Origin of Comet Goldfish
Native to the rivers and ponds near North America, Comet Goldfish was first found at the end of the 1800s. This fish became popular in the other parts of the U.S. later, and government staffs of America also started breeding this fish in the ponds of the U.S. Government Fish Commission and Washington D.C.
An American pioneer plus government employee of the U.S., Hugo Mulertt started breeding this Goldfish in the 19th century. The name was kept because of the comet-shaped long golden tail of the fish. Today, this breed is globally popular by this name, and fishkeepers like to pet this species in their commercial and residential places.
Comet Goldfish Appearance
As we have mentioned earlier, this fish got its name because of the elongated, slender and golden tail which exactly resembles a comet.
If you have noticed properly then you will find, Comet Goldfish has long flowing fins, but a common Goldfish has inflexible fins. Moreover, this fish is smaller in size than the common Goldfish.
The long heavy fork-shaped tail, single anal fin and slim body of Comet Goldfish make it different to other variants of the family. This fish has normal eyes and flat shinning scales in their body that spark light.
Along with orange, yellow and golden colors, you will find this species in other shades like white-red, brown, black and plain white. Also, the nacreous (cloud-like) pattern and coloration of some Comet Goldfish like Shubunkin Goldfish and other variants are quite attractive.
You can expect Comet Goldfish to grow up to 50% each week. In wild river this fish takes 3-4 years to reach its full size.

Most of the fish hobbyists prefer petting Comet Goldfish in their tank because of its adjustable and hardy nature. Moreover, you don’t require a huge tank for Comet Goldfish, a 50-gallon aquarium is enough to keep this medium-sized fish.
It is fun to watch this bright-colored fish swimming actively with the help of its long flowing fins and slender-shaped body. This fast-moving fish does not like an overcrowded tank because it likes to swim reckless and explore the surroundings of its home. So, keep the tank spacious by keeping fewer fish breeds with Comet Goldfish.

Suitable Tankmates for Comet Goldfish
Although it is a friendly and nonviolent breed, still, it cannot make good tankmates. It is not because of any territorial or less friendly behavior. Comet Goldfish has a tendency to eat lots of foods, so other tankmates can be at risk of malnourishment because of the scarcity of food.

So, try to feed them 2-3 times a day, and also remove the uneaten food from the tank and keep the water condition better.
Never keep the water temperature of the aquarium below 50°F because this fish may be affected by the digestive problem if they eat their food at cold.
Comet Goldfish Tank Requirements
As we have stated at the beginning that Comet Goldfish usually dwells in ponds, lakes, and rivers, so you need to maintain similar water temperature, condition and decoration to give a natural homely feeling to your pet Comet Goldfish. Here are some recommendations by experts which will be required while setting a Comet Goldfish tank:
Bring a 50-75 gallons rectangular tank to keep Comet Goldfish and you will need 200-gallon aquarium to keep a school of Goldfish because this active swimmer needs plenty of space to live and swim.
Comet Goldfish prefers dwelling in an eco-friendly environment surrounded by plants that helps them in hiding and taking rest. Therefore, try to keep some freshwater plants like Hornwort, Anacharis and Java Fern in the tank of your pet fish because aquatic plants will help in oxygenating the tank’s water.
You can also keep small gravels, stone chips and good substrate that is rich in mineral at the bottom of the fish tank. Moreover, keep some hiding caves in the aquarium because your pet fish needs a place for taking rest and hiding from predators of the tank.
Install a power filter in the fish tank to break the down the bacteria inside the aquarium and keep out the waste pollutants and chemicals from the aquarium. If the water of the fish tank is clean then your pet fish will get less affected with health issues that are caused because of poor hygiene.
You will get many aquarium filters in the market but experts recommend two names among them like Fluval C Power Filter and Aqua Clear – Fish Tank Filter.
If you install a water conditioner in an aquarium then it will help in cleaning and conditioning the water by killing the germs which cannot be seen through naked eyes but negatively affect your pet fish. Expert fishkeepers suggest to buy a quality water conditioner for your fish tank – Tetra AquaSafe Plus Water Conditioner/Dechlorinator to maintain the hygiene.
It will be better if you fix a moderate light at the ceiling of the fish tank because too much power may heat up the water of the aquarium which is not suitable for Comet Goldfish, the dweller of cold water. Turn the light about ten hours a day then switch it off at night, which may help in keeping the water temperature normal.
Water Type for Comet Goldfish
Managing the water temperature and range is the most important thing you should carefully follow. Water is the home of your pet Comet Goldfish, so don’t be careless while setting the tank. Follow some essential things mentioned below:
This freshwater fish is generally found from the cold water of lakes and rivers, so it cannot survive in warm water. The ideal temperature of a Comet Goldfish tank is 50-75°F (10-23°C). Moreover, this fish may not digest its food properly if it is kept at a warm temperature.
The pH level of the water should be between 6.5-7.5.
The hardness of the water should be 5-19 dGH.
No need to remove the gravels and fish from the aquarium while cleaning tank water. You can use a gravel vacuum to clean the gravels in the tank.
While cleaning the objects, walls and corners of the fish tank, use a soft brush and liquid soap like API Goldfish Aquarium Cleaner. After washing, wipe out the entire tank and the objects with a soft cotton cloth. Maintaining the hygiene of the tank can help your pet fish live healthy and ailment-free.
If you are changing the water of the tank weekly then you need to change 10% of water but if you change it once in a month then about 25-30% of water is needed to be changed. Always check the temperature, pH level and hardness of the water during the replacement process.
It is necessary to maintain the pH level of the water because if poor quality water with high acidity is kept in the tank of Comet Goldfish then its skin will start fading and its fins will adversely get affected.
Comet Goldfish Breeding
The breeding season of Comet Goldfish is spring when the water temperature is normal in river and pond. However, during the breeding process, keep the water temperature up to 58°F (14 °C) for the first month, and later increase its temperature up to 70°F (21°C) in a gradual process. Also, provide 12 hours light to the fish tank during that time. This will help in triggering the spawning behavior of the fish.
You will find white prickles known as Breeding Tubercles on the head and gill covers of the male fish. The female fish will look fatter than the male with a round belly because it carries eggs.
Breeding of Comet Goldfish is not a very easy task because it requires a spacious tank and suitable water temperature during reproduction. This fish feels uncomfortable to lay eggs in captive, so experts suggest keeping them in a separate tank when the female fish is about to lay eggs.
The male Comet Goldfish chase the female and attempt to touch her stomach while laying eggs. The female fish can release up to 1000 eggs at a time nearby plants or in the aquarium caves.
Once after laying eggs, keep them in a separate tank because the parents can eat the eggs, and if you want to protect them then separate the fries from its parents during the fertilization process. The suitable temperature of the water should be 70°F (21°C) where you will keep the eggs. You can feed small brine shrimp to the school of newborn Comet Goldfish after hatching. Once they become mature, keep them back with their parents.
