Providing a decent home for the bettas in the world is key to their well-being and overall health.
Betta-friendly starter aquarium kits come in different shapes and forms that may seem attractive at first sight. However, despite its practical small size, the best 5-gallon Betta fish tank should definitely include the right side equipment and not just a glossy design.
Of course, so should a 10 gallon one or even a 20 gallon one and these are, in fact, an even better choice for the fish itself.
What’s the smallest aquarium you’re allowed to go for without hindering the fish’s health? The thing should also come with a built-in filter, proper lighting and if you’re lucky a heater. These are mandatory and I discuss them separately in detail. So what’s the best home fish tank for your new Betta fish and is there a suitable all-in-one kit?
Let’s get right to the point.
Though being small and often sold in jars bettas need their personal space and room for scouting.
Researchers have concluded that keeping these fish in small, unheated fish tanks result in less movement and higher mortality rates.
They are curious and sometimes antisocial little explorers.
Remember that heavily decorating an aquarium with plants, that also has a decent water capacity is pretty much essential for these little grumpy fish.

An A-to-Z guide to fish tanks and their role in the life of a Betta
I wish choosing the right tank was simple, but it’s not. For this reason, I’ve crafted a guide that explains in detail everything you need to know before making a purchase. Here’s what you should know before buying a fish tank for your betta:
1. Finding the best size and aquarium volume for a Betta fish
Fish stores sell bettas in small jars or bowls. This, however, is done for display purposes and is only fine for a very short period of time. A study found that reduced environment increases aggression and stress in fish. That being said, here’s the best tank size for a Betta fish:
The absolute minimum fish tank size acceptable for a healthy Betta fish is 3 gallons. Smaller aquariums than that will result in a shortened lifespan and a poor quality of life. A single Betta will best enjoy a 5 to 10-gallon fish tank but a larger one will also be appreciated.
In small fish tanks, water gets polluted very quickly which leads to an unstable environment.
Fluctuations in pH, raised ammonia or nitrites caused by decomposing waste, are all potentially lethal to fish.
A big fish tank is (counterintuitively) way easier to maintain and the water parameters are usually more stable. This is another reason I recommend that beginners get a large aquarium, especially if the Betta is their first-ever fish to adopt.
It should also be noted that in smaller fish tanks there’s less swimming space and therefore less room for exercise.
The dimensions of the tank will influence the Betta’s growth and the maximum size it can reach. Getting a bigger fish tank is always advisable.
I have a whole section where I sorted the aquariums reviewed in this article by their gallon capacity here.
2. Having a filter is actually necessary
Generally speaking, an aquarium filter does 3 things in a fish tank:
- It provides mechanical filtration. This means capturing debris and small free-floating particles that make the water visually unappealing, but could also clog a fish’s gill.
- It provides biological filtration. This means providing living space to beneficial bacteria, which convert toxic ammonia and nitrites to other harmless molecules.
- It aerates water by moving it. Stagnant, low-on-oxygen aquarium water leads to a stressful way of life for fish and is never recommended, unless explicitly suitable for the particular species.
That being said, here’s if a Betta needs a filter in its aquarium:
Bettas do require and will appreciate water filters as they are not as hardy as fish stores advertise them to be. These fish produce enough waste for unfiltered water to become toxic, especially in smaller fish tanks. A good aquarium filter will also oxygenate the water, which promotes energy levels and more active swimming. Therefore the best fish tank for a Betta should include a filter.
I made sure that the aquariums listed below all include a filter for your peace of mind.
Note that Bettas have an organ called labyrinth, which allows them to breathe atmospheric air.
This is a survival mechanism because they are native to rice paddies.
3. Water current should not be too strong
If you’re going to buy a separate filter for your Betta’s fish tank anyway, don’t get one with a strong current.
Bettas have enormous fins and the current may exhaust them easily.
Naturally, this can make swimming difficult and unpleasant for them.
If you already have an old filter you’d want to put to use, you can install a cylinder intake sponge to decrease water turbulence.
