Betta fish, also known as Siamese fighting fish, are a very popular choice in aquariums. They are colorful and have magnificent fins that improve their character as well as that of the fish tank.

However, the “fighting” in their name is not placed there by accident. They are known to be highly aggressive when housed in the same tank with other fish. This is especially true for the males because they are very territorial.  

Therefore, it is important to consider a tank that can house a single betta fish, some decorations and plants comfortably.

1. MarineLand ML90609 Portrait Aquarium Kit

Editor's Rating: 4.2 out of 5 stars (4.2 / 5)

MarineLand ML90609 Portrait Aquarium Kit
  • Tank Size: 5 gallons
  • Dimension: 11.8 x 11.6 x 17 inches
  • Material: Glass

MarineLand’s ML90609 is one of the best 5-gallon betta fish tanks because it provides a healthy environment for your fish to live comfortably.

The tank is designed in a portrait profile and this makes it possible to grow different tall plants such as Rotala and Cabomba on the inside to improve the fish’s environment as well as the general appearance of the tank.

Above it, the aquarium has a set of LEDs that are meant to light up the fish and all other contents inside in two ways. First is a bright white light that creates a shimmering sunlight effect and the other is a blue light that creates a moonlight kind of glow to simulate the real night time.

These light settings can be easily toggled from one to the other and give you impressive views of the betta fish while also simulating the pet’s natural environment so as to regulate its feeding and sleeping.

Other features include a 3-stage filtration system with an adjustable-flow filter pump, a sliding glass canopy for easy access when feeding and a rounded glass corner design that gives you continuous views of the fish inside.

Collectively, these features make this the top-rated betta fish tank on this review.

Pros:

  • Portrait design makes it possible to include tall plants inside
  • White and blue LED lighting
  • 3-stage filtration system

Cons:

  • Glass construction makes it very brittle
  • Quite heavy due to the glass body

2. Marina LED Aquarium Kit

Editor's Rating: 4.2 out of 5 stars (4.2 / 5)

Marina LED Aquarium Kit
  • Tank Size: 20 gallons
  • Dimension: 24 x 12.5 x 16.5 inches
  • Material: Glass

This aquarium may not have a portrait design but it is wide and tall enough to support tall plants so as to create an ecological environment for the fish.

It has a massive 20-gallon reservoir that is big enough for including multiple plants, decorations, gravel and other things for the betta fish inside.

The kit comes with several items to help you get started. These include fish food, an aqua plus water conditioner, a cycle biological supplement for maintaining a healthy water environment and a care guide to help you set up and maintain the tank.

This makes it ideal for beginners since the startup process is simplified with these accessories and explained well enough for hustle-free fish keeping.

For filtration, Marina’s aquarium features a slim filter that does the mechanical, chemical and biological filtration in one. This basically means that it gets rid of debris, discolorations, odor, pollutants and toxic ammonia, leaving the fish in a very clean and habitable environment.

This same model is available in a 10 and 5-gallon option, just in case you find the 20-gallon tank to be excessively big.

Pros:

  • Large water tank
  • Comes with multiple accessories
  • Mechanical, chemical and biological filtration done from a slim filter

Cons:

  • Quite heavy
  • Occupies a lot of space

3. Fluval Spec V Aquarium Kit

Editor's Rating: 4 out of 5 stars (4 / 5)

Fluval Spec V Aquarium Kit
  • Tank Size: 5 gallons
  • Dimension: 17.2 x 10.6 x 6.3 inches
  • Material: Glass

Fluval’s Spec V is a well-lit fish tank because it features a powerful 37 LED lighting system that transforms the submerged betta fish, plants and gravel into a work of art.

This powerful lighting on such a small tank further contributes to the spectacular views since everything is perfectly lit due to being in close proximity to the light.

Apart from this, the tank is equipped with a 3-stage filtration system that consists of a porous foam block, activated carbon and BioMax bio rings for carrying out mechanical, chemical and biological filtration.

