  • – Plug the filter and the pump
  • – Slide the lights into the slot
  • – Fill it with water


This is the perfect Betta fish size (five-gallon) with smaller dimensions than the Fluval Edge, making it ideal to fit in any room. It is also very light, making it easy for transportation or moving it to another room.


As we know, light is essential for the fish, and Fluval Spec V has excellent light features with 7,000 K LED high-output to highlight your bright Betta fish even more.

It also comes with a top-class 3-stage filter that works as a “water conditioner” and always keeping a healthy environment for your fish. It is a high-quality tank that is easy to use, even though sometimes the LED light might get into the way of feeding and cleaning.

One of the issues with this tank is the heater, which is not included in the box. This is not that big of an issue, but you’ll face the trouble of putting a new one just because there is no reasonable place to put it.

What We Liked

  • ​Affordable price
  • ​High-Quality Build
  • ​Quiet Pump
  • ​Good Looking

What We Didn’t Like

  • The Pump can cause a strong current that must be adjusted manually
  • ​Slightly Difficult Access to the Fish
  • ​No Heater


This tank comes with great features, which makes it one of the best betta tanks out there. The biggest drawback, though, is the heater position that will compromise the looks of the tank with the cables hanging out of it.

2. Aqueon Aquarium Fish Tank Starter Kit


Even though it is this fish tank is called a starter kit, it is a slightly bigger fish tank than the previous ones. People usually go for smaller fish tanks and then upgrade to a bigger one once they feel ready to take care of the fish properly. Aqueon Fish Tank comes in two options 10 or 20 gallons made from glass.


It has a great energy-saving LED lighting feature that is beneath the low-profile hood on the top. This means that the fish will get the necessary light illuminating the entire 10 or 20-gallon thanks while still consuming a low amount of energy.

Aqueon Quiet Flow LED Pro Power Filter gets the job done incredibly well, keeping the environment safe for the fish throughout its five-stage filtration process. It will also alert you when it is time to change the cartridge which is a relief. The filter is very quiet and best for people with sensitive ears.

Aqueon Aquarium Fishtank also comes with a heater that keeps the water at optimal temperature for your Betta fish as well as a thermometer to check it and net to remove any unnecessary things in your tank.

  • ​LED Lights are not High-quality
  • ​The Lid Does Not Have a Hinge


This is one of the best starter betta fish tanks and provides great features. It is for beginners who want an easy setup and keep only tropical fish like Betta. The only issue is the built quality that some people report a malfunction.

3. Hagen HG Fluval Flex Aquarium 57L, 15gal – Best Large Betta Fish Tank


This is a 15-gallon tank, and it is incredibly spacious which means there is room for plenty of decorations that go along with Betta fish. It has an interesting design with its curved front glass giving you a better view of your fish.


Unfortunately, this is not a 360-degree fish tank, and the backside is covered by the 3-stage filtration system. This means that there is plenty of room for all the elements like the heater and filtration system hidden out of sight behind the blacked-out the back wall.

Hagen HG Fluval Flex comes with 7500K LED, which is perfect for growing live plants as well as a remote control for the light. The remote will let you change different colors or turn it off or on. This is one of the most spacious aquariums on the market and the best size for Betta fish.

  • ​Very Quiet Filter
  • ​Easy Maintenance

What We Didn’t Like

  • ​No Heater Included
  • ​Hood Feels Cheaply Build


Hagen HG Fluval Flex is the right way to go if you want style over practicality. It will be the perfect highlight for the room, but the plastic feels cheaply built, and the filter sometimes does not get the job done due to the hiding layer in the back.

4. Tetra Crescent Acrylic Aquarium Kit – Best Budget/Cheap Betta Fish Tank


This is one of the best 5 gallon Betta fish tanks on the market. It is the ideal beginner’s fish tank that comes with a filter as well as a filter medium, which makes the job much easier. Even though it is made out of acrylic, it has high gloss finish making it very good looking.


Tetra Crescent also has 12 LED lights that are hidden in the backdrop providing the necessary light for the fish without compromising the looks.

The medium filter will absorb any unwanted odors from the tank, which is great.

However, there are a few drawbacks to this tank. The first one is the added filter, which is a bit large for this size aquarium. It will use up space in it making the fish go into the area of the water flow, which tires them out or stress them.