Getting a self-cleaning tank with an aquaponics system on top solves the current issues, while the fish tank remains free of dangerous chemical build-ups because the plants will use them up as food.
4. Lighting and what it does for the setup
Here’s why your Betta fish needs to live a well-lit water tank:
Bettas have their own sleeping cycle and a lighting schedule will help with normalizing it. Another reason to have lights in your fish tank is growing aquatic plants.
Both are important factors in providing a healthy environment for a Betta fish.
However, aquatic plants deserve their own separate section, because…
5. Decorating with aquatic plants is essential for reducing stress levels and increasing activity
Stress from poor fish tank decoration can leave your buddy lethargic.
A common expression of that is laying on the bottom while being turned on the side.
Here’s why your Betta needs plants in its fish tank:
Bettas are curious fish. The more decoration and aquatic plants their aquarium has, the more active they will be. They like to swim around, exploring stuff in the aquarium. Aquatic plants greatly reduce the stress levels of this fish so it’s best to go for a planted tank. Less stress results in longer life and more exciting fish life in general.
I personally hate it when I see almost empty fish tanks with only 2 stones and a Betta in them.
Another thing that’s worth mentioning is that bettas will absolutely appreciate having personal space.
This resembles their natural habitat.
Having dense vegetation and hideouts in the aquarium provides the Betta with places to rest, should the attention from owners or tank mates becomes overwhelming.
6. The heater maintains a tropical environment
Bettas are tropical fish and require a constant water temperature of 75° to 82° F (24° to 28° C).
But does that mean that they require a separate heating unit?
To find out if your Betta needs an aquarium heater, consider this:
A betta will need an aquarium heater unless the fish tank is situated in a year-round warm location. If you live in a geolocation where there’s cold winter and a constant water temperature of 75° to 82° Fahrenheit (24° to 28° Celcius) can’t be maintained then supplying your Betta’s fish tank with a heater is vital. Set the heater to the desired temperature and don’t allow for fluctuations.
Water temperature affects the behavior of Bettas.
Unfortunately, the aquarium kits reviewed below rarely include a heater in the pack.
What is the best and most stylish container for a Betta fish?
The best and most desirable Betta tank needs to have enough room for exploring interesting decorations, and a bunch of solid functional side equipment. The right starter-friendly setup will ensure a healthy, calm and long-living fish. The reviews below include models that are all suitable for an entry-level fishkeeper. Here are the 10 best aquarium tanks for a Betta fish:
1. Tetra LED Cube Kit with Pedestal Base – Smaller Budget Option
This starter kit is among the best budget options for those who are super eager to start their small Betta tank.
The value for the price is just outstanding though it’s nowhere near what more expensive aquariums offer.
If you end up buying this fish tank kit, know that you’ll have to invest in a heater, if it gets cold in the winter where you live.
You can read my section above about water temperature.
I did some additional research and many users recommend getting the Hydor 7.5w heater.
I’m not particularly happy with that one, so I’ll let you know what works best for my tropical fish in smaller tanks – Tetra TH Submersible heater.
Anyway, aside from that, this fish tank has its own filter that does the job at first, but be prepared to upgrade to a better one later on.
The filter’s a bit too strong for the massive fins of a Betta, so make sure that you block the intake with the decor of some kind.
In fact, this is the reason I would only recommend getting this product if you’re in a hurry to start your fishkeeping journey while being tight on the budget.
For the best performance and a happy Betta you should probably upgrade this fish tank with a more gentle filter in the future.
Speaking of side equipment, the kit also comes with LED lighting in the pack.
Frankly, the LED is weak by most standards and you won’t be able to grow many live plants with it.
Good recommendations here would be java moss, Masimo moss balls, and java fern as these are some super non-demanding species.
Anyway,I like the look of this aquarium because it’s not your conventional 3-gallon one. It has a stylish shape of a cube and despite its small size, it can be a good introduction to the hobby for keeping a single small fish.
Don’t forget to cover the feeding hole on top, by the way. Bettas are well-known jumpers.
