10 Best Betta Fish Tanks – Things to Know before Buying

Best Betta Fish Tank - A Guideline
By Pranay Das Updated

Bettas are undoubtedly one of the most popular freshwater fish among aquarists across the globe. Feisty by nature and magnificent in appearance, they have dominated the fishkeeping business for a while now. As such, the demand for an ideal tank to house them is also very high in the market. And that is exactly what we are going to get into today. Presenting before you our hand-picked list of the best Betta fish tank along with their key features and what do we like and dislike about them.  So, let us get straight into it.

Things to Remember While Buying a Betta Fish Tank

Before we reveal the list of best Betta fish tanks, let us help you identify the key points you need to bear in mind while buying one.

Tank Size

Don’t let the small size of Betta fool you into thinking that they need a small tank. This is because they are a highly active species who love to swim in the open. A minimum of 5-gallon tank is needed for a single Betta. In addition, ensure that the tank has a lid since this fish is notorious for jumping out of the water. Keep a gap of 4” (10 cm) between the water surface and the tank lid.

Nature of Lighting

You have to provide light to your Betta for 12 hours of the day and make sure that the rest of the day, the tank remains relatively dark. Also, don’t place the tank under direct sunlight.

Filter

Since Bettas prefer low current in their water, go for a tank that has a filter with an adjustable flow rate.

Ornaments

Tanks with ornaments are well-suited for Bettas since they serve as perfect hiding spots for them, especially for female Bettas.

Presence of Flora

Including plants help in keeping the ambiance of the tank similar to the natural habitat of Bettas, which ultimately makes for a comfortable petting experience.

Water Type

The water of a Betta tank should have a temperature of 74-80° F (23-27° C) along with a pH level of 6.8-7.4. The general hardness of the water should be 7-9 while the carbonate hardness should be 5-8. Besides, the level of ammonia (0 ppm), nitrate (0 ppm), and nitrate (<20 ppm) should also be maintained.

Best Betta Fish Tanks – Which One to Buy?

Due to their immense popularity, various manufacturers have tailor-made tanks for them. Now, you may be confused which one to opt among them since at a single glance, they more or less, seem to offer similar features. But if you look closely, you will get to notice the nuances that separate them from one another.

Based on our extensive market analysis, product description, and customer reviews, we have compiled our list of the following Betta fish tanks. Also, as an added bonus, we have included our editor’s choice among them.

01

Marina LED Aquarium Kit – Editor’s Choice

When it comes to Betta fish tank, there is nothing that can remotely come close to what Marina LED Aquarium Kit offers. Coming in three different sizes for you to choose from – 5-gallon, 10-gallon, and 20-gallon, this product is equipped with a bright white LED light and an efficient and silent filtration system. It measures 20” (50 cm) in length, 10” (25 cm) in width, and 12.5” (31.75 cm) in height.

The filter that it comes with is a Marina Slim S15 clip-on filter; and to further help you, it also offers you quick-change filter cartridges. Moreover, its rectangular shape helps in providing an excellent field for your Betta to swim freely.

The bright light helps pop the bright colors of your Betta, although it might be argued that the intensity of the light could have been a bit lower.

What We Like
  • Silent filtration system
  • Budget-friendly
  • Spacious
What We Don’t Like
  • The light might be too bright for the comfort of your Betta.
02

EcoQube C Aquarium

If you are looking for a chic and stylish home for your Betta, then EcoQube C Aquarium is what you need. This 2-gallon tank is equipped with an UV LED sterilizer and an integrated aquaponics filter that helps to clean the water by destroying the bacteria present in it and by putting an end to unnecessary algae bloom.

Besides, it also comes with a glass cover, a mountain stone, sand decoration, basil seeds, and a wireless remote control with which you can change the colors of the light and control the lighting effects.

After three weeks of purchase, the basil seeds sprout and grow to act as a natural filter that also helps in absorbing the waste materials in the tank.

Now, we understand the LED lights are not of the best quality available in the market, but considering its other features, this issue can be overlooked.

What We Like
  • Visually appealing
  • Integrated Aquaponics filtration system
  • Low maintenance
  • Includes substrate
  • Comes with an ornamental rock that acts as a hiding spot
What We Don’t Like
  • Expensive
  • Weak LED Light
03

Back to the Roots Water Garden Fish Tank

Described by its manufacturers as “not your typical Betta fish bowl”, the Back to the Roots Water Garden Fish Tank is a 3-gallon aquaponic tank, which is a closed-loop ecosystem in itself.

Combining both the functionalities of aquaculture and hydroponics (the process of growing plants in gravel, sand, or liquid instead of soil), this tank is designed in a manner that benefits both the plant and the Betta, creating a symbiotic relationship amongst them. The fish wastes help fertilize the plant that is located on top of the tank, and in return, the plant cleans and filters the water for them. In addition, it never hurts to have an herb plant at the top of your aquarium.

Equipped with organic seeds, natural fertilizer, gravel, stones, a submersible water pump, and fish food, this is a great buy for you. However, you do need a water heater for this tank since Bettas need warm water with a temperature of 76-82° F (24-27° C), and you might face some problem in installing a heater since its design doesn’t support most types of heaters.

What We Like
  • Self-sustained herb garden
  • Aquaponics
  • Symbiotic relationship between the fish and the plant
What We Don’t Like
  • Doesn’t support all types of water heaters.