What We Liked

  • ​Beginner-Friendly
  • ​Powerful Filter
  • ​Don’t use a lot of space
  • ​Quiet
  • ​Affordable

What We Didn’t Like

  • ​Large Filter For This Size Aquarium

5. Marineland Contour Glass Aquarium Kit – Best Small Betta Fish Tank


When we talk about high-quality fish tanks, MarineLand Contour Glass is a contender. One of the first things you’ll notice on this aquarium is the light rail above the tank. It is a great design feature as well as provides the necessary light for the fish, which can be adjusted from white to moonlight blue highlighting all the fish you have.

There are two options available, 3 gallons or 5-gallon tank, which means that we are talking about a small tank that won’t be able to fit too many fish.


Marineland Contour Glass comes with its own three-step filtration system making sure your water is free of toxins all the time. It also comes with a filter pump and filter cartridge. The flow and detachable base are adjustable, which is perfect for creating a great environment for all kinds of fish.

  • ​Compact and Well Built
  • ​Very Quiet
  • ​Easy Set-up

What We Didn’t Like

6. Marineland 5 Gallon Portrait Glass LED Aquarium Kit


This is the perfect size aquarium for Betta fish, and it features all the things that you’ll ever need. Its unique design, similar to MarineLand Contour Glass aquarium, will highlight the beauty of your bright Betta fish.

It has the same LED moonlight (6 blue lights) that brings many benefits and daylight (9 white lights) feature as the previous one providing white or blue light that looks very beautiful. It is made from high-quality materials and thick strong glass, making it extremely durable. The curved corners will allow you to have better viewing angles of the aquarium and also makes it look elegant and expensive.


The filtration system is another great feature on this tank, which is located out of sight in the back behind a black panel, and it is ultra-quiet.

7. Aqueon 10 Gal Black Aquarium


Aqueon 10 Gal Black Aquarium comes at the more old-fashioned boxy shape and includes all the necessary equipment and supplies for beginners. It is made out of high-quality thick clear glass, making it very durable and long-lasting.

It comes with a separate black plastic hood with some pre-cut holes for positioning all necessary equipment. It is a very basic setup and very practical for maintaining. Three LED taillights to go under the hood to illuminate the entire tank.


It is filtered by Quit Flow 10 LED Pro filter, which is very quiet and uses filter cartridge to move water throughout the multi-step filtration system.

What We Liked

  • ​Bright LED Lights
  • ​Very Quiet Filter
  • ​You can Use Florescent Colors to Highlight Betta fish

What We Didn’t Like

  • ​Simple Design
  • ​Low Flow Rate, not enough to provide aeration to the entire tank
  • ​Not Practical- You have to remove lighting to access the tank


It is a basic fish tank that requires a bit more work to function normally. It does not have a very stylish design and removing and putting back the hood every time you feed the fish can struggle for some people. The low flow rate can also reduce the health of your fish so that you might consider a pump upgrade.

8. EcoQube C Aquarium


This is a more modern and innovative solution to aquariums. Most people do not buy aquariums just because of the work required to maintain them. Over time, algae will build-up, so you have to empty the tank, clean it and return everything to its place. However, things are not the same as the EcoQube C Aquarium.

It is a self-staining system built in the aquarium, which makes it maintain itself. It has a three-step cycle:

  1.   1. The waste of the fish contains ammonia which is broken down by bacteria into nitrates in the water;
  2.   2. The plant intakes the nitrates which are used for its growth, which filters the water;
  3.   3. After the plant absorbs all ammonia, the clean water is returned to the tank;

If you buy this aquarium, all you’ll need to do is Feed the fish and make sure you keep the constant water level of the aquarium. EcoQube C is a very innovative solution for aquariums, and it starts to get popular.


The EcoQube C comes with an Aquaponic filter, LED UV sterilizer, and LED light. All of these components work together, so you must keep them all running at all times. The UV sterilizer is used for removing any excess bacteria from overfeeding while the filter is used as a filter for the water from between the plant and the tank. The normal LED light is used to enhance plant growth, so every component has its purpose.

What We Liked

  • ​Modern Design
  • ​Aquaponic Filtration
  • ​Easy Maintenance
  • ​You can have your own Eco System

What We Didn’t Like

  • ​A bit expensive
  • ​Only One Size Available


Even though it is a revolutionary aquarium, it has a very basic setup following a few steps that are well described. It is a very small fish tank that holds about 1.5 gallons in volume, and it is built for only 1-2 fish.

9. Fluval Edge Aquarium with LED Light

Keeping in mind that fish tanks have kept the original shape throughout the years and we’ve seen only small changes design-wise, the story is the same with the Fluval Edge Aquarium with LED light. It has a sharp edge boxy design, which looks very good even though it has already been seen. It is a modern fish tank that becomes the center of attention wherever you put it in your room.