I’d buy this small aquarium if I were really tight on budget but were prepared to upgrade a few parts in the future. In fact, it would probably be best to upgrade to a 5-gallon one when your single small Betta outgrows this tank.
Still, I definitely consider the Tetra Cube Kit to be in the top 10 ones.
It’s an ideal temporary option for one young Betta fish.
I’d also definitely stuff the thing with lots of plants that require low lighting and a small piece of driftwood because the overall design allows for a really cool display planted fish tank.Advantages:
- Super duper budget friendly
- It comes with almost everything
- Made from acrylic for even better aesthetics
- The design stands out
- Does not include a heater (get this one if it gets cold in the winter where you live)
- The built-in filter is not that durable (upgrade to this inexpensive one if anything)
- Built-in LEDs can grow a limited number of plant species (Though the type of plants are limited you can still have a heavily planted nano fish tank)
2. MarineLand Portrait Glass Aquarium Kit – Pay Less for More
To be honest, the Marineland Portrait Glass Aquarium is one of my personal favorites on this list.
I just can’t comprehend how the manufacturers managed to provide so much value for the money.
One of the best things about this aquarium kit for Betta fish is that it comes with a 3-stage filter, that’s actually hidden at the back.
The filter is strong and silent, which is a rare combination that makes up for an ideal addition to any living room.
It also has an adjustable flow, which is just gold because it minify the water’s turbulence sparing large-finned fish the extra effort to move around.
The last two traits alone classify the MarineLand Portrait Glass as the second-best Betta fish tank with an included filter as side equipment.
Next entry will reveal my personal winner in this category, however, this one here shines with a more stylish look.
Anyway, back to the filter as I feel mentioning that I’ve found the lowest possible flow rate setting is still a bit strong for a Betta.
Just put a sponge on the intake to reduce it further and you’ll be good to go.
The lights that are included in the kit will grow low-light plants such as Java Fern and Anubias without issues, so don’t forget to add those for a more lively decoration.
The vertical design of the tank is beautiful and provides enough swimming space for an active Betta fish.
I don’t see many cons, given the price, and, perhaps, one that stands out is that the filter itself is somewhat difficult to clean.
The back-area that hides the filtration system collects debris, which can prolong the establishment of the nitrogen cycle if you’re not diligent with the cleaning.
It’s just essential that you remove those timely, and it’s not that easy, really.
Aside from that, the tank kit is perfect for the money and pretty suitable for a new Betta owner.
I recommend buying this product if you’ll appreciate having one of the best and most stylish-looking fish tanks for your Betta, that’s also very silent.
All of this without really breaking the bank.
Just be sure you’re willing to stay on top of maintenance.
Note that some users report that their darkly-colored bettas can’t really stand out from the black background.
If yours is darkly colored (read near-black) – skip this entry as it will somewhat defeat the purpose of the whole thing.Advantages:
- The built-in filter is silent
- The filter is hidden, so it doesn’t hinder aesthetics
- Built-in LEDs can grow low-light plants
- Definitely inexpensive, for all that it provides
- Vertical design encourages exploring behavior and more movement
- Back chamber collects gunk and needs to be cleaned thoroughly during maintenance
- No heater in the kit (Amazon has a deal for that)
3. Marina LED Aquarium Kit – Best Side Equipment for the Money
As the title goes you’ll get the best side equipment with this fish tank kit.
The Marina Aquarium kit comes in 3 sizes – 5, 10 and 20 gallons.
The price difference between them is so small that you should really get the 20 gallons one if your home or office space allows it.
However, if your budget or available space are somewhat limited, you can still buy the smallest version as it is probably the best 5-gallon choice for a Betta tank in regards to the provided value.
Aside from being super affordable, this fish tank kit comes with a filter from an established brand.
Marina is really popular in the hobby with their standalone HOB filters (Hang-on-Back) so you could expect that from them.
The filter does a fantastic job of keeping the tank clean while operating silently.
It has an adjustable flow, which is a major advantage for all-in-one fish tanks.
