6 Best Betta Fish Tanks Reviews

In search of the finest Betta Tanks? You’ve found the right place!

The freshwater Betta fish is a really gorgeous species. But, unfortunately, they are not suited to the little fish bowls sold at many big-box pet retailers.

To flourish, Betta fish need privacy. While a 20-gallon tank is too much for them, Betta fish do well in smaller, low-cost aquariums, and this is something you can do with the correct equipment.

Fluval SPEC Aquarium Kit (Best Quality)

It is an aquarium that successfully mixes practicality with contemporary style. The Betta fish in your life may benefit from the clear water and simple upkeep of the Fluval SPEC Aquarium Kit. Filtration and lights have been installed in this 5-gallon tank.

A Betta fish will do OK in a five-gallon Betta tank. This aquarium is ideal for housing Betta fish due to its streamlined design. The pool’s rectangular layout provides an excellent amount of horizontal swimming area.

The aquarium is well-lit thanks to the installation of 37 LED lights. Therefore, it is optimal for less sophisticated plant life.

Fluval SPEC Aquarium Kit, Aquarium with LED Lighting and 3-Stage Filtration System, 5-Gallon

The Spec V’s aluminum accents and etched glass give it a sleek, modern aesthetic that’s easy on the eyes. Furthermore, three different media types are included to meet your needs for biological, chemical, and mechanical filtering.

The backside is where you’ll find the filter and pump beautifully crafted. This extra space is large enough to accommodate a modest heater.

The pump has many power levels, but even at its weakest setting, you may need to baffle the sponge filter to give your beta some peace and quiet as it swims.


  • Sleek design,
  • Wider horizontal swimming area because the pool is rectangular,
  • A three-stage filtration system that is hidden behind a secret storage area.


  • Some Betta fish can’t handle the rapid water flow from the pump, so you’ll have to block it with a plant or sponge.

Tetra Crescent Model Aquarium Kit (Best Price)

The Tetra Crescent is a 5-gallon acrylic aquarium with a beautiful view from all sides (and a terrific RRP)!

If you’re looking for an aquarium with a unique outlook, go no further than the Tetra Crescent. In addition to its sleek design, the tank’s acrylic structure is also seamless. In addition, the 16 LED lights provide a warm glow while being energy efficient.

The quiet and adjustable Tetra Whisper® internal filtering system is completely out of sight. This beautiful betta fish tank is affordable. Furthermore, it seems to have a simple installation process, making it ideal for newcomers.

Tetra Crescent aquarium Kit 5 Gallons, Curved-Front Tank With LEDs

For the most convenience, the flexible plastic cover can bend to fit the round front of the tank.

It’s not hard to put in or take out the Bio-Bag cartridges. The proportions are enough for a variety of fish and vegetation. Stick with easy-to-care light plants since the LED strip may struggle to offer enough light for advanced plants. Acrylic is durable yet more susceptible to scratches than a glass tank. A wider field of view is afforded by the rounded front instead of a flat one.

A narrow opening at the top makes it easy to drop food pellets in for the fish. The lights may be removed without hassle, making routine maintenance much less hassle.


  • Stylish curved shape
  • Affordable price.


  • Due to the construction of the lid/filter portion, it is difficult to swap out the lighting or heating components. This requires drilling new holes in the glass lid to accommodate the new components.

The Marinland Portrait Aquarium Kit (Best Vertical Design)

Cool rounded corners and dual-color LED lighting set this Marineland Portrait Aquarium apart. A magnificent view of the tank’s inside is available in this 5-gallon fish tank.

The tank’s portrait design takes up very little room, making it ideal for use in compact spaces like desktops and sideboards. Additionally, the curved glass and smooth edges are aesthetically pleasing.

Unfortunately for your Betta fish, the tall tanks mean that the water volume that might have been used for the tank’s length instead goes to the depth of the tank. (This isn’t a major problem, but we still wanted to mention it.)

Marineland Portrait Glass LED Aquarium Kit, 5 Gallons, Hidden Filtration

With the flip of a switch, you may choose between a white daylight setting and a blue nighttime setting for the lighting system.

If you slip off the lid and fold back the LED lighting system, you should have full access to the tank’s inside.

A three-stage filtration system with a variable flow rate is in a hidden area at the back of the aquarium.

Betta fish that wander into the filtration area might get stuck, and the pump’s current might need to be slowed down.


  • Switchable day/night LED illumination
  • Concealed filtration for Betta fish care
  • Softened corners


  • The horizontal swimming space is relatively tiny for a 5-gallon tank.

Aqueon Complete LED Aquarium Kit (Larger Aquarium)

Aqueon Aquarium Fish Tank Starter Kit with LED Lighting 10 Gallon Fish Tank

The Aqueon LED Kit allows you to see the interior from any angle. Everything you need to get started is included: A 10-gallon tank made in the USA, an LED hood, a QuietFlow LED Pro Power Filter with a cartridge, a preset heater, pet fish food, a water conditioner, a fishnet, a thermometer. Honestly, what more do you need?