The LED light that is included in the Fluval Edge improves the design, and it is a great alternative to a reading or tabletop light. This aquarium sits on a stand that is also a great design feature making the fish tank like it is floating in the air.


Despite the LED light, the Fluval Edge comes with a 3-step filter which is hidden in the pedestal so that it does not compromise the design. This 3-step filtering process includes biological, mechanical and chemical filtering so you can be assured that you have the perfect environment for the fish. It also contains a pump that circulates water through the filter, and it is very quiet, so you don’t have to worry about frustrating noise.

What We Liked

  • ​Good Value for Money
  • ​Great Light
  • ​Beautiful Design
  • ​Great Filter

What We Didn’t Like

  • It is a bit difficult to clean


Fluval Edge is a beautiful aquarium that will highlight any position in the room as well as comes with decent features for keeping a healthy environment for the fish.

10. Back to the Roots Water Garden Self-Cleaning Fish Tank – 2 in 1 Aquarium & Plant Pot


As we mentioned earlier, these new innovative eco self-cleaning aquariums are getting popular at this moment. Back to the Roots works similarly to the previous fish tank EcoQube but it uses less equipment and simpler process.

Basically, this is a fish tank that has its own garden on the top and an underwater pump that channels the water to the plants which filter it. It is also a small fish tank that is perfect for your desk, and you won’t have to worry about cleaning it ever again.


However, every fish tank has its pros and cons. Back to the Roots Water Garden is a very good natural filter that uses plants that absorb the ammonia and creating a closed-loop. It is also a perfect decoration for your desk, having plants and fish that swim beneath it.  Just because the pump is underwater, there is practically no noise.

It is not all automatic processes, after all. The fish tank will eliminate debris and fish droppings throughout the tube in the middle, but the cleaning process will only begin when the weight of the debris is heavier than the water surrounding it. This means that harmful floating debris and algae manually.

What We Liked

  • ​The idea for producing your own food
  • ​No Noise
  • ​Easy Maintenance

What We Didn’t Like

  • ​Non-full Self-cleaning fish tank
  • ​Fish limitation due to small size


This is a small fish tank that is limited to only a small kind of fish. It has its limitations that are high prices to pay for a non-full self-cleaning fish tank.

Buying Guide

To get the perfect aquarium for your Betta fish, you need to know what to look for. There are different variables to consider if you want to create a healthy environment for your fish, such as:

Tank Size

Even though Betta fish are sold in cups at pet stores, which is fine for a short period, they do require adequate space to swim. Your general rule should be the bigger the tank, the better, especially if you are planning to have multiple fish. They will have healthier live in the larger fish tanks as well as enjoy a higher water quality. The minimal size should be 3 gallons, but the best choice is to go for 5 gallons or more.

How much elements you put inside (decoration)

Using decoration in your aquarium will not be a problem for your Betta fish if it is placed correctly. Sometimes decoration can get in the way of the water flow stressing the fish. You should be careful not to use too much decoration that will compromise the health of your fish.

Water heating, testing, and filtration

Keeping constant temperature is very important for creating a healthy environment for the fish. It is best if you add a thermometer in the tank and monitor the temperature so you can notice heater malfunctioning before it kills the fish. The best temperature to keep your Betta fish tank is between 77 and 86 degrees Fahrenheit.

LED Lighting

Lighting is also crucial for keeping your fish environment safe. Especially if you have live plants, that need to grow. Most of the fish tanks mentioned above have decent LED lighting that is perfect for illuminating the entire tank.

You should always pay more to get a higher-quality tank just so you can avoid leaks, cracks, and all kinds of other product malfunctions that could stress the fish and possibly kill them.


There are different style aquariums on the market, and all of them provide similar features. Choosing the best style depends on your specific taste. However, it is best to avoid bowls, bottles, or vases, just because Betta fish need the space to swim and filtered water providing a clean environment.

Betta Fish Behavior

It is important that you understand the fish behavior before you make you choose the tank you want to buy. Betta fish are housed in a solitary environment due to their aggressive nature when confronted with other fish. They seem to be jealous fish and attack male fish that have a more beautiful appearance to them.

These fish are commonly known to have male to male aggression, but there are many incidents that happened male on female aggression. This means that it is not wise to keep male and female Betta fish in the same tank. To avoid unwanted things, it is better to keep them separate except when mating.
