Best Betta Fish Tanks In 2021

The best Betta fish tank that we’ve found that we believe offers enough for everybody is the MarineLand Portrait Aquarium Kit. For those of you just getting started, it’s the ideal place to start and provides a perfect 5 gallon Betta tank to ensure they’re nice and comfortable in their new home with plenty of room to explore.

The white and blue LEDs mimic the ambiance of the ocean, while the hinged light and sliding glass canopy make it super easy to feed the fish and complete your weekly clean which will be made even easier with the advanced 3 stage filtration. For aesthetic purposes, there’s also a hidden pump that ensures a more authentic experience and has plenty of room for decoration of all kinds, from stones to sand to underwater vegetation. It makes it feel so real, even you might want to climb in and check it out yourself. It makes a perfect Christmas gift for any animal lover.

Light is essential in any Betta aquarium and this Fluval Spec V Aquarium Kit might provide that light like no other kit on the market. Boasting massive 37 LED lights that overhang the tank, your Betta is sure to be one happy fish. The five-gallon capacity ensures there’s also ample space for it to swim around, while also saving you a slight cleaning job – hey, at least it isn’t 10 gallons, are we right?

Furthermore, this Betta fish tank kit comes with 3 stage filtration, something which is essential to keeping it as healthy as it is happy and also has an adjustable nozzle output which better contributes to more efficient filtration. As for the design of the tank, it’s smart etched glass and has classy aluminum trim which the fish may not care about, but you might. A great housewarming gift for any home.

A product that’s indisputably top of the cool Betta tanks column, the Aqueon Betta Falls Kit provides 3 tanks in one through its multi-stage design that comes with adjustable water flow control and also has fill levels so you can keep up to date with its condition with ease.

You’d think that three levels would cause some noise, but you’d be wrong. The Quiet Flow power filtration means the whole process is almost (almost) silent but also extremely effective, and keeps the water clean and healthy. It’s not as large as we (or you) might like, but for smaller spaces, it’s a stylish option that might be too hard to resist. An amazing Christmas gift for dads and kids.

The biOrb Classic Aquarium comes with a long-lasting ambient light that perfectly sets the tone of the tank and eases your Betta fish into its new environment comfortably. It’s the only tank we’ve selected that offers a mighty 5-stage filtration and has a universal filter cartridge which will save hours of searching for the perfect replacement.

Also, unlike other tanks, it’s constructed using acrylic, which is stronger, lighter and clearer than glass and will certainly save any tears should it topple from its shelf. Available in either 4 or 16-gallon options, you’ve plenty of chance to start building something that your Betta will think is home, sweet, sweet home. Be sure to combine this with an aquarium filter from our list.

Working on a closed-loop ecosystem that is maintained by fish waste (we know, but stick with us), the Back to the Roots Regular Water Garden is a tranquil product that uses aquaponic systems to utilize self-cleaning (yay!) through the plants acting as filters and fish waste as a fertilizer.

For this reason – among others – it’s perfect for beginner fish owners, and in the package, you get everything you could need from a starter kit including sprout seeds, a submersible water pump, and gravel for a more genuine environment. BttR also encourages owners to send images of their tank in for the chance to win in a monthly giveaway, which might be enough to convince you, maybe.

Our final Betta fish aquarium comes in the form of this compact Tetra Crescent Aquarium Kit. it uses energy-efficient LED lighting systems to keep the tank illuminated while not wrecking your energy budget, and the ultra-activated carbon halts odors and water discoloration in its tracks, which is great for you and the fish.

The operations are also quiet, giving you the peace that you so desperately deserve, and its size makes it ideal for placing on the kitchen counter, in the dining room, or on your desk, and is sure to offer you hours of peace simply gazing into it from time to time. If that sounds like bliss, it probably is.

Betta fish (or Siamese Fighting Fish) need a five-gallon tank (minimum) if you want them to have a good life. They like to explore their surroundings and anything less than five gallons doesn’t give them the space to do so. This 20-gallon tank is four times that minimum requirement. It gives them the freedom to live like they would in the wild (kind of) making them happier, healthier pets. 

This Tetra Glass Aquarium is made in the USA and features scratch-resistant glass, so it can last a long time without aging. It has an LED hood that provides a natural daytime effect for the fish and making this fish tank look fantastic in the dark. Plus, it comes with an integrated Whisper Filter, one of the quietest filters on the market, and a Tetra Mini UL Heater. In short, it’s decked out with everything your fish need for a happy life. 

Why should your fish settle for living in run-down, substandard accommodation? You wouldn’t choose to live in a dilapidated studio apartment if you could live in a hillside mansion instead. The Tetra 55-Gallon Aquarium Kit is your fish’s dream house. With a whopping 55-gallon capacity, your betta has over 10x the minimum required space. That means they can spend their whole lives exploring the tank, forgetting it all, and then exploring it all over again. 

One of the things that really stood out about this tank is that it comes with everything you need to get started. As well as the tank, you get a bottle of EasyBalance Plus (to improve the water health in the tank), AquaSafe (to neutralize harmful chlorine, heavy metals, etc.), and Tetramin (to feed your fish. Plus, it comes with a six-inch fishnet, a 200W heater, a WPF 60 Filter, a digital thermometer, two plant multipacks, and a boxwood plant. 

If you really want betta in your tank, you need to have enough space and think carefully before you buy them – betta fish are definitely not starter pets. This tank – the Koller Products AQ15005 – is the smallest tank we’d recommend for betta fish. With a capacity of five gallons, they should have enough space to explore without going stir-crazy. Really, this is the most affordable and space-efficient way to have betta fish. 

One of the features we like most about the Koller Products AQ15005 is the multicolored LED system. Built into the lid, you can illuminate your fish in seven different colors – daylight white, blue, green, amber, aqua, purple, or red. We also like the fact that it has a powerful internal filter that gets through 45 gallons of water a day. 

If you’re serious about owning betta fish, you should make them the centerpiece of your living room. The Midwest Tropical Coffee Table Aquarium Tank is the perfect way to do just that. Sure, it’s not the most subtle of fish tanks but it puts your prized betta on view for everyone to see. If you’re proud of your fish, this is the tank for you. 

With a capacity of 28 gallons, it provides plenty of space for your betta fish to explore, so they can lead a happy, healthy life. It also has an octagonal shape, which encourages fish to explore different corners of the tank that you can fill up with all manner of aquarium miniatures and greenery. The only slight downside of this tank is that it doesn’t come with a heater or filter, so you’ll have to buy these separately and install them yourself. It’s designed as a freshwater tank but it’s easy enough to convert for betta fish. If you want to enjoy your beautiful fish as you relax on the sofa, this is the best tank for the job.
