In AD 618 to 907 The popularity of carp raises in ornamental ponds and genetic mutation produced gold and people selected Gold carp as goldfish. Now a lot of different types of goldfish are available in the market.
The average lifespan of goldfish is 10 to 15 years, But they can live more years with proper care and water condition. The goldfish can be kept both indoors and outdoors, The most suitable goldfish for outdoors are normal-type goldfish because they can thrive in any water condition, So smaller changes will not affect the health condition of common or normal-type goldfish.
Different Types of Goldfish
There are different varieties of goldfish. Basically, goldfish are three types such as normal type, fancy type, and rare type. Normal types can thrive in any water condition without health problems but fancy and rare types have less lifespan and without proper care and water conditioned tank, the fancy and rare types will not thrive.
Here are some of the goldfish types.

How To Choose A Goldfish?
Choosing a goldfish was an easy task for everyone but you need to select a healthy goldfish for the aquarium. The goldfish must be active in the tank and watch them for 10 minutes for finding any other disease affection. The goldfish need to be healthy, bright-colored, need to be active ( Check they are not staying in one place for a long time).
For aquariums and bowls, you can choose any type of goldfish such as normal, fancy, and rare types, As a beginner, I recommend choosing normal-type goldfish because they are easy to care for and thrive in any water condition.
If you’re an experienced person then choose fancy or rare type goldfish for your tank. You need to check the water quality and water parameters every day and ensure all the goldfish have good health.
For ponds, you can choose normal-type goldfish because they can thrive in any water condition. The outdoor pond temperature can change at any time, So you need to keep a filter and air pump inside the pond for water circulation and cleaning the debris.
What do you need to Setting A goldfish Tank?
For setting up a goldfish aquarium, you need to purchase some equipment listed below. I’ll explain the working and importance of each piece of equipment for the goldfish tank.
- Air pump
- Aquarium lights
- Live plants
- Water parameter test kit
Goldfish need plenty of space for swimming and they don’t need any crowded tank for living. Choosing a tank for goldfish was pretty simple using the rule “ Choose a tank with 10 gallons of water for every goldfish.
If you choose a small tank or a congested bowl then goldfish will not thrive for long because it was hard to thrive in a small tank with low water cycling and low space for swimming, The goldfish may get stressed due to small space. So Don’t look at the money for choosing a tank, try to buy large tanks for goldfish.
The goldfish are grown faster and they need large space for swimming. Slim-bodied goldfish can grow larger than fancy-type varieties. So you need to choose the tank according to goldfish types.
|Tank Size||L x W x H|
|20 gallon High||24″ x 12″ x 16″|
|20 gallon Long||30″ x 12″ x 12″|
|25 gallon||24″ x 12″ x 20″|
|29 gallon||30″ x 12″ x 18″|
|30 gallon Breeder||36″ x 18″ x 12″|
|40 gallon Breeder||36″ x 18″ x 16″|
|40 gallon Long||48″ x 12″ x 16″|
|50 gallon||36″ x 18″ x 19″|
|55 gallon||48″ x 13″ x 21″|
|65 gallon||36″ x 18″ x 24″|
|75 gallon||48″ x 18″ x 21″|

|225 Gallon||72″ x 27.5″ x 27.5″|
Below are the different types of aquariums for goldfish. You can choose different types according to your preference. According to our research, we found that goldfish that live in the small bowl have a short lifespan because of a lot of oxygen cycling
If you put goldfish in a bowl the lifespan of goldfish will be short due to limited space for living. The goldfish requires ample space for living, The bowl is typically small with limited space which can lead to stress and changes in the behavior of goldfish. The Goldfish produce a lot of waste in the tank and the water becomes low quality due to waste.
The Bowl has low oxygenation cycling, It was hard to keep the filter and air pump in a small bowl. So there is no way to introduce oxygen to the bowl and can lead to suffocation and breathing problems.
Tropical Freshwater Tank
The tropical freshwater tank was the best suitable tank for goldfish, The goldfish get a large space for swimming and tropical tanks have advanced filtration and good water condition for improving their health and immunity.
The filtration system will remove all the waste from the aquarium and generate good water flow and oxygenation in the tank. So the goldfish can breathe without any suffocation. It would be easier for controlling the water temperature and other water parameters in the tropical freshwater tank.
Planted aquariums are beneficial for goldfish and offer several benefits for goldfish such as water quality, oxygenation, stress reduction, etc. The live aquatic plants will help to improve the quality of water and absorb ammonia and nitrates. The planted tank was the most suitable aquatic environment for goldfish.
Some of the aquatic plants are the best source of food for fish and it was easier to control the water quality and water parameters in the planted aquariums.
Community tank was not suitable for goldfish because aggressive tankmates will attack them which leads to stress formation in goldfish. You can keep goldfish in a community tank with suitable or peaceful tankmates.
A crowded community tank will not help the growth of goldfish and it would be a hard task to manage the community tank.
How many Goldfish fishes fit in a Tank?
|Tank Size||Water Gallons||Goldfish Count (Fancy Goldfish)||Goldfish Count (Common/Comet Goldfish)|
|20 gallons||20 gallons||1||N/A (not recommended)|
|40 gallons||40 gallons||2||1|
|55 gallons||55 gallons||2-3||1-2|
|75 gallons||75 gallons||3-4||2|
|100 gallons||100 gallons||4-5||3|
|125 gallons||125 gallons||5-6||4|
|150 gallons||150 gallons||6-7||4-5|
|200 gallons||200 gallons||8-10||5-6|

These are different types of filtration for removing debris and other waste from aquariums. Mechanical, biological, and chemical filtration will help to maintain the quality of water in a fish tank.
Mechanical filtration is a process of removing physical waste from the aquarium. The filter will trap the physical particles and maintain the quality of water. Mechanical filtration uses various types of filter media such as a sponge, filter pads, floss, etc.
Biological Filtration is the process of breaking down harmful ammonia and nitrites into less toxic nitrate. The filter media will break down the ammonia and nitrite that was produced by fishes. Ammonia and nitrates are harmful to fish, So the biological filter will break them into less toxic forms.

