History and an overview of goldfish:
Goldfish is a freshwater species in the family of Cyprinidae of the order of Cypriniformes. It is a relatively small member of the carp family, which is native to Eastern Asia.
In the beginning, various carps were reared for food like most of the fishes by ancient Chinese. Goldfish was one of the common fishes eaten by ancient Chinese. In the wild, they were a dull grey or silver grey or olive green color.
The first orange-red goldfish was produced by natural mutation during the period of the Jin Dynasty (AD 265–420). By the 7th-8th century, goldfish became part of the ornamental ponds and water gardens.
During the 17th century, goldfish entered Europe through Portugal, and it first came to North America in the mid-1950s. Before we knew it became the most popular fish in America’s aquarium trade.

Besides the above points, the type of goldfish you want to choose makes a vast difference in the size of the tank to accommodate and the care routine.
The common goldfish, such as a comet, shubunkins, wakins, Jikin, and Watonai, are small when they are babies but can grow over 12 inches(30cms). These common varieties are more suitable in a pond or a large aquarium tank. However, they are hardy and need minimum care.
If you are tight on space, you can choose on the double finned or fancy goldfish kind. Some of the fancy goldfish are hardy and are adaptive, such as Tamasaba, Ryukins, Black moors.
Solitary confinement of the new goldfish is the first step to care for your goldfish:

The reasons are to destress the fish from transportation. And also quarantine them from developing any disease, treat and build their immune system before introducing them into your community tank.

The right filtration tank is the top on the list of equipment to provide a quality home and care for your goldfish. Filtration is not just for filtering out the suspended particles or debris from the water. Your aquarium filter houses beneficial bacterias/enzymes that are necessary to keep the desired water parameters. Beneficial bacteria or enzymes process the ammonia to nitrite and nitrite to nitrate. This process is called the nitrogen cycle.
The level of ammonia and nitrite admissible in the aquarium tank is zero, while nitrate being a less hazardous element and is allowed to build to a certain level (>20 ppm)before you do the water change.
A Heater:
Though goldfish can live in cold water, their immune system can take a thrash as the cold water will stress out your goldfish; it is true more so with fancy goldfish or double-tailed goldfish. The delicate nature of the fancy goldfish has less tolerance level to disease and bacterial infection.
Goldfish immune system is at its best at the water temperature range of 68° to 74° F(20° to 23° C).
Most importantly, stable water temperature is essential in keeping the goldfish out of stress. A heater keeps the water temperature steady.
An Aquarium light:
Aquarium light helps in differentiating the day and night, which is essential for the fish and the other aqua lives to prosper. Visual effects are an added perk of aquarium light.
A test kit:
To ensure good quality of water, testing various parameters regularly is essential. The parameters include temperature, pH, dGH, dKH, dissolved oxygen, ammonia, nitrite, nitrates, etc.
Water changer and cleaner:

Plants and algae help in dissolved oxygen levels through photosynthesis.
Having gravel or sand gives a natural riverbed feel and aesthetically appealing. It also provides something for the fish to forage.

Goldfish are omnivores; hence, they need both animal matter as well as plant matter to keep them healthy. In nature, the goldfish diet consists of crustaceans such as shrimps, crabs, barnacles, etc., insects, algae, protozoa, and other plant matters.
They are opportunistic feeders; they will not stop eating their accord. That is why over-feeding will endanger their health. The selectively bred goldfish have a convoluted intestine tract. Over-feeding also promotes undesirable water quality as the goldfish produce more waste and fecal matter. Most time, it is due to incomplete protein digestion.
Goldfish food-specific feed consists of less protein and more carbohydrates compared to other fish food. It comes in both flakes as well as sinking pellets.
You can also feed them with blanched peas, lettuce, cabbage, and other leafy vegetables. Goldfish will benefit from live or frozen bloodworms, brine shrimps.
Variation is the key to a healthy and balanced diet for goldfish. You can feed with sinking pellets, floating granules, etc. as much as they can eat in 3 to 5 minutes for 2 to 3 times a day.
Duckweed is another good source of protein that contains a trace of minerals, vitamin K, vitamin P, and pigments such as carotene.
Duckweed, brine shrimps, bloodworms, etc. help bring out the bright orange/yellow-red color from your goldfish.

All pets need maintenance, such as clearing the litter, taking out for a walk, occasional vet visits, etc.
Similarly, our goldfish need a routine water change. The filtration removes suspended particles and other solid wastes along with housing and propagating a colony of good bacterias/enzymes. A set of bacterial enzymes digest the ammonia produced by the fish wastes into nitrite, and another kind of bacterial enzyme turns this nitrite into nitrates.
Nitrates are less harmful and allowed to build in the water, up to 20 ppm. Over 50 ppm, it will be harming your goldfish.
A routine partial water change will keep the nitrates level under 20 ppm, which is the desirable level. You can perform this process with an aquarium siphon without bothering your goldfish.
You would want to test the water regularly for all the basic parameters that include nitrate along with pH, dGH, dKH, ammonia, nitrite, etc. If your nitrate level is higher than 20 ppm, you may not be changing the water as much as it requires.
You want to pay attention to how your goldfish swims, where they spend their time, how they look, etc. Isn’t the reason why you got your goldfish in the first place? Watching them can destress you and improve your mood and health.