Another positive here would be that the built-in lights are also outstanding for the price.
In fact, I think they’re the best ones that you can get as side equipment of an all-in-one aquarium for Betta fish.
They will definitely grow a majority of low-light plants and even a few medium ones.
The LED light fixture also makes the colors of a Betta pop nicely.
You may find yourself seeing coloration that you never thought was there.
Anyway, the setup process is as beginner-friendly as it gets.
The only thing you’d want adding to this fish tank is a heater.
As a conclusion I’d buy this aquarium kit if I were new to fishkeeping and wanted to provide the best possible all-in-one setup for my Betta fish without breaking the bank.
The Marina aquarium is a safe ground for learning the hobby without endangering the wellbeing of a fish.
I give it a score of 10/10 and I definitely recommend!Advantages:
- Best side equipment you will get in an aquarium kit
- The included filter keeps the water sparkling clean
- The filter is also virtually silent upon proper maintenance
- The built-in LED lighting can grow a huge variety of low-light plants
- Does not limit you to hardy live plants only
- Comes in 3 different sizes (5, 10, 20 gallons)
- Fantastic pricing for what you get
- Classic design
- Does not come with a heater
4. Hygger Horizon – The Show Off
The Hygger Horizon is a great display fish tank with a curved front glass and a 3D rockery background in which you could house no more than one Betta.
Though the tank is advertised as having a volume of 8 gallons, the background does take up space, leaving an effective swimming space of just about 6 gallons.
The realistic 3D background, however, is worth it, as it adds real depth to the whole aquarium look. It also covers less than 100% of the back wall, leaving some private space beneath it for your fish.
Combined with some densely planted aquatic plants, this little hideout works incredibly well for reducing stress in Bettas, giving them the occasional privacy they need to have.
Speaking of plants the built-in light is rather impressive and it comes with customization options that no other aquarium kit on this list includes. You can switch between 3 different color modes, and the full-white one actually grows a wide variety of plants with low-light requirements. And let’s not forget the built-in light timer.
Another plus is that you can also tune down the intensity of the fixture, which actually allows for more flexibility with the plants.
One of the best things about this Betta-friendly fish tank is that it comes with its own filter. The filter is rather durable and reliable for this price bracket, but the nice thing about it is that it also comes with some customization options. It has a water flow control knob which allows for adjusting the flow, which comes in handy when keeping those beautiful large-finned Bettas.
It’s not really intuitive on how to disassemble the filter when the time for changing the media comes, but it’s not hard either.
I honestly can’t say anything bad about this fish tank. The company that manufactures it is super responsive and they’re always eager to help and answer your questions. I really tried to find a valid bad experience with the Hygger Horizon, but instead, I found what clearly appears to be human error or faulty delivery. The product itself is solid.
Perhaps, the only thing that actually needs mentioning is that it’s an open-top design, so you’ll need a net of some sort to prevent your Betta from jumping out.
Buy the Hygger Horizon if you’d like to own a display Betta-friendly fish tank kit that’s easy to set up, has an impressive design and above-average quality of the side equipment.Advantages:
- Excellent exterior design
- Easy set up if you’re a total beginner
- 3D background that adds the sense of depth
- Quiet 2-stage filter that has adjustable flow
- LED lighting with 3 color modes and intensity control
- The light grows easy aquarium plants well
- Hideout under the 3D background where your Betta fish can rest (this is helpful for reducing stress)
- No heater in the pack (Hygger actually have a good solution of their own which you can check on Amazon here)
- No lid (though not all Bettas will attempt an escape, it’s good to have a safety net of some sort to prevent potential jumps)
5. biOrb FLOW Aquarium with Light – Compact & Beautiful
In my opinion, this fish tank has by far the coolest appearance and design from the ones listed here.
It comes in 2 sizes – 4 and 8 gallons, both suitable for a Betta fish.
It’s a little pricey, but I guess it goes without saying that it would be best if you get the larger one in case you can afford it.
