Buyer's Guide

Shopping for the right goldfish tank can be tricky because there are so many options available. It’s important to keep in mind the capacity of a tank, as goldfish tend to prefer spacious environments. Also, think about whether you want a full aquarium kit with all the essentials, or you prefer just a fish tank that you will later fill out with accessories. It goes without saying that you should always look for products made from high-quality materials that will last longer and that are safe for your fish.

Capacity

Although every case differs, goldfish in general don’t mind having plenty of space at their disposal, so getting them a large tank is always a good idea. Some species of goldfish can become quite big over time, such as the Chocolate Oranda, which can grow up to six inches. However, the size of your tank isn’t the only thing that influences your fish’s growth. Therefore, there is no strict formula that prescribes the exact size aquarium for every goldfish. Generally speaking, tanks ranging from 10 to 20 gallons should be enough for a single goldfish, so having 10-20 gallons per goldfish should be a good starting point. The size of the tank you need will also depend on other factors, such as the presence of plants, gravel, the choice of filtration, and feeding.

High-Quality Design

A good goldfish tank, like any other tank, should feature high-quality construction with sturdy and durable materials. You can choose between glass and acrylic fish tanks, both of which have good qualities. Acrylic is lighter than glass and is generally less prone to cracking. Both glass and acrylic provide a high degree of transparency and offer clear view. Also, low iron combines well with thicker glass as it increases transparency.

Accessories

When it comes to setting up a goldfish tank, you can choose to buy just the tank and add other necessary elements and accessories later, or you can buy an aquarium kit, which already comes with everything you need for a fully equipped goldfish tank. These kits usually come with filters, heaters, integrated lighting systems, food, water conditioners, and artificial plants for a complete aquatic experience.

Filtration

Goldfish tend to produce large amounts of waste and they require high levels of oxygen in the water, so effective filtration is necessary to provide them a healthy and safe environment. However, it’s important to remember that the flow rate shouldn’t be excessively high as some species of fancy goldfish have limited swimming abilities and don’t do well against strong flow. If you wish to increase oxygen levels in your fish tank, consider adding an air stone, which can be attached to an air pump via a plastic tube and which emits additional bubble streams.

Water Requirements

Goldfish prefer soft water, which means that they do well in alkaline environments, particularly if the pH of the water ranges from 7.0 to 7.4. Also, goldfish tend to prefer colder water conditions, with water temperatures around 70 degrees Fahrenheit, so bear this in mind if you are buying an aquarium kit with a preset heater.

Are acrylic aquariums better than the glass ones?

Both acrylic and glass aquariums have their advantages and drawbacks and your choice will ultimately depend on your preferences. Acrylic will be less affected by a collision and it won’t leak, whereas glass is more prone to cracking. On the other hand, acrylic may bend over time and become discolored due to sun exposure, which can’t happen to glass.

Which is better for goldfish - wider or taller aquariums?

Wider aquariums in the shape of a rectangle are generally a better choice than the taller or round versions as they provide a wider surface, which means higher oxygen levels. This is essential for goldfish because they tend to produce large amounts of waste and need proper amounts of oxygen to survive.

How often should you feed goldfish?

You can feed goldfish two times a day. If you notice that the food disappears immediately after being dispensed, you can give them a pinch more. However, you shouldn’t overfeed them as they don’t require large amounts of food, and the food that doesn’t get eaten can make the water cloudy. While they are small you can feed them with small slices of vegetables, but as they grow older it’s a good idea to include other living organisms to maintain a balanced diet.

How do you keep a goldfish tank clean?

