Looking for a Best Betta Fish Tank? You came to the right place! Betta fish are amazingly beautiful freshwater fish. Contrary to what you see in many chain pet stores, they are not best served in a tiny fish bowl. They need their own space to thrive. With the right aquarium, you can actually build a very affordable, small, and thriving environment for your Betta Fish.

What Is The Best Tank For A Betta Fish (Our Criteria)

I searched and reviewed a ton of aquariums for your Betta Fish. There are hundreds of fish tanks available to purchase online. How did we decide what was best? It came down to the following criteria.

Aquarium Size

Though my research and experience in fish keeping (over 25 years and counting), the best aquarium size for a Betta is a 5 gallon tank. Anything smaller will be too little space and detrimental for the long-term health of your Betta. Anything larger is too much space for a single Betta. Our focus on this review is ideal aquariums for a single Betta. An aquarium kit will also be preferred.

Filtration

I want a complete aquarium kit. Ideally one that comes with a filter unit built in. This makes maintenance easy to do.

Lighting

Ideally, I can find an aquarium with light that is suitable for beginner aquarium plants. Having plants in our aquarium will make things not only more comfortable for our Betta, but also healthier as plants will filter our nutrients in our water. These days led lighting is the way to go. If the light is part of a lid that’s a bonus for me.

Aesthetics

I want our Betta tank to look sharp. I don’t want equipment to be showing everywhere in the tank. I want this aquarium to look nice on a desktop, cabinet, or counter-top. I would prefer a lid to avoid evaporation issues.

Price

I don’t want this Betta tank to break your bank. It must have a good price, but at the same time, it needs to be value priced. If it’s cheap and offers me junky equipment, I’m not putting it on this list!

Finding The Best Betta Fish Tank

So now the moment you have been waiting for! Below is the list of the best Betta fish tanks on the market today. I put the preferred choices at the top for ease of selection for you.

In a hurry? I recommend the Fluval Spec V!

The Best Betta Fish Tank – Top 7 Reviewed (2020)

1. Fluval Spec V – The Best Betta Fish Tank Today

Editor's Choice!
Fluval Spec V

The Best Betta Fish Tank

Best filtration, best light, perfect size and with everything you need to get started. It was made for Bettas!

Buy On Chewy Buy on Amazon

Let’s start off the list with the very best of the bunch. The Fluval Spec V has everything you need. Let’s start off with the size of the aquarium. It is an ideal 5 gallon aquarium tank kit and is designed horizontally. Horizontal dimensions are better for fish like Betta because it give them more space to swim around side by side. The peninsula style with aluminum trim design give you a full view of the tank on 3 sizes. This makes it perfect to use on a counter top or cabinet as the plugs and filtration are hidden from view.

The filtration system is top notch on the Fluval Spec V aquarium kit. It comes with complete 3 stage filtration using foam as mechanical, carbon for chemical, and ceramic biomax media for biological. The filter components come out easily with a basket lifter. With the large filter chambers, you heat the tankdsss water temperature without seeing the heater.

The light is built for freshwater planted tanks. It led light has enough output for many beginner freshwater plants. The newest generation led lighting on the Fluval Spec Vs are 20% brighter than the previous. Your betta will look noticeably more colorful and vibrant under these lights.

The best comes with a price. The Spec V aquarium kit is one of the most expensive aquariums on this list. You get what you pay for with this aquarium and more. The light itself in my mind is cheaper in the long run than purchasing a similar output separate. The pump is also powerful for a Betta fish. You will want to dampen the output with a sponge on the outlet. This is a beautiful looking tank that will give our Betta the size and space it needs. Well deserving of the Editor’s choice badge.

Pros & Cons

Pros
  • Best filtration unit
  • Best LED light
  • Looks amazing
Cons
  • Powerful pump
  • Expensive

2. Marina Aquarium Kit – The Best Value in Betta Fish Tanks

Marina Aquarium Kit

Best Value

A more budget friendly alternative. Solid equipment and tank

Buy On Chewy Buy On Amazon

Marina is a value brand of Hagen. Hagen as you might already know is a high quality manufacturer of aquarium products in business since 1955. They are known for creating well priced start kit aquariums. This Marina aquarium kit from Hagen screams value. Like the Fluval Spec V, it has everything you need, but at a lower price.

Let’s start off with the package itself. It comes with not only a tank, light, and filter but other essentials to get you started. The aquarium kit comes with fish food, water conditioner, a fish net, thermometer, and biological supplements to get you started. All these together would cost you a fair amount of money. Given the price, I feel like Marina is practically giving this away.

The LED lighting that comes with this kit is powerful enough to house low light aquarium plants. The LED light fits within the canopy giving this aquarium a clean look.The lid is fully enclosed preventing evaporation issues.

What’s there not to like? The biggest thing is the power filter. While it comes with a sponge that will actually protect your Betta fish from getting sucked in, it can be an eyesore in the tank. The motor of the filter is housed with the intake, which allows you to hold more media in the filter. In a small Betta tank like this, motor can be easily seen. Placing a heater can be a tough to do with this as there isn’t a spot to place one. You will need to place the heater within the tank.