It has its own filter, which tends to be a bit strong for a Betta, but you can simply clamp the tubing with paperclips to reduce the flow.
I think it would be best to point out that the filter is advertised as a 5 stage one and, in fact, will filtrate each gallon of water in your new Betta tank nicely. However, only one of those stages is set for biological filtration. For this reason, I recommend to step up your decor game. This way beneficial bacteria will have more surface area to colonize.
The LEDs of this tank kit are not the strongest out there but will allow for a couple of low-demanding live plants.
The cleaning is not that easy, but it’s not annoying either.
The only thing that this aquarium setup lacks is a heater.
Get a small aquarium heater as bettas are tropical fish.
The lid doesn’t have a hole for the cord of a heater, so you may need to modify it (drill a little hole, nothing more).
I’d buy this aquarium starter kit for my Betta fish if I wanted a gorgeous centerpiece for my room or a stylish addition for my overall neo interior design.
Nothing beats the design, and the fish tank has a sturdy build. The smaller version would be suitable for a single Betta with a couple of shrimp or snails.Advantages:
- Top-notch design (no, really, it is)
- Has a 5-stage filter and LED lights
- Setting it up is non-challenging
- Comes in 2 different sizes (4 and 8 gallons)
- The design limits you to only using biOrb equipment
- A bit pricey
- Needs a heater if you don’t live in a year-round warm climate
- Needs small one-time modifications to be fully equipped with gear
6. Penn Plax Curved Corner Glass Aquarium Kit – Affordable with Quality Filtration
This aquarium kit comes in 4 different sizes – 3.4, 5, 7.5 and 10-gallon tanks.
On top of that, all are pretty affordable for the value you get with each.
The bigger kit you buy – the better for your Betta, obviously.
The design is clean, nothing too special, however, it has a classy vibe to it.
Penn Plax is also a well-known brand when it comes to canister filters so I did expect that same quality with the internal one you get here.
Turns out it works great and without issues. To best describe it, I’d say that for the purpose of keeping a single Betta in this fish tank the filter has a very simple structure that does a wonderful job for the offered sizes.
It is really more than enough to provide a decent filtration, while being somewhat sturdy thanks to the simplicity in its build.
The cartridge has its own 2 chambers in which you can put custom filter media.
Anyway, you should probably know that the lighting is not that bright so it’s more of an addition for aesthetic appearance rather than a grow light for aquatic plants.
You also need to plug and unplug it every time, because there’s no on-off switch.
Therefore, I’d recommend that you stick to very low-light plants if you don’t decide on upgrading with a better fixture.
Another thing to consider as an upgrade for this setup is an aquarium heater, in case you live in a place with a chilly winter.
Anyway, the lid does not require modifications on your part when adding the heater as there’s enough space for the cord, which I think is great and rather rare with aquarium kits.
In my opinion this is an overall great classical-looking fish tank to have your Betta in.
Buy this aquarium kit if you enjoy clean unconventional design and do not really care about growing more difficult aquatic plants.
It’s a well-justified choice for a tighter budget.Advantages:
- Round-edge glass design that’s clean yet stands out
- Comes with an internal filter that works more than well
- Comes with lights
- On the cheap side
- The light will not grow many plants
- Needs a separate heater if you don’t live in a place with a warm climate
- The filter is somewhat noisy
7. Fluval Spec V Aquarium Kit – The Smart Choice
Aside from manufacturing some of the best canister filters, Fluval has stepped up their game in the nano fish tank field as well.
This small 5-gallon aquarium costs a bit more, but it’s really one of the best ones for a single Betta fish if the budget is not the limiting factor.
The setup process is straightforward and you won’t really bump into any obstacles even if this is your first time doing this.
What I really like about the fish tank is its shape though, and aesthetics is not the main factor here.
See, the longer shape allows for your Betta to actually swim around without feeling confined in the 5 gallons of water.
This way your little pet fish will have plenty to explore, especially if you load the Fluval Spec V with lots of live plants and decorations.