This system is coupled with a powerful circulation pump that ensures the water is clean at all times by pumping large volumes of it through the filters at all times.

Construction wise, the structure is made of clear and etched glass, with aluminum trims on some of its edges.

The trims might affect the visibility of the fish from certain angles but they make the tank stronger and more durable.

Pros:

  • Powerful 37 LED lighting
  • 3-stage filtration system
  • Powerful circulation pump

Cons:

  • Non-continuous views of the fish due to aluminum trims
  • Glass construction makes it quite heavy

4. Penn Plax Aquaponic Betta Fish Tank

Editor's Rating: 4.1 out of 5 stars (4.1 / 5)

Penn Plax Aquaponic Betta Fish Tank
  • Tank Size: 0.5 gallon
  • Dimension: 3 x 3 x 8.6 inches
  • Material: Plastic

Not all good things come in big packages. Penn Plax’s unit is a self-sustaining aquaponics system comprising of a small aquarium for betta fish and a plant growing pot at the top.

The plant basically acts as a biological filter that consumes the ammonia produced by the fish. This results in a win-win situation because the plant gets its nutrients from the betta fish while the fish gets purified water to live in.

However, you will still have to change the water every once in a while since the unit does not have a mechanical or chemical filter. On the Brightside, the lack of this filtration machinery makes it the most affordable fish tank in this list

Construction wise, the product is made using plastic (acrylic), which is very lightweight. Coupled with its small size, the tank is very light and this makes it easy to move it to where there is light so that the plant and fish can absorb some of the light and heat required for survival.

Pros:

  • Aquaponics system for biological filtration
  • Affordable
  • Lightweight

Cons:

  • Extremely small.
  • Does not have a mechanical or chemical filter

  • Dimension: 7.2 x 8.5 x 9.5 inches
  • Material: Plastic

The base platform is equipped with 4 white LEDs that provide a base lighting for the tank. This means that you have to use glass marbles instead of gravel for the tank’s floor so that the light can pass through to light up the fish and water.

Powering these LEDs can be done either by 4 AA batteries or USB port, making it possible to have the fish tank glowing even after the mains go off.

The unit does not have any installed filtration system and this means that you have to change the water every once in a while. However, lacking this system makes it very affordable while its small 1-gallon capacity makes it very easy to maintain.

  • Dimension: 4.2 x 11.5 x 7 inches
  • Material: Plastic

If you prefer keeping more than one fish, the Penn Plax is the best betta fish aquarium for you.

Of course, bettas should not be kept in the same tank so this unit is designed with 3 divided compartments with removable opaque dividers. This means that you can keep up to 3 bettas at a time.

Other than this, the product features a built-in under-gravel filtration system, which requires an air pump and tubing to be bought separately and connected so as to make it function.

However, it comes with Pro-V crystals that help in the filtration process by absorbing the fish’s waste so as to maintain a healthier water environment.

For lighting, this tank features a 2-colored LED system that comprises of a white light for creating a shimmering sunlight effect and blue light for simulating the moonlight underwater. This gives you the option to light it up depending on the mood that you are in.

In terms of filtration, this aquarium has an efficient 3-stage filter that does the mechanical, chemical and biological filtration while neatly hidden inside the column pedestal. This helps maintain its simple but elegant appearance from the outside.

How to Buy the Best Betta Fish Tank

How to Buy the Best Betta Fish Tank

1. Tank Size

Bettas can be found naturally in the shallow streams and rice paddies of South East Asia. This means that they can survive in a small volume of water.

That said, these fish are majestic and require the best environment to grow and flourish. Such an environment includes a large tank, which is recommended to be about 3 – 5 gallons in capacity. The bigger the tank is, the better.  

However, it is important to also consider the space that you have at home. The larger the tank is, the larger the space that it will occupy.

Therefore, before buying a betta fish tank, it is best to consider the biggest one that can fit in your space.