Still, this 5 gallon tank is a incredible value and worthy of my best value tag.

Pros & Cons

Pros
  • Great value
  • Good LED light
  • Comes with other essentials
Cons
  • Powerful filter
  • Heater placement

3. LifeWithPets Divers – Best Budget Option For Multiple Bettas

LifeWithPets Tank Divider

A DIYer's option. Divide your aquarium and house multiple Bettas!

Buy On Amazon Click For Best Price

Small aquariums go on sale all the time at chain pet stores. When these sales happen, you can purchase a great 5 gallon or 10 gallon tank for a Betta fish. When you get these deals, you can build a custom DIY aquarium with multiple Bettas with these tank dividers from LifeWithPets.

I love these dividers. These are my go to when it comes to multiple Betta aquariums. They are well designed and study. Designed from PVC, these dividers will last a lifetime in your tank. Because this is a DIY aquarium kit, you are free to divide up your tank anyway you desire.

Life With Pets Dividers

The kit I linked to is for a 10 gallon tank kit, which will allow you to house 2 male betta comfortably. The picture above is using a 20 gallon long tank divider. This allows you to house 3 male Bettas!

Because of their holed designed, The male Bettas will see each other and display their male aggression. This results in fin flashing and other desirable behaviors that show off your Bettas’ fins and color while also keeping your males safe from each other. Your Bettas will get their space and will remain active with the other males around.

What’s not to like about these dividers? The dividers are designed for Aquaeon glass tanks only. Other glass tank brands will likely have too tight of a fit and could risk cracking. Because of the design, it is recommended you place a filter in each section. I feel the cost of multiple filters can be mitigated by utilizing sponge filters. Check out our Best Sponge Filter blog post for the best ones to buy.

Pros & Cons

Pros
  • Well designed
  • Cheap DIY
  • Houses multiple Betta
Cons
  • Only works with Aqueon
  • Requires more filtration

4. Marineland Contour Glass Aquarium – A Great Cheap Betta Tank

Marineland Contour Glass Kit

A budget all in one aquarium that is a great size for a Betta

Buy On Amazon Click For Best Price

The Marineland Contour Glass Aquarium kit is a great valued priced Betta tank. The price for what it comes with is amazing. Marineland is a well known manufacturer of aquariums so you can purchase their tanks with confidence that they will last a lifetime. This is similar to Marineland portrait aquarium kit, but this won out because I like the lighting system on this over the portrait aquarium.

The main attractive with this tank is it’s presentation. The rail mounted LED lights give this Betta tank an wonderful touch. It looks amazing with nothing in it in person sitting on a desktop. The LED lightning is powerful enough to work with low light plants like Java Fern. I like the blue LED lights for the moonlight look as well.

The filtration system on this 5 gallon tank is a 3 stage unit using Marineland’s famous Rite-Size cartridges. These cartridges have bother mechanical and chemical in the same package and are easy to remove for maintenance. The tank comes with a lid that is easy to move out of the way when feeding or cleaning.

Great package with a great price. My biggest gripe is that you cannot place the heater in the filtration chamber. It’s recommended that you do not according to Marineland. I want to hide my heater with an all in one chamber so this is a big disappointment for me. The curved glass can look odd at certain angles, but not a deal breaker. The main money gripe here is the Rite-Size cartridge. It doesn’t use foam, which is reusable. The cartridges get thrown away after the carbon is exhausted, which means you need to continue to buy replacements. Long-term, that will add to your cost.

Pros & Cons

Pros
  • Good price
  • Looks great
  • 3 stage filter
Cons
  • Heater placement
  • Rite-Size cartridges

5. Fluval Chi – Zen-like Aquarium In A Small Package

Fluval Chi Aquarium

A great looking aquarium. Accents well in the home. Great for desktops and a great size for a single Betta Fish

Buy On Amazon Click For Best Price

Are you looking for a jaw dropping aquarium? If so, the Fluval Chi is easily the best looking aquarium kit on this list. The Fluval Chi is elegantly designed and inspired by Feng Shui. It starts with it’s clean horizontal design and its water flow.

The water flow is made by a specially design filtration unit. This unit filters from the bottom of the unit then filters down with a fountain like stream down to your aquarium. This creates a therapeutic setting. It does an amazing job of creating calm and accenting counter tops and even has a centerpiece on a piece of furniture. The water flow is so calm that it requires no modification for to use as a Betta tank.

So why isn’t this aquarium at the top of the list? It sounds amazing so far. Well, the LED lightning is not that great. I would not even recommend low light aquarium plants with the LED light it comes with. The filtration system is built into the light, which means if either the light or filter fails you have to buy an entire unit. The price to replace the light/filter combo is nearly as much as the aquarium kit itself! The final con is the dimensions. Bettas prefer more horizontal space to swim around. You can mitigate horizontal dimensions with a mirror or a multiple betta divider, but for a single Betta fish I would prefer a long tank.