As every decent aquarium kit, this one comes with its own lighting and filter. Both of these work well for the space of 5 gallons and are also rather durable.
The filter and its pump motor are enclosed, which is a plus in a small fish tank kit like this one.
The water filter filtrates without hesitation and keeps the water clean while being silent, which makes the Fluval Spec V a good addition to a living room where you spend more time.
Still, you should keep the water level in check in order to avoid splashing sounds, unless you enjoy this (some do and actually prefer it this way).
Though the current is a bit stronger for a large-finned Betta you can just stick a cheap sponge in the intake and be done with it.
The 37 LEDs are strong enough to grow most low-light aquarium plants, which is great for reducing stress levels in your Betta fish.
The fixture has a “night mode” which looks good, but is somewhat bright and may disturb the fish’s sleeping cycle.
The overall build of the fish tank is sturdy and it will last you more than other, cheaper ones.
The only thing this aquarium kit lacks is a heater (as with most aquarium kits).
A con I would like to mention is that when you get your heater, you’d need to slightly modify the lid for the heater’s cord.
It does not have a hole for that and it doesn’t look good with a half-closed lid.
Be sure to get this fish tank kit if you’re okay with paying a bit more in return of product durability and increased life quality of your Betta.Advantages:
- More horizontal space that allows for bettas to explore, keeping them busy
- Great LED lights for most low-demand live plants
- The filter is functional, silent and not ugly looking
- Durable build
- Price (though higher, I think it matches the quality exceptionally well)
- Easy setup even if you’re a total beginner in this kind of stuff
- Needs a separate heater if it gets cold in the winter where you live
- The water level should be maintained to avoid “splashing” sounds if you’re not into this
- The lid does not allow for additional equipment with cords (you can drill a small hole, nothing complicated or hard)
- The aquarium’s built-in filter is a bit strong for a Betta fish and needs a small sponge to the intake
8. Fluval Edge – the Artsy Choice
The guys from Fluval always go the extra mile.
With their Fluval Edge Aquarium, you get a very nifty design that suits even the most exquisite homeowner.
Aside from that this fish tank kit also comes with a filter and a lighting fixture, but no heater.
The aquarium filter may run a bit loud before it loses all the air bubbles trapped inside.
You’ll need to wait that period off and eventually the noisiness will sort out itself.
You can speed that process up by tilting the filter from time to time.
It will eventually run smooth and quiet.
Anyway, the built-in LED lights are pretty impressive and allow for low to medium-demanding live aquatic plants to be grown.
Live plants in such a stylish tank look gorgeous and your Betta will definitely love them as well.
By stuffing some green inside this aquarium you will make for a scenic exterior view on top of providing an interesting and less stressful environment for the Betta fish.
Don’t forget to add driftwood as you’ll be missing out on aesthetics otherwise.
There’s also a moonlight option to the LEDs which I do not recommend using, because this way the glass reflects images from inside the fish tank.
This can stress your Betta as it may think that there’s an opponent in the tank, so it’s really best to avoid that.
The few downsides of the Fluval Edge that I could think of, are the noisy (at first) filter and the price, because this aquarium kit does not include a heater.
If you’re wondering if this is the right product for you I’d say that I would buy this fish tank for my Betta if my budget wasn’t a limiting factor and I was really into the stylish interior design of my room.Advantages:
- An absolute masterpiece in terms of design
- The filter keeps the water clean at all times
- The filter, lighting, and pump are hidden, not to interfere with the top-notch design
- The light will grow low & medium live aquarium plants
- Not a budget option
- The filter can be noisy at first (because of micro air bubbles, which will sort itself out with time)
- Moonlight option can stress a Betta (just don’t use it)
- Needs a heater
- Needs an oxygenator if you choose to keep the water level to the top (Betta fishes breathe atmospheric air and need to have some space above the water line to show up unless the water is artificially oxygenated)
9. Fluval Flex 57 Nano Glass Aquarium Kit – A Modern Design
The Fluval Flex 57 comes with just about anything a Betta fish would need, except, of course, a heater.
