Goldfish, the magnificent beauty of the fresh waters, are considered royalty as they descend from the Prussian Carp. Its ancestors were dull silver, and the first yellow and orange colored goldfish were bred by people in China.
Nowadays, this freshwater fish comes in different colors, size, fins, and textures. It is an ideal companion for an introverted kid who likes to be indoors or an aquarist who wants to keep a variety of fishes.
When it comes to a goldfish, it is essential to know that it grows fast and needs space. It should be kept in the best goldfish tank, (not a fishbowl )containing a heater, freshwater, sand or gravel bed, and enough oxygen.
Goldfish are omnivorous by nature and will eat frogs, larvae, fish eggs, etc. Therefore, it is essential to feed them a mix of veg and non-veg diet so that they do not suffer intestinal issues and die young.
If you are a novice breeder, then feed them with pellets and small cut vegetables which are suitable for a small fish’s appetite. But as they grow, they will need living organisms for food and nutrition.
Why Do You Need a Goldfish Tank?
Goldfish are considered auspicious by some, and for others, it adds to the aesthetic appeal of the house. Unfortunately, what most people understand that a fishbowl is no place for a goldfish to live. A goldfish can grow up to the size of half the fishbowl and needs aerated water to breathe.
It is only possible in the best goldfish tank with clean water, proper temperature, and a wider surface area to get oxygen. A poorly kept fishbowl filled with ammonia sludge will reduce the life expectancy of a beautiful creature, and you won’t be able to witness the marvels of the goldfish.
If you are planning to keep a goldfish, there are few things you need to understand and then make an informed decision:
A) Goldfish lives a long life
A goldfish is a beautiful creation of God that is meant to live in fresh streams. If you are thinking of keeping one then first and foremost understand that given the right conditions it can live up to 20 years (in rare cases 50 years) and can grow up to 10inches. It is not a small fish, but if you stock it in a small fishbowl, you may lose him in 3 months. So, opt for a large size tank to give him a homely and comfortable environment.
B) Grows fast
A goldfish can grow rapidly and faster than a small fish. Generally, people follow one or two inches per gallon rule, but this rule cannot be implied to a goldfish. A full-grown or mature goldfish can be of the size of a softball, and it will need a less crowded and larger sized aquarium. It is recommended to purchase a goldfish tank of more than 10 gallons for one fish.
C) Requires more oxygen
Because it grows faster, it will need more dissolved oxygen. A small fish tank or a bowl with a small surface area will have less dissolved oxygen which will suffocate the fish. It will frequently come on the surface as the dissolved oxygen is more here. That’s why a proper goldfish tank is essential for its health.
D) Temperate, not a home fish
An ideal habitat for a goldfish is a lake or a cool stream with enough space, aerated water, and temperature not above 74°F. It is not a home fish, but if you want to breed it then keep it in clean water which is filtered frequently. It should be kept in a tank with more than 10gallon space with a temperature between 68-74°F.
E) Excretes more than other small fishes
It may surprise many breeders or fish lovers, but a goldfish indeed discharges a massive amount of ammonia. It will deteriorate the quality of water, which can lead to diseases that can reduce its life. If kept in a small bowl or tank without any filtration option, it can be a hazard for the goldfish. A large size goldfish tank will not get dirty quickly and can be maintained every fortnight with filter.
Factors To Look For When Buying the Best Goldfish Tank
An essential factor to consider if you intend to keep a goldfish. These mesmerizing marine beauties age gracefully, rapidly and have a long life. So the size of the tank should be significant to make them comfortable and prevent frequent changing of the tank or tank water.
If you are planning to keep more than two fishes in the tank, you should ideally choose a tank of 20 gallons as it requires less cleaning. Also, it is important to consider the location of the tank; if you are planning to keep it in an office, then a large size aquarium is a perfect choice.
Often, people get confused about whether they should opt for an acrylic tank or a glass tank. Both materials have their weaknesses and strengths; where acrylic can handle collision impact up to a level, glass is susceptible to change.
Glass won’t warp, but over time, acrylic may bend or lose its shape. Acrylic won’t leak, but the glass may leak in case of a crack. But, acrylic aquariums discolor or become yellow if exposed to the sun or if they are too old. On the contrary, the glass will never lose its color.
It is a personal preference of the person, but as glass aquariums mostly come in a rectangular shape, it gives more space to the fishes to swim.
Another factor to consider for the best goldfish tank is its durability. It depends on the material used to manufacture the aquarium which comes down to acrylic or glass.
