Betta Fishes are beautiful and stunning looking fish that can attract anyone who loves to keep pet fish. If you are okay to give these fish some extra attention, then you should buy them.

They are also commonly known as Siamese Fighting fish. As the name itself tells you, they like to live alone. These fish need more space and more air to breathe, and so you cannot keep them in small fish bowls or tanks.

So keeping all these factors in mind, we have curated a list of best tanks for Betta fish which would perfectly fit your requirements. There are 100s of options available in the market, so it is merely impossible for you to select among them. To make things easier, we’ve searched the top-rated and best-reviewed tanks from all over and came up with a list.

Let’s get started!

Factors To Look For When Buying the Best Betta Tanks

Before we move on to the 13 Best Betta tank list and their features, you must know what all factors determine the best Betta fish tank for you. So, here are the factors that would help you make the right choice.

1. Tank Size

It is recommended that you chose a tank that contains at least 5 gallons of water or more. This would give them enough space to swim, and you will not have to worry about them getting agitated.

Also, there are a variety of species of Betta fish, and if you are not aware of them, we would recommend you to research before this. Every species needs a different amount of space, and the tank size would, therefore, depend on the type of fish you have.

2. Tank Heater

Betta fish are a native of Cambodia and Thailand. They like warm temperatures and have survived on such temperatures throughout. Now, you must ensure they are warm enough.
Firstly, you should always keep your tank’s water temperature at least 76 degrees F maintained using a proper heater.

Secondly, if you are already living in places where the temperature is warm enough, you may not need a heater at all. But make sure yet again the temp is 78-80 degrees F.

Keeping a thermometer for both the cases is necessary as you can keep monitoring the tank’s temperature every time.

3. Tank Filter

Every tank is going to get dirty now and then. It will become nearly impossible for the Betta fish to thrive in such conditions. So, it is necessary that you provide a filter to the tanks. Choosing a tank that already has a filter fitted into it could be the best option.

These fish come from a very clear ecosystem, and any negligence could cost them their lives. If at all you are thinking not to install a filter, you will need to change the water of the tank every three days at least. This could work for a while, but it gets a bit hectic in the long run. So it’s better to get a filter installed into it or buy one which already has one.

Tips To Set Up Your Betta Fish Tank

Now that you have selected the best tank for Betta fish, you need to understand the perfect way to set it up, so that your fish can thrive well in the perfect ecosystem.

1. Preparing The Aquarium

So, the first thing that you need to do is wash up the tank in whatever manner you want to clean it initially. Then you need to find that perfect place to place it. It can be your living room, dorm, office, kitchen, etc. Some of the Betta fish tanks require a stand as well depending on the capacity it can hold. All of this would depend on how big or small your tank is.

If it is a big one, you cannot keep it anywhere since it would take up a good amount of space. Whereas, if it’s a small one, it could be kept anywhere you will like putting it.

2. Install The Tank Filter

Every tank comes with different filters and with various functions. So it does require a proper understanding of how they need to be installed. Many packages come with a proper guide and manual that will help you to put the filter in the tank.

If you are still unable to, we would recommend you to watch certain YouTube videos that could help you explain the perfect way to install the filters without any hassle.

3. Set Up The Gravel And Plants

Take out the gravel that you received in the kit along with tank or which you may have brought and wash it properly. After this, spread it down on the base of the tank evenly to set up the foundation.

The plants should be properly put up on the gravel so that it is fixed perfectly. Moreover, ornaments such as the colorful stones or a miniature house, statues, etc. should be fixed in the gravel so that it does not move.

4. Fill The Water In The Tank

Since you have set it all up, you can fill up the tank to a proper level. We would recommend not to fill it since every fish would need some air to breathe for once coming on the top. Especially the Betta fish. There is also the risk of the fish jumping out of the water. So make sure everything is at par.

5. Install The Heater In The Tank

All the tropical fishes need a warm ecosystem. So you need a heater installed in the tank. Some of the aquarium kits do provide one, but some do not. So it’s better to buy a good one along with the thermometer.

Simply install the heater following the instructions in the manual and set the temp to 78 – 80 degrees.