One of the best things about this aquarium is that it has a beautifully sleek design, though you won’t be able to see your fish clearly from every angle because of the shape of the container.
It’s advertised as a 15-gallon fish tank, but from what I’ve seen the usable living space for a fish would be just above 10 gallons.
That’s because the back hides the filter and pump and Fluval included that in their calculations for some reason.
Nevertheless, the side equipment works wonders and is reliable.
The included lighting fixture is pretty decent because it will grow a variety of low and medium-demanding plants for your Betta’s chill places.
The water filter is durable and keeps the fish tank clean, but it lacks the adjustable flow feature.
This could be an issue for Betta fish with massive fins unless you reduce the current with sponges in the intake and outlet (yes, both!).
If the current remains strong I recommend getting a separate, smaller aquarium pump that will go easy on your Betta. I looked around on Amazon and this one seems like one to do the trick.
The hidden chamber on the back of the Fluval Flex 57 provides space for extra equipment and the lid allows for extra cords to go in there, which is rare with stylishly designed aquarium kits.
I recommend buying this cool starter-pack fish tank for your Betta if you like its awesome design and your budget is not limiting you.
You may also enjoy this purchase if you want to take advantage of the decent LEDs and provide your Betta with some lush green aquarium plants, which is recommended anyway.
All in all, In my opinion, this possible is the best middle-sized aquarium for a Betta fish.Advantages:
- Hidden filter and pump in a back chamber
- Undeniably beautiful design
- LEDs will grow many low to medium-need live plants
- Has space for additional equipment and cords
- Does not include a heater
- The filter can be a bit strong for your Betta fish (you may need to replace the pump, in which case I suggest having a look at this inexpensive one)
- Pricy, considering that it provides an actual living space of 10 gallons for your fish, instead of 15
10. Tetra ColorFusion Kit – Affordable All-in-One Solution
Supposedly designed to house GloFish this fish tank is actually a really good fit for a Betta and, perhaps, some other fish companions.
It’s decently sized and though its looks are not something outstanding it is a really good beginner-level aquarium kit for new Betta owners.
It actually comes with a heater, which is a blessing, given the competitors’ aquarium kits. The included heater and the spacious 20 gallons of volume make the Tetra ColorFusion on of the best complete tank kits for a Betta fish.
The light that’s included in the pack can grow some low-tier live plants if you provide them with aquarium fertilizers.
The package actually includes plastic plants, but I think those look terrible and ugly (sorry!).
The colorful lights may stress your Betta fish so I suggest using only one constant mode and sticking to it.
The aquarium’s filter does the job as long as you’re not overstocking the fish tank, which is often tempting when you have anything above 5 gallons in volume.
Anyway, pay attention to the manufacturer’s instructions about installing the filter correctly, as many people seem to fail to do so.
It actually works nicely and quietly if you put it right and the general hint here would be to push it in harder until it clicks and fits.
The heater is a fixed temperature one, which may or may not be good for a Betta.
The one that’s included in this aquarium kit is made rather cheaply, and in my opinion, you should buy a separate unit to ensure a safe water temperature later on.
If I were you, I’d buy this fish tank If I wanted to pay less, but was prepared to compromise a little with the side accessory.
Nevertheless, the fish tank is a 20-gallon spacious one, is sturdy, made out of real glass and overall one of the best purchases for a Betta fish. You can always upgrade some of the parts down the road and the included ones will last you for the time being.Advantages:
- You won’t worry if your Betta feels confined in 20 gallons of water
- Comes with a filter
- Only aquarium on this list that comes with a heater
- Comes with fancy lights
- Sturdy, made from real glass
- Simplistic design if you’re into that
- Affordable for an all-in-one fish tank of this size
- Side equipment is not outstanding quality, so you may want to upgrade parts later
- A rather confusing assembly process
- Colorful lights are not something you’d want to use for your Betta fish tank
Choosing the best one with a certain volume
If available area at home is your major concern and you’ve already narrowed down your choice to a certain fish tank volume then this section is for you. I’ve made sure to arrange the reviewed products by their relative capacity bracket below. Have a look at the best Betta fish tanks in regards to gallon count:
1. Optimal small fish tanks for Bettas
All of these are 3 or 4-gallon fish tanks that have been reviewed above in this article. Though compact, they are generally considered enough in terms of space for a Siamese Fighting Fish. Here are the best small tanks for a single young Betta fish:
- Tetra LED Cube Kit with Pedestal Base – 3 gallons.