Acrylic aquariums are durable than glass ones as they can handle the impact of a collision or crack; they do not leak and can tolerate the temperature. On the contrary, glass cannot handle extreme temperature fluctuations.
It is less forgiving the acrylic and will break easily. Glass aquariums are heavier than acrylic and challenging to carry. So, when it comes to durability, acrylic aquariums are considered better and long-lasting, especially when you have kids in the house.
Fish keeping is not limited to owning fish and a fish tank. You need many supporting accessories like fishnet, filter tank, bubbler, stick-on thermometer, heater, food, cleaner, and many other things to maintain the aquarium.
The best goldfish tank will come along with such accessories, and it is an essential factor to consider while buying a tank. While you are scurrying through the numerous options, check the type of fittings required to maintain the tank for a long time and whether they give away these accessories or not.
If it involves a lot of accessories and does not have built-in or complementary accessories, then it is probably not the right choice.
A goldfish needs fresh and aerated water to survive in an aquarium. The filter’s job is to keep the tank water clean, remove the toxic waste, and maintain the pH level of the water. You don’t want your fish to swim in its waste and an aquarium filled with dirty water and foul smell.
There are two types of filters: an internal and external filter to keep the aquarium clean. The ideal one is which has a three-stage process, i.e., biological, chemical, and mechanical. It will clean the water by clearing excrement, chlorine, and other wastes. While buying a filter, also keep in mind the space it may consume.
6) Opening Of The Tank
A pro fish hobbyist will consider the opening of the fish tank as an essential factor. Fish, just like humans, need oxygen and they do swim to the surface to breathe, which is why the tank with a wider surface is considered best goldfish tank than the one with the narrow surface.
If the surface of the tank will be wider, then they will get more oxygen; hence, they can stay in water for long. But, if the tank is tall or round with a narrow surface, then its oxygen capacity will be less, and they will come on the surface frequently, causing them discomfort.
One of the skipped factors to consider while purchasing a tank. Fishnet is a tool that will help to keep your fish healthy in a clean environment. Most people think that it is used to catch the fish or ward of perpetrators, but it has multiple uses.
It helps in skimming waste material floating on the surface, waste food, sifting algae, and mosquito larvae. While choosing a fishnet, opt for the one with small holes rather than the ones with larger holes; and the mesh should not be coarse. Fins or gills of the fish can get stuck in the large holes of the net, which can harm the fish.
Fish enthusiasts love to decorate the aquarium to set up a vibe. But make sure that you don’t harm the fish or use most of the space in the tank, leaving no space for the fish. Ideally, a fish tank should be spacious with clean water, but for decoration, you can add a rock, water flora, lighting, etc.
Keep in mind that lighting is done from the outside or use low profile LED lights for the growth of plants, but make sure it does not give an electric shock to the fish.
9) Gravel Siphon
If you don’t prefer sand but gravel in a fish tank, then make a gravel bed with large size rocks so that goldfish do not eat the small ones. Along with it, you need a gravel siphon as it will help to clean the aquarium by taking out the gravel.
Whenever you change the water of an aquarium, it is important to take out the gravel, and a gravel siphon will do the job. You can get an automatic or manual siphon depending on your preference and budget.
Water temperature of the aquarium needs to be stable for the health and longevity of the fish. The water temperature should be between 70-78° depending on the weather conditions, time of the day, and type of fish. A stick-on thermometer will help in tracking the water temperature frequently and accordingly adjust the heater.
For a person who adores goldfishes, the budget will be the least of his concerns, yet it is a factor that cannot be ignored. If you are new to fish keeping, then start with one fish in a small tank. But if budget is not a constraint and you are a pro, you should opt for the best goldfish tank of considerable size and an established brand.

Best Goldfish Tank: What’s Your Choice?
There are many misconceptions regarding goldfish keeping, which I have tried to address and remove in this guide. I have also reviewed the top eight tanks that can be an ideal habitat for a goldfish. However, it is essential to understand that a goldfish needs room to swim, breathe, and grow up to its full potential.
If not given comfortable and right climatic conditions, it can fall prey to itch and other diseases that can reduce its life to a few months or a year. So, do not blindly follow one inch per gallon rule in case of a goldfish and do not opt for a tankless than 10 gallons.
An important point to note if a goldfish is in your mind then do not overcrowd the aquarium with other marine animals. My top pick from the aquariums mentioned above is SeaClear Aquarium acrylic combo set, as it is classic, clean, and has the capacity.