Pros & Cons

Pros
  • Best looking aquarium
  • Therapeutic
Cons
  • Failure risk
  • Tank dimensions

6. Hagen Fluval Flex – A Large Betta Fish Tank

Fluval Flex

A larger and more robust all in one aquarium. Excellent for a Betta and has plenty of room for aquascaping

Buy On Amazon Click For Best Price

The Hagen HG Fluval Flex Aquarium debuts on this list as the largest aquarium. Weighing in at 9 gallons in volume, this tank will provide plenty of swimming space for your prized Betta and maybe a couple of peaceful tank mates. The Fluval Flex uses the exact same filtration system as the Flex Spec V. This true 3 stage filtration unit is top notch and the all in one chambers are large enough to fit a heater in the return section. The aquarium has some really nice touches to it. It has a feeding opening that you can use to feed your Betta and the return comes with a multi-directional output so you are able to spread out the current. The aluminum trim on the cover is very appealing and fits flush on the aquarium.

The LED lighting on this aquarium kit has some interesting features to it. The LED lights have the ability to change colors so you can do various color blends to bring out the best coloration out of your Betta fish. This is great for a fish only tank, however if you are going to add plants to the tank I would recommend keeping the stock settings. LED is part of the lid that fully encloses the tank preventing evaporation issues.

Speaking of plants, this light can handle low light aquarium plants. This saves you on having to purchase a separate Planted Aquarium LED. The white version of this tank pictured above is actually excellent for aquascaping. Many freshwater aquascapes prefer a white or frost background to bring out the max coloration of your plants.

This is a great aquarium kit with a few flaws. The price is up there near the price of the Fluval Spec V, but the Spec V overall is a better package. The glass has been known to crack easily due to it’s curved design. I am also not a fan of the honeycomb design at the top of the tank. I know it’s done to hide the waterline, it just looks odd to me, especially if you go with plants.

Pros & Cons

Pros
  • Large size
  • Filter system
Cons
  • Expensive
  • Past faulty units

7. Aqua One Trio – Great Concept But Falls Short

Aqua One Betta Trio

A great concept tank that can house 3 bettas

Buy On Amazon Click For Best Price

The Aqua One Trio is a great concept. It is an all in one aquarium kit that is specifically designed to house multiple male Betta fish. This is what every Betta fish enthusiast wants. It also has a hefty filtration system to handle three full growth males. At 8.8 gallons, it has one of the largest volumes on this list. It comes with a glass lid that is easy to remove when feeding and maintenance.  It looks like the perfect Betta tank on paper.

So what’s the issue with this tank? Where does it fall short? It is a great concept and a dream design. It looks slick too. My biggest issue is the divider design. The divider holes are not designed that well. With the powerful pump equipped on this unit, it is possible for your Betta fish to get stuck on the divider flow holes. The dividers also do not allow for even flow, meaning the chamber where the return is will have a heavy stream of water over the others. As you may already know, Bettas need calm waters. I can see how the male betta housed near the return chamber would be stressed from the flow. The LED lighting is okay not great. The Fluval LED lighting is superior in my mind.

Great concept and potential for a betta tank that needs refinement in my mind.

Pros & Cons

Pros
  • Houses multiple bettas
  • Great concept
  • Large size
Cons
  • Divider design
  • Light

To summarize, the Fluval Spec V is the best fish tank for your betta that you can buy today. It really has it all. It has the perfect filtration unit. The dimensions of the tank are ideal. The LED lightning that comes out of the box works for beginner plants. The tank also looks amazing in person. I recommend the Fluval Spec V for anyone starting up a Betta fish tank.

The Marina is a great value choice for those who want to spend a bit less but still want good features in an aquarium kit. It is cheaper than the Spec V aquarium kit and the LED lighting will still support low light plants. The LifeWithPets dividers are a great money saving option for those who want to make an Betta tank with multiple males.

Additional Tips And Tricks For Your Betta Fish

Here are some additional tips and tricks for you to keep your Siamese Fighting Fish in the best shape possible

Betta Fish Selection

Purchase your Betta from a reliable vendor. Betta are readily available at all pet stores including chain stores. Make sure you purchase a quality Betta that is not sick. Look for obvious signs like damaged fins, white spots, cloudy eyes, and red sores. Always ask the place you buying your Betta fish from to feed it and observe it eating. If it is near other males, look for signs of aggression. A healthy male Betta should display aggression to other males.

Betta Fish Tank Maintenance

Change your water at least biweekly to start after your aquarium has cycled. Always observe your water quality parameters with a proper Aquarium Test Kit. Once you get in the habit of testing and see consistency in your numbers, you can water change according to your water quality parameters. If you have gravel clean it out with a gravel vacuum. Clean your filtration media once a month with your tank water.

Aquascaping With A Betta Tank

You can build a fantastic looking aquascape with a Betta Fish Tank. These are super easy to maintain and setup. All it requires is some Driftwood for Aquarium and some Beginner Freshwater Plants. You can look at those links for additional selections on driftwood and plants. Most of the LED lights that come with the aquariums on this list will support plants. I’ve already took care of the guesswork for you 😄.

I know likely are in a hurry to go get your aquarium, so here is this quick video from Regis Aquatics showing a natural aquascape style using a Betta Fish for inspiration. Enjoy!