Aquarium Air pumps are used for supplying oxygen to the aquariums. Goldfish required a good supply of oxygenation in the tank. It was beneficial for goldfish health and water circulation and goldfish stress can be reduced. Sudden changes in the water quality lead to changes in the oxygen level in the aquariums. So you can use an air pump for oxygenating aquariums.

How to set up a Goldfish Tank in 9 easy steps
Now you can set up a goldfish tank in 9 easy steps. Use clean and dechlorinated water for goldfish and check the water parameters according to goldfish preference.
Adding clay layer
Fish tank setting up needs to start with adding a small layer of clay to the bottom. It was used as the first layer for getting a grip on the sand and to encourage live plants in the tank.
Add a small layer means one cm size. Don’t add clay to the fish tank because the fish tank may become dirty. So it will be very hard to clean the water in fish tanks.
In this step, You need to add the sand to the aquarium. Before adding it to the aquarium, you can wash the sand 2 times in water for removing any unwanted waste from the sand.
After that, you can add the sand above the clay layer. Seachem Fluorite Sand 3.5kg was one of the best sand that was recommended by many fish owners. You can choose the sand color according to your preferences.
After adding sand into the aquarium, now you can add gravel into the tank. Before adding the gravel, you can wash it 2 times to remove the waste. Gravel will help to grow good bacteria and it allows water to flow freely rather than on another substrate.
These three steps are simple and easy to do. But the installation of equipment may be a little harder for beginners. Be careful while installing the equipment in a fish tank.
Installation of heater
After adding clay, sand, and gravel to your aquarium, now it’s time to install the equipment one by one. Installing an aquarium heater is pretty simple, you can attach the heater under the water. There are different types of aquarium heaters available on the market.
The important thing is the placement of the aquarium heater. You need to select the heater according to the size of the tank and need to position it at the backside glass. It was not compulsory for the high-temperature areas.
Aquarium heaters are used for maintaining the temperature level in the fish tank. The heater will help to control the temperature as you set it. You can set the temperature of a heater according to the fish’s temperature.
Installation of air pump
Aquarium air pumps are an essential part of every aquarium. Fishes need good oxygen content in the water for breathing.
Otherwise, they will start struggling for breathing oxygen and come to the surface area for gasping air.
Many fishes have breathing problems and without an air pump, they will become stressed and start attacking other fish.
You can use Pawfly 13 Feet Airline Tubing Standard Aquarium Air Pump Accessories for setting the air pump.
Connect one end of the tube to the air pump outlet and install a valve( 2 or way) and connect the air stone at the other end of the tube. You can use a 3-way valve for two air stones.
After all connections, you can place it in the aquarium and hide the tube using gravel or pebbles.
Installation of the filter
Like aquarium air pumps, aquarium filters are an essential part of aquariums. Many beginners don’t know the benefits of aquarium filters.
The aquarium filter will reduce maintenance. After installing the aquarium filter, you need to clean it only once per week.
The aquarium filter will clean the debris and toxic build-up of ammonia.
Without the filter, you need to clean the tank regularly. Otherwise, the water becomes cloudy.
The fishes need good quality water for living. Changing the water regularly was not possible for busy people. So you can install an aquarium filter.
There are different types of filters available in the market. But I’ll recommend buying Tetra Whisper EX 30 Filter For 20 To 30 Gallon aquariums( Link Above Table). It was very easy to install and efficient cleaning.
The installation filter was pretty simple, you can see the installation guide in the manual. Fix the filter on the glass and make sure the intake valves are underwater.

Adding stones and driftwood
After adding live plants into the aquarium, it’s time to add stones or driftwood for decoration. Many people use stones and driftwood for creating a beautiful aquatic nature in the tank.
Before adding stones and driftwood, you need to wash them with potassium permanganate and add small live plants to the stones and driftwood.
Don’t over-decorate the aquarium because many fishes need a lot of swimming space. So if you add more decoration, they will become stressed.
Installation of light
It was the last step in the setting goldfish tank. Installation of light is easy, You can buy hygger 14W Full Spectrum Aquarium Light.
You can select the size of the aquarium light according to the size of the fish tank.
Place the light on above the glass and fit it on the side glass. Make sure that the wire was not touching the water.
Can filter need to be on every time?
All equipment except the heater needs to be on every time. The heater needs to use according to the season or temperature variations. Filter was essential for every fish tank for cleaning the dirt and debris.
They will help to reduce the toxic growth of ammonia in the fish tank and also they will provide good quality water. You need to clean the filter sponge thrice a week.
How to maintain a fish tank
I have seen that many people start fish-keeping and quit after some months. I started fishkeeping to reduce stress and to entertain life. Fishes are the most adorable animals in the world, If your have frustrated then you can go near the tank and watch the fishes.
Maintenance of the fish tank was a little harder. You need to change the water once a week. Drain 80% of the water from the tank and refill it with fresh water.
Every month, you need to clean the tank by removing all the equipment and materials from the tank. Otherwise, the water becomes cloudy and fishes become stressed in the uncleaned tank.