- biOrb FLOW Aquarium with Light – 4 gallons.
- Penn Plax Curved Corner Glass Aquarium Kit – 3.4 gallons.
These are all just about the absolute minimum size for housing a single Betta with perhaps a couple of snails and nothing more. You should not buy aquariums that are smaller than that.
2. Optimal 5-gallon fish tanks for Bettas
Each of these products has a separate review section above, so make sure to check that before you decide on a purchase. Have a look at the 6 best 5-gallon fish tanks for a Betta:
- Hygger Horizon -advertised as 8 gallons but holds 6, because of the 3D background.
- Penn Plax Curved Corner Glass Aquarium Kit – 5 gallons.
- MarineLand Portrait Glass LED Aquarium Kit – 5 gallons.
- Fluval Spec V Aquarium Kit – 5 gallons.
- Marina LED Aquarium Kit – 5 gallons.
- Fluval Edge – 6 gallons, but actual water capacity is probably 5 gallons.
Some of these come in more than one size, so keep that in mind.
3. Optimal 10-gallon fish tanks for Bettas
Here’s an overview of the 10-gallon fish tank kits that would best suit a Betta:
- Penn Plax Curved Corner Glass Aquarium Kit – 10 gallons.
- Marina LED Aquarium Kit – 10 gallons.
- Fluval Flex 57 Nano Glass Aquarium Kit – advertised as 15 gallons but only provides 10 gallons of usable space.
These are all a very good fit for an entry-level Betta owner.
4. Optimal 20-gallon fish tanks for Bettas
The selections below are ideal for a community tank. They will definitely be appreciated by your small fish pet. Take a peep at the best 20-gallon aquariums for a healthy Betta:
Get the larger one if you plan on keeping other fish companions
If you plan on housing your Betta fish with other fish in the near future you are definitely responsible for making sure it all goes well.
Contrary to the popular belief it is possible, but you need to make an informed decision.
Choose Betta tank mates wisely to make sure conflict is avoided.
In that case, it’s always better to go for the larger fish tank.
If you click that link you’ll see that the companion options are heavily dependent on tank size and the density of decoration and live plants.
Note that the Betta community setup is not a recommended one if you’re a complete beginner to the hobby.
Don’t forget to wait out the nitrogen cycle before putting live fish inside
If you don’t know what a nitrogen cycle is then pause reading here and do your research now.
This process usually lasts a month or so, but you can speed it up by using the right brand of bottled bacteria and my experience shows that Tetra SafeStart is a good choice for that.
Some of the kits listed above do come with a bottle included, so read the contents carefully.
It’s sad how many people rush the whole fish keeping thing just to find their fish dead in a couple of days.
Let your tank cycle and wait until the water parameters are safe and welcoming (0 ppm of ammonia,0 ppm of nitrite, 10-30 ppm of nitrate) or use bottled bacteria.
Bettas get stressed enough by being sold in jars at local fish stores.
Don’t make the rookie mistake of letting your impatience kill your new pet.
Over to you
It’s not difficult to make the right choice for a fish home. If in doubt – let your budget decide.
Mind that all of these are aquarium starter kits, meaning that they will probably include most all side gear.
Nevertheless, I made sure none of these will be cruel to a live fish, considering the tank’s size and quality of the equipment so you won’t regret your purchase.
I tried my best to select aquariums that have a filter because this is one of the most overlooked mistakes when someone is new to fishkeeping in general.
For a Betta fish to feel best in its new home, the fish tank should have the right amount of plants and decorations, be it small or big.