2. Shape

An aquarium’s shape is important because of the view. Normally, square or rectangle faced tanks have a limited view as compared to rounded faces. Rounded faces also look much better because their design is a bit unique.

This, however, cannot be said to be the best tank to buy. People have different preferences and thus, whichever shape looks good to you is the best for you.

3. Material

Betta fish tanks are usually made from glass or plastic. In fact, all fish tanks are made from either one of these materials.

Glass tanks are very clear and maintain this clarity all through their lifespan. They are also scratch resistant, which means that you can use tough scrubbers to get rid of stuck stains inside.

On the downside, glass is very brittle and requires very gentle handling. Glass is also heavier and costs much more than plastic.

Plastic tanks are much stronger than glass; they do not break or crack easily. They are also affordable and very lightweight.

However, plastic scratches easily and might discolor overtime, obstructing the once clear views to the fish, water, plant, and décor inside.

Buying Advice: if you are on a budget, a plastic aquarium will do. If you can afford it, buy a glass aquarium because it is the best option.   

4. Filtration

Even though bettas originate from still waters, it is important to have a filtration system for your tank so that the fish can live stress-free.

Aquariums with 3-stage filtration systems are the best ones to buy because they provide a complete filtration process, leaving you with very little maintenance work. However, they require a constant power supply and are quite expensive.

2-stage filtration systems are the next best option, leaving you with the task of changing the water every once in a while due to ammonia build-up.

Aquaponics aquariums and filter-less tanks are ideal for people living in areas with an erratic power supply system because they require no mains power to function. However, they require a lot of maintenance work in terms of changing the water regularly.

It is important to note that even with a filter-less fish tank, you can buy a separate filtration system and run it alongside the fish tank so as to reduce your maintenance work.    

5. LED lighting

LED lighting is important for two reasons. First, the light is important for showcasing the fish’s bright colors and fins in the best way possible against a background of plants and decorations.

Second, bettas need a good feeding and resting pattern. White and blue LEDs are important for this because they create a sun-like shimmering effect to simulate daylight when the fish can eat and a moon glow effect to simulate the nighttime when the fish can rest.

Thus, LED lights, and especially a combination of white and blue lights, are important for a betta's health and should be considered before buying any tank.

However, they can also be bought separately if your tank does not feature them.  

Tips for Setting up the Betta Fish Tank

Tips for Setting up the Betta Fish Tank

After you have found the perfect betta fish tank, setting it up is the next important thing that you should do. The most important steps in this process include the following. 

1. Finding a suitable location

The perfect spot for a betta fish tank is close to a window because of the light. However, make sure that it is not under direct sunlight and is out of reach from other pets in the house.

2. Set the filter pump to low speed

A water filter is vital for a betta’s survival in the tank. It will maintain the water quality at optimum levels that are conducive for the fish’s survival.

However, the pump running the filter should be set to low speed because bettas are used to gentle water currents. If you want to buy an external filter, ensure that it has adjustable water flow settings or is labeled as gentle.

3. Fill the tank

Add the dust-free aquarium substrate, set up the plants and decorations, and fill the tank with water. After this, run the filter just to make sure that it works.    

4. Install the water heater

Bettas are tropical fish that do well in water that is between 78 and 82ºF. Therefore, you need to install a water heater near the mouth of the filter for even water heating.

Use a thermometer to ensure that the heater works effectively at maintaining the temperatures at this level.

5. Add the dechlorinator and conditioner

Finally, add the required dose of a water dechlorinator and conditioner so as to treat the water and make it safe for the fish. After this, you can put the betta inside and let it take in the new environment.

Conclusion

Betta fish are good choices for fish beginners. Generally, they require smaller aquariums as compared to other similar sized fish and thus, finding their tanks is easier and cheaper.

By going through this article, you will find a variety of option to choose from and the described features will help you pick the perfect fish tank to suit your needs.