  • Ten-gallon capacity,
  • Glass made in the USA,
  • Stylish aquarium products
  • Cartridge-change indicator light


  • The small diameter of the side columns

biOrb FLOW Aquarium

The biOrb Flow aquarium tanks hold 4 gallons of water and are created with ease of use in mind. The LED lights in the tank, as well as the airstone that circulates air through the tank, are powered by a 12-volt transformer. The liquid bacteria and water conditioner packaged with the biOrb are meant to facilitate the first tank cycling process. Together, a filter cartridge and its accompanying pound of ceramic media keep water in top condition.

biOrb Flow 15 Aquarium with Standard Light - 4 Gallon, Black, 72029

You’ll need to obtain an aquarium heater before you can start caring for your Betta fish (which is often the case when buying tanks).

The transparent construction of this beautiful tank improves visibility and reduces its overall weight (but at the expense of scratching easily). Due to its tiny size, your Betta fish will likely have to live alone (though some shrimp or snails will brighten up the tank).


  • 5-step filtration system
  • Sleek contemporary style
  • Simple to set up.


  • Tank cleaning and basic maintenance might be difficult due to the tiny opening.
  • The LED light is tiny, restricting plant availability

Koller 360° View Aquarium Kit

No matter which direction you’re seeing the Koller 360-degree tropical fish tank, you’ll be able to see its inside. This six-gallon aquarium is constructed from seamless acrylic. A stylish LED light with seven color options provides lighting. Because of its 11-inch diameter, this model takes up very little room and might be ideal for a home office.

A smaller diameter implies less water-to-air contact compared to other designs. In addition, since Betta fish do most of their interactions in the top water, they don’t need such a tall tank; a 6-gallon tank would provide them with more room to swim.

Koller Products 6-Gallon AquaView 360 Aquarium Kit with LED Lighting and Power Filter Clear

Due to its compact size, this style may not be suitable for as many ornamental plants and furnishings as larger tanks. Water may be filtered and cleaned at a rate of 45 GPH by using power filters. The filter cartridges might help you get rid of unpleasant odors in addition to the pollutants they trap. Keeping an aquarium is not complicated with this layout.

In addition, QuickStart, Stress Coat, and other chemical additives to aid in starting are included in the tank. A simple maintenance handbook is included, too (especially if you are new to aquariums).


  • You get a 360° view
  • Affordable


  • The small diameter of the column limits aqua-scaping options, which is a downside despite the great price.

What to Look for When Choosing Betta Fish Tanks

Tank Size

The tank size you want to buy is the first factor to consider. For example, a Betta fish requires at least a 3-gallon tank capacity.

Ideally, a Betta fish tank should be around 5 gallons in volume to provide the fish’s optimal environment for happiness and health. In the next section, we’ll go into all the reasons why bigger is better.

The quality of the water filter

The water quality in a tiny aquarium may get contaminated more rapidly with waste products from fish and other debris. This could lead to dangerously high levels of ammonia and nitrite in the water, forcing you to change the water often and, in the end, kill your fish.

So, instead of focusing on the fishbowl, consider aquariums; you’ll quickly realize that you’ll also need a filter for them.

The ability to keep water’s temperature stable

Betta fish, being tropical, need a water temperature of 75°F to 80°F. A filter will be necessary for this. Small fish bowls should not have heaters since the rapid changes in water temperature might stress or kill the fish.

Plenty of room for swimming and living.

The tank’s additional components rapidly consume available space in a smaller aquarium. Space requirements for things like filters and heaters should be calculated. Betta decorations, plants, and substrate will take up a higher percentage of the volume in a smaller aquarium.

Do Not Put Betta Fish in Bowls, Bottles, or Vases

There’s a common misconception that Betta fish originated in crowded, filthy, and tiny habitats. These assertions are false.

Their native environment consists of huge rice fields, some of which are shallow yet ideal for swimming., It is true, Betta fish have adapted to living in puddles, which are really just little bodies of unclean water. But that’s all it is; they’re just making do with what they have. If you’re not content and in good health, you’re not living.

Keep in mind that water for a Siamese fighting fish has to be purified and changed often. Fish health also depends on keeping the water at the right temperature. Betta fish need both an open swimming room and a place to hide. This is the optimal design for a tank housing aquatic organisms.

It’s heartbreaking to see Betta fish being sold in small containers at certain big-box supermarkets. Unfortunately, some people simply think, “That’ll do!”

If you want to think about it, confining your Betta to one of these containers is like confining a human being to a closet. Even if they “survived,” all that food did was ensure that they were neither happy nor healthy. In order to be a good pet parent, you should provide your animal with a setting that doesn’t stunt their development or decrease their life span.

Final Thoughts

There are certain considerations to make when purchasing a good type of tank. To get a tank that you and the Betta fish will love, you’ll need to understand some behavioral features and (sometimes) biological supplements.

There is a misconception that Betta fish can survive in containers as small as vases. Don’t believe a word of it; it’s completely wrong.
