What is a goldfish tank? How does it work?

Once you've decided to keep a goldfish, the first thing to think about is buying a fish tank. This will serve as a refuge for your goldfish, where it can live safe, healthy and happy.

A goldfish tank will perform well when equipped with basic aquarium supplies such as a good filtration system, good lighting, a gravel siphon, thermometer, dechlorinator, sand, food, and a large net.

It is essential to equip the fish tank with an excellent quality filter since it is the one that eliminates fish waste and other impurities present in the aquarium water. Regular and proper cleaning, proper care and maintenance should be done thoroughly on a daily, weekly and monthly basis.

As long as you have followed the manufacturer's instructions when setting up your fish tank, this would certainly be a good place for your goldfish.

Depending on the type of material and the brand you choose, the sale cost of the fish tanks will also vary. Be that as it may, there are also cheaper models with good quality.

And some of these benefits include the following:

  2. Just watching the goldfish play, roam, and swim can put your mind at ease. In fact, this is one of the reasons that goldfish tanks are displayed in large aquariums located in the middle of a series of holding areas.
  3. Just looking at goldfish can greatly improve your appetite. So if you are feeling down and having trouble finishing your meal, you can take a look at an amazing view of the goldfish tank.

frequent questions

10 best goldfish tanks to provide a comfortable living space (17)

What Fish Go Well With Goldfish?

Goldfish are known to be social among other aquatic species. As a result, owners can expect to be a good fit with many fish. But if I had to make a list of the best goldfish companions, I'd start with these five:

  1. zebra bearded
  2. japanese rice fish
  3. pez platy
  4. pink quills
  5. White Cloud Mountain Elritzen

But you don't have to put other fish with gold fish. Goldfish get along well with other goldfish, so there's no reason not to breed them together. In fact, they are known for their education, which encourages more exercise and better health.

Conversely, goldfish do not get along with tropical or aggressive fish. As such, I would not suggest placing them with Betta fish, even in a large tank. It will only make your bettas angry and cause them to attack the goldfish.

How many goldfish can I put in a 5 gallon aquarium?

Most experts recommend following the rule of one inch of fish per gallon of water. It might sound a bit complicated, but it couldn't be simpler. So if you have a 5 gallon tank, it can hold a total of 5 inches of fish.

In any case, a 5 gallon aquarium is generally considered a small goldfish aquarium. It may not even be enough for a single adult goldfish, considering these fish often range in size from 6 to 8 inches.

Consequently, a person with a large 8-inch goldfish should not buy a 5-gallon aquarium. He wouldn't be able to meet the needs of his larger fish. Instead, these people need a tank that is at least 8 gallons. I would suggest looking into 20 gallon goldfish tank setup ideas, as these fish love to have friends over.

An excellent option would be the Tetra 20 Gallon Complete Aquarium Kit. This filtered goldfish aquarium offers another 12" of fish to fit. It is also one of the most beautiful goldfish aquariums around.

How often should I change the water in the goldfish tank?

The recommended amount is to change 15% of the aquarium water every week. It helps protect the good bacteria in your tank and prevents your fish's habitat from being disturbed too drastically. But this 15% weekly rule is just a guide, as it is subject to change based on certain factors.

For example, the size of your goldfish tank and the number of fish play a role. A good example would be my massive 50 gallon octagonal tank. In this situation, I have to change 15% of the water every two weeks so that the different species of fish continue to live comfortably.

What are the most reliable aquarium brands for goldfish?

As for the most credible and trusted goldfish tank brands, the following brands are just some of the most trusted manufacturers in the world that have been in the marine field for a long time:

  • tetra
  • sealandia
  • Hagen
  • Agua
  • aquaculture

So if you end up wanting to make the smartest goldfish tank investment, the above brands are great options for you.

Acrylic or glass aquarium: which is better?

Both acrylic and glass are commonly used for aquariums. Actually, at first glance it would be difficult to tell the difference between these two materials, as both are quite transparent and capable of holding significant amounts of water.

And it's only when you own literally every type of aquarium that the differences become more apparent.

Cost wise, acrylic is more expensive than glass. Acrylic is more prone to scratches than glass. Acrylic is lightweight while glass is a bit bulky. When it comes to shapes, acrylic comes in a variety of forms while glass comes in limited forms.

And as for the impact resistance of these materials, acrylic has better impact resistance than glass. And in the interest of clarity, acrylic will yellow over time, while glass retains its constant clarity.

Now that you know the clear distinction between the two materials, the decision is yours. As you can see, both have advantages and disadvantages.

How many liters does a goldfish need? What size tank do I need for 2 goldfish?

For comet goldfish or common goldfish, it is highly recommended that you consider an aquarium that is at least 4 feet long and at least 30 to 50 gallons in volume. When it comes to protecting your goldfish, the general rule of thumb here is: bigger is better.

In the meantime, if you're thinking of keeping more than one goldfish in your tank, be sure to add an additional 12 gallons for each fish added to the tank.

How do you set that up?

Here are the instructions for setting up your goldfish tank:

  1. Be sure to keep the aquarium away from heat sources or windows.
  2. Tidy up the aquarium to remove dust that has accumulated during storage. Then add a layer of gravel or sand. If you decide to use gravel, choose the one that comes with grains larger than a pea. The little ones can be dangerous.
  3. Never turn anything on when setting up your devices. Carefully fill the aquarium with chlorine-free water and then you can safely add some aquarium ornaments and plants.
  4. Finally, turn on the device and let it run for about four to six weeks. Please note that it is important to cycle the aquarium completely, as this will help to ensure that a good bed of bacteria builds up; this will be responsible for the nitrites and ammonia present in the aquarium.

How to maintain and clean?

It is imperative to organize a maintenance schedule to clean your goldfish aquarium. This is mainly because you need to perform some tasks on a daily basis and other tasks need weekly or monthly maintenance.

Things you should do daily:

  • Feed your goldfish.
  • Check your goldfish for problems.
  • Check the water temperature.
  • Get rid of large pieces of unused fish food.

Things to do weekly:

  • Clean the gravel with a siphon.
  • Carry out water changes (should be 25%)
  • Remove algae buildup with the help of an algae magnet
  • Check if the device is damaged or working properly
  • Gently wipe the outer surface

Things to do monthly:

  • Cut down the plants you added to the goldfish tank.
  • Analyze the nitrates, nitrites, ammonia and pH of the water
  • Replace the filter according to the manufacturer's guidelines.

Strictly following care, cleaning and maintenance procedures is essential if you want to keep your tank in the best possible condition. In this way you can avoid the dangers of diseases and infections in the aquarium. This would greatly help your pet to stay healthy and happy and extend its lifespan.
