5 Best Betta Fish Tanks

Whether you’re a beginner when it comes to keeping an aquarium, or an experienced tank owner, you’ll already understand how fussy the beautiful betta fish can be. Of course, these stunning species are known for their vibrancy and stunning color, but they take work to look after.

One of the first things you’ll be thinking about is how you’re going to keep them. They’ll need a tank that’s large enough, especially if you’re thinking of introducing other fish. On the other hand, if you plan on keeping them alone (which is mostly recommended), it’s worth seeking out the perfect tank to keep your bettas happy.

Today, we’re going to give you everything you need to help you make this all-important decision. We’ve searched far and wide to seek out the very best betta fish tanks out there and explored each one in detail to clarify our choice.

So, let’s jump straight into it!

MarineLand Portrait Glass LED Aquarium Kit

MarineLand Portrait Glass LED Aquarium Kit

To start off our list, we’ve chosen the truly magnificent MarineLand Portrait Aquarium tank. We love this tank due to the larger size and portrait design which optimizes the amount of viewing space you of the inside of the tank.

This is ideal for admiring your betta fish, all while giving them more than enough room to explore and thrive. This, of course, means your betta will be happy, helping them live longer and healthily! The viewing space is even complimented by a curved front which again adds to your viewing pleasure.

Since this is an upright tank, you also get the ability to grow taller plants, which makes this even better for betta fish. Betta fish love to explore and hide and can be extremely fussy when it comes to territory and privacy. Luckily, having these tall plants gives them all the coverage they could ever need.

While this is on the smaller side, measuring in at 5-gallons, that’s perfect for a betta fish. As one of the more affordable tanks on our list, we know you’ll love the fact it comes with an integrated lighting system, complete with both white and blue LED lights which can help to create various kinds of lighting styles.

The light is also hinged, so you can position it easily wherever you want it. With a sliding glass top that allows you to easily access the tank for cleaning it, or for feeding your bettas, this could be everything you could ever need.

  • Sliding glass canopy for easy access to the tank
  • Portrait design allowing you to grow tall plants
  • Large viewing area amplified by the curved front
  • A built-in lighting system
  • Fixed lights with no room for a custom lighting rig
  • Lights are a lot brighter than you may intend

Fluval Spec V Aquarium Kit (5-Gallon)

Fluval Spec V Aquarium Kit (5-Gallon)

While a lot of fish tanks go out of their way to stand out from the crowd in terms of design and functionality, the Spec V is a great tank since it sticks to the basics of what you want a tank to be, and then makes sure it excels in these areas.

The shape of this tank is a standard rectangle, and measuring in at 5-gallons, this is ideal for most kinds of work surface, worktop, or even for positioning on a desk. This is backed by the lightweight design of being around the 10-pound mark.

What we really like about this tank is the fact it’s designed to be a complete starter kit. It comes with everything you need, including a built-in filter and purification area, which is hidden away in its own compartment, and a powerful 37 LED lighting system built into the top.

However, it’s worth noting there are many reports that these don’t last after six months, despite working really well.

Nevertheless, the setup does come with bio rings, a foam block and activated carbon for an effective three-stage filtration process, meaning you just need to add water and your bettas and that’s practically everything you need to do!

Despite the affordable price tag, this aquarium tank is really well made, and you can tell it’s built to last. With a large viewing area for admiring your bettas, more than enough room for your own substrate and your own plants, this is a complete experience that’s ready to go when you are!

  • A complete starter kit with everything you need to run an aquarium
  • Simple and versatile size, weight and design suitable for anywhere
  • A three-stage filtration and purification system
  • Includes materials you need to use the filtration system effectively
  • LED lights are not built to last
  • Smaller size than your typical aquarium tank

Tetra Crescent Acrylic Aquarium Kit

Tetra Crescent Acrylic Aquarium Kit

The Tetra Crescent Acrylic Aquarium Kit is another complete setup that comes with everything you need to get started with your bettas. This makes it perfect for beginners who are still in the learning process of aquarium keeping.

The design of this particular tank is simple, yet modern, and should be suitable for positioning anywhere in your home or office. There’s a wide area for viewing your bettas inside, including from the front and the sides. There are even cutaways in the lid, so you can easily access the inside of the tank.

As you would expect from an aquarium kit, the tank comes with a pump and filter setup that mechanically pulls water through the tank, through the filter cartridge and back into the tank, ensuring all dirt, grime and debris are filtered out along the way. This means you won’t have to clean your tank as regularly!

That’s pretty much all there is to this tank! It’s simple and effective and gets the job done with everything you need. If you’re an experienced tank owner, you might be looking for something a little more versatile, but if you’re looking for something basic that has everything you need straight out of the box, this is exactly what you’re looking for!

  • Comes with a filter and pump system
  • The wide viewing area for watching your betta fish
  • 16 powerful LED lights built into the tank
  • Cutaways for accessing the inside of the tank easily
  • Too basic for experienced tank owners looking for flexibility
  • Cutaways are poorly positioned for attaching cables and wires for tank equipment

The second Fluval tank to enter our list, this time the more affordable earlier version than the Spec V we’ve listed above. If you’re looking for many of the same features for a more affordable price tag, and some slightly more interesting design features, this could be what you’re looking for.

What you’ll love about this tank is the fact it measures in at 2.6-gallons, which is a little smaller than the other tanks on this list, but it’s still perfect for a betta fish and is perfect for people who don’t have much space for a larger tank.

You’ll have full visibility of your aquascape thanks to the three sides of the crystal-clear etched glass, while the back of the tank is a fully-functional 3-stage filter and purification system, much like the Spec V’s. This filter system comes with the foam, carbon and bio rings needed to get the tank running properly straight out of the box.

Included with this setup, you’ll find the clear lid with a cutaway, and an accompanying hang-over light integrated with 31 powerful and effective LED lights. All in all, this is a great starter kit for tank owners, or those looking for a dedicated betta tank your fish are going to love.

  • The built-in three-stage filtration system
  • Overhead lighting rig with 31 LED lights
