in its tank and change out all of the water in the aquarium twice a day. In addition, you should feed the sick fish small amounts of flakes or liquid food every couple of hours.
