The allure of betta fish, with their extraordinary, vivid, and elongated fins, is truly beyond words. It’s no surprise that they stand as a favorite among aquarists worldwide.

Originally, betta fish, also known as Siamese fighting fish, presented a rather unremarkable greyish-green hue with short fins. However, through the art of selective breeding, we now marvel at a kaleidoscope of colors and forms, including the elegant Veiltail, the striking Delta, the intricate Crowntail, the majestic Halfmoon, and the unique double tails, among others.

Bettas are not only magnificent in appearance but also add a touch of elegance to your home with their vibrant colors and graceful fins. They are considered to be relatively easy to care for compared to other fish. Regular water changes are a must, yet they are generally tidy creatures. The simplicity of feeding them and maintaining their environment adds to their appeal.

When considering the addition of a betta to your household, the primary requirement is a suitable aquarium. It’s crucial to understand that the well-being and happiness of your betta are directly linked to the quality of its environment. Contrary to the misinformation some retailers may spread, confining bettas to a cup is harmful and far from the truth.

Opting for a betta fish is an excellent choice when selecting a fish for your aquarium at home. Their stunning appearance, characterized by long, flowing fins and a spectrum of colors, can significantly enhance the aesthetic of your living space.

An appropriate-sized aquarium is essential for your betta to swim freely, enjoy its surroundings, and maintain optimal health. It’s important to provide a spacious and enriching environment to prevent your fish from suffering or leading a dismal existence.

Nevertheless, finding the ideal aquarium for your new companion might seem daunting due to the plethora of options available. To simplify your search, our team has meticulously reviewed over a dozen aquariums specifically designed for betta fish.

Buying Guide: Best Fish Tanks for Betta Fish

While all the products reviewed above have been carefully selected to meet your needs, you may still need to further narrow down your choice. To make this easier for you, we have created a list of things that you’ll need look into when buying a fish tank for betta fish.

Check the tank shape, because not all models are equal

If you have ever been to a local fish store, you will see that the 5-gallon tanks come in an array of different shapes and sizes. How do you decide which one is right for your betta? To give you a heads up, if you are a beginner in this regard, the taller tanks are not as well-suited as others for a betta.

In their natural environment, bettas tend to thrive better in shallow waters, so when you get a tall tank, the deep water gives your fish less space to swim naturally. Due to this, we recommend that you get a longer tank instead of a taller one.

Do not overdo it with decorative items

While it may look aesthetically pleasing to have a fish tank decorated with numerous artificial plants and stones, please be careful about not overdoing it. No matter what you choose to place inside the tank, make sure that you save some space for your fish, too.

If you visit any online or local pet store, you will find a lot of funky decorations for your fish tank, and your pet may love these, too. However, if you are so keen on the decorations part of having an aquarium, make sure that you have that kind of space in the aquarium of your choice to still allow plenty of room for your new aquatic housemate.

We suggest that you first fill the tank up with the essential items such as the filters, heaters, and gravel. After you are done with these, you can then decide how much space you have left for other things. There are many miniature options of decor that you can choose to get the same effect without compromising on how much space you leave in the water for your fish to swim around.

Buy a tank that comes with a lid

Betta fish have the habit of leaping out of aquariums, so we suggest that you always have a lid on your fish tank. The fish does not realize that there is no water on the outside of the tank, and if you are away for a day or two, you may come home to your fish lying on the floor.

While it may not be easy to stop your betta fish from thinking that he is an athlete or preventing the eventual jailbreak attempts, you can always get a lid to ensure his or her safety. If the tank does not already come with one, you can purchase one separately from any online pet store.

Related Questions

What do you feed your betta fish?

If you are a new parent of a betta fish, you are likely wondering what to feed it for proper growth. Well, bettas love eating pellets, and this type of food can be used as a staple for your fish. There are some companies that make pellets, especially for betta fish, too.

Why must you not overfeed bettas?

It is very important to only feed as much as what is required to a betta. If you feed them too much or not enough food, this can become a problem. You can simply use a pinch of food in the morning and a pinch in the evening, and this is often perfectly adequate. Anything more than that will become waste and create toxins by simply sitting at the bottom of the tank.

What happens if the tank is too small?

Avoid keeping betta fish in a cup or small bowl. They need enough space to move around to be healthy and happy. Please remember that the betta’s home is also his toilet, too, so any waste coming from your betta will break down into hazardous chemicals that will make him or her sick. Providing enough space in the tank allows the filtration system to do its job and keep the water safe and clean for your fish.

What is the correct size for a giant betta?

Giant betta fish are often referred to as “King bettas” and are double the size of your regular betta fish. Due to the difference in size, the giant betta fish require a little more space, so it is recommended that they be stored in a 10-gallon tank at the very minimum.

What is the average lifespan of a betta fish?

The average life span of betta fish is usually 2-4 years old. Interestingly, the length of life of a betta fish is directly related to the environment in which they live, so if you maintain a good and healthy environment inside the aquarium and watch their diet, they can possibly live even longer.

How big do betta fish grow?

Bettas are typically small-sized fish unless the species have some extreme genes. They will usually not grow much beyond 2.5 to 3 inches in length. This is one of the primary reasons why they are so easy to take care of. You do not need to upgrade the tank once the betta grows into a mature fish.

When can we call a betta fish fully grown?

Typically, a betta fish grows into a mature adult at 7 months of age. However, this may also vary depending on the environment and the kind of care you give to your pet. If you get a betta from a fish store, it will usually grow into an adult within six months to a year.