Filters keep the fish tank clean by eliminating dirt and waste and they help maintain the pH levels of the water. Therefore, It’s essential to have a good filtration system, which can be achieved by using a biological filter with filter cartridges, which allow for quick changes and promote water flow. Filters can be internal or external and it would be best to get one that performs mechanical and chemical filtration in addition to biological one, as they ensure that the water is clear of all types of waste and they keep chlorine levels under control. Also, it’s recommended to leave the filter running in an empty fish tank for a month before you add the fish to stimulate the growth of beneficial bacteria, which help in handling of the bio-waste. It’s important to remember that filters take up certain amounts of space in aquariums, so keep this in mind when deciding on the size of your tank. It’s also beneficial to do frequent water changes as goldfish produce large amounts of waste, which contains high levels of ammonia. If the levels get too high, they may be toxic for fish, and changing the water often helps keep the ammonia levels under control. It’s a good idea to change 10 percent of the entire tank capacity on a weekly basis if you have a new aquarium, and 25 percent if you have an already established tank. If you have aquarium gravel, you can clean it using a gravel vacuum when you notice dirt and debris. You can also add other fish to help you keep the gravel clean. Goldfish work well with certain types of fish that live in colder water conditions, such as cory cats and plecos. Both of these types are bottom feeders and they can help you maintain a clean tank. Additionally, you can use dechlorinators and water conditioners as they further improve the quality of water. They are particularly useful with pond water or any other type of water that was sourced locally.

What equipment do you need for a goldfish tank?

You’ll need the right gear to provide your goldfish with the best possible home. In addition to filters and water conditioners, you can also set up lights and thermometers, add plants (artificial or natural), gravel, and fishnets. All of this is often included in an aquarium kit, so you can buy everything at once. Since goldfish naturally inhabit freshwater streams, they thrive in places that have vegetation, so it’s a good idea to add plants to your fish tank. If you opt for real-life plants, make sure to choose the type of plants that fits the goldfish as well as the temperature and pH levels of the water. If you have a planted aquarium you’ll need a reasonable amount of light to help the plants grow and produce more oxygen. Aquarium kits often include blue or white LED lights (sometimes both) which can mimic daylight and nighttime conditions to make the environment as close as possible to the natural one. Goldfish thrive in temperatures around 70 degrees Fahrenheit, so it’s a good idea to have a stick-on thermometer to check the water temperature at all times and make sure it’s appropriate for your fish. Another item that’s beneficial to use is a fishnet, for various reasons. In addition to helping catch your fish and keeping other wading pets at bay, fishnets also reduce the amount of waste that can float on the surface, such as food and algae. When choosing a net, it’s best to get one with smaller holes as fish’s fins may get stuck in larger holes and hurt the fish as a result. You can also add gravel, sand or rocks to enhance the look of your tank according to your preferences. These accessories also take up space, which will impact the size of the tank you need, as you’ll want to leave enough space for the fish as well.

How long do goldfish live?

Provided they have a balanced diet and live in proper water conditions, goldfish housed in aquariums can live up to 15 years. Goldfish that live outdoors in ponds can live up to 20 years. The longest known living goldfish reached the age of 43.

How to recognize if a goldfish is sick?

There are several signs of possible disease that are easily noticeable. These include fins that are clamped close to their body, refusing to eat, producing increased amounts of body slime, and losing color. If you notice your fish gasping or spending long periods of time lying at the bottom, they may be feeling ill.

Which types of goldfish can be kept together?

Goldfish that share the same types of fins get along well. Double tail goldfish such as oranda, lionhead, and moore tend to swim slower, as opposed to single tail species such as shubunkin and comets, which are fast swimmers and more likely to get to food first, which is why you shouldn’t combine the two types. In general, goldfish are social animals that prefer living in groups.

Expert tip

You should always pre-soak the food before giving it to your goldfish by mixing it in a plastic cup filled with tank water. Pre-soaked food helps the goldfish’s swim bladder stay hydrated, as becoming too dry may cause death.

Did you know

Although goldfish traditionally have golden, orange, and red hues, they were domesticated from Prussian carp, a type of fish that was gray and green in color.

Conclusion

Goldfish tanks come in various shapes and sizes, so it can be overwhelming to find the right one for your fish, but we hope to have made the process easier by showing you the options above. Finally, whether you choose an aquarium kit or a stand-alone fish tank, make sure to create a thriving environment for your pet goldfish.
