How can you own an aquarium if you live in a small apartment or don’t have much room? Aquariums take up a great deal of space, even beyond the tank itself; filters, bubblers, heaters, and other parts can immediately over-crowd your home.

Luckily, as the FREESEA 1.4 Gallon Betta Aquarium shows, that doesn’t have to be the case. This tank can fit nearly anywhere, requires little to no maintenance, and can hold bettas or other small fish.

Unfortunately, that wasn’t every user’s opinion. Some aquarists might find the design to be too small, while some users had issues with the strength of the pump.

Even still, before you make your final decision, let’s take a closer look at the FREESEA 1.4 Gallon Betta Aquarium. It could hold features and design advantages that make it ideal for your needs.

FREESEA 1.4 Gallon Betta Aquarium: The Details


  • Weight: 1.86 lbs.
  • Dimensions: 7.8 x 7.8 x 5.5 inches.
  • Capacity: 1.4 gallons.
  • Lighting: LED lights inside the tank cover.
  • Glass or Acrylic: Acrylic.
  • Accessories: Two plastic plants, filtration sponge, pump, instructions, adapter.



The FREESEA Betta Aquarium holds up to 1.4 gallons of water. This capacity will suit a few bettas, other small fish, as well as sparse plants – but not much else.

The tank was designed to be compact, fitting in places where a regular-sized aquarium could never go. Additionally, the tank is made of acrylic and built to accommodate freshwater.

While it simply lacks the durability needed for saltwater, as this substance will corrode the tank, the pump, and the accessories that come with it, for freshwater duties, it’ll be a-okay.


The filtration system included with this FREESEA aquarium is rather simple. In total, it’s composed of a filtration sponge and a pump.

The pump operates by pushing water through the sponge, ensuring any particles are removed, before moving the water back into the tank.

It’s basic and straightforward but works to provide your tank inhabitants with the cleanest environment possible.


This FREESEA betta aquarium has a rather unique design. It comes in a half-moon shape with glass surrounding the full enclosure, along with a black partition blocking the filtration and pump from view.

Not many full-sized tanks bother hiding the pump and filter, so this is definitely an appealing feature.

This design also ensures it looks good in any type of décor, where it can be pressed flat against a wall or shelf if needed.

The Positives

Super Easy to Use

The FREESEA 1.4 Gallon Betta Aquarium could not be easier to assemble and use. Whether or not you’re an expert, you’ll be a-okay when it comes to getting this tank up and running.

Once you receive it, slide the black divider into the tank, just behind the fake plants. Attach the pump to the back of the divider and then secure the cover with the lighting onto the head of the tank.

Connect the pump to the back of the tank and add your water. After this, attach the power-plug to the tank and then into the nearest outlet. Slide the sponge filter into place along the black divider.

Once the aquarium is plugged in, the pump will begin working. Then that’s it – you’re ready to introduce your bettas to their new home! FREESEA ensures you won’t be fumbling about with your new aquarium.

Incredibly Compact

At only around 8 x 8 inches and at just under 2 lbs., this aquarium is highly compact. If you live in a small apartment or are otherwise short on extra space, this is the perfect aquarium for you.

It allows you to own fish or bettas in your home, but without sacrificing the amount of space a large tank demands. As a bonus, you won’t need a moving company to relocate this to a new home; just place your fish in a bag, empty the tank, and throw it in a box!

This opens up a variety of places that you can place your aquarium. Since it will only be taking up minimal space, you can easily keep this in a studio, dorm, or classroom. It also won’t weigh down a desk or table thanks to its lightweight design.

Very Easy Maintenance

There is almost no maintenance required on the FREESEA 1.4 Gallon Betta Aquarium. You need only wash out the sponge filter and replace it every couple of months.

At this point, you can also replace about ¼ of the water. Otherwise, just feed your fish and enjoy the view! There’s no hassle whatsoever.

This is great for both new and busy hobbyists. You won’t feel daunted by the maintenance that this aquarium needs. And an aquarium with little maintenance means your pets will remain happier for longer.

This is just another example of the convenience this small betta aquarium brings.

Amazingly Affordable

If you’re seeking an affordable aquarium, the FREESEA is an ideal fit. At under $50 on Amazon, it’s one of the most cost-effective aquarium kits on the market.

Since it’s so compact, very few materials go into its construction. While that reflects on the weight, it’s also reflected in the price. Now anyone can afford their own small aquarium and a home for their pets without breaking the bank.

This makes this aquarium great for those just starting out in this hobby, or those on a budget. You won’t feel forced to spend hundreds of dollars to get your pets into a happy home. This also means you’ll have more money to spend on accessories and extras for your tank.

Even with a super cheap price tag, you’ll still be entitled to a replacement should your aquarium not arrive as advertised. You’ll simply need to contact customer service if your tank is broken or doesn’t work, and they’ll issue a refund or substitution.

Really Quiet

Filtration is crucial, but a loud pump is annoying. While that’s to be expected in some tanks, luckily, the FREESEA lacks this problem.

We loved how quiet the pump is. If it weren’t for the bubbles in the water, we’d question if it even worked. The tank remained clean, but there was no whirring to irritate users.

If you’re placing this in a bedroom or a child’s room, there’s no danger of this pump keeping you up at night. As such, this opens a variety of places where you can put this aquarium.

And since it’s so easy to move around, you won’t have to worry about it stirring up a ruckus no matter where it’s left.

Perfect for Beginners

Thanks to this aquarium’s easy-to-use design, affordable price, and easy maintenance, it’s the perfect recipe for a beginner’s aquarium.

Those new to this hobby won’t feel daunted by anything to do with this aquarium, making it a great place to start.

Thanks to its super convenient build, this also makes this fish tank great for classrooms and children! There will be little to worry about. Together, with its affordable price, beginners have much less to fuss with all around.

The Negatives

Space Issues

Some testers were upset about the amount of room their fish or bettas had inside the tank. Because of the divider that hides the pump and the filtration from view, the area within the tank is rather limited.

They don’t have the whole 1.4 gallons to swim. Be sure you’re aware of this before purchasing it. Some fish require more space to move about freely and stay healthy.

Just be sure you take note of how much space your pets require before purchasing this aquarium.

Inexpensive Parts

Depending on what you’re after in an aquarium, some users may have some reservations about the quality of the parts included with this tank.

Don’t expect the parts to be as high-quality as more expensive aquariums. While the aquarium does its job, the pump, divider, and other tank parts may not live up to the likes of pricier tanks.

Remember, at only $30, you’re purchasing a compact and straightforward tank kit, not one that’s overly high in quality.

Pump Flow

There’s also a chance that your pump may be too strong. Considering the size of the tank, its water flow rate is a bit excessive.

If a pump is too strong, fish owners risk their bettas getting pushed against the back wall of the tank, struggling to comfortably navigate the small area.

As such, depending on your setup, it may be worth investing in a different pump with a softer flow rate, so your fish can enjoy a clean but less stressful environment. With a price this low, you can use the extra money to purchase a more suitable pump.

Overall Verdict

After going over all the positives and negatives, we do recommend the FREESEA 1.4 Gallon Betta Aquarium.

With its compact shape, easy set-up, quiet pump, and affordable price tag, there’s a great deal to appreciate about this kit. Even the maintenance is low-effort, ensuring you can enjoy a busy life while still owning fish.

With that said, you may want to buy a weaker pump, and should handle the tank carefully to avoid damaging the low-cost build.

Otherwise, this aquarium should be the ideal place to house your fish. What more could you ask for? If you’re in the market for a new aquarium, this FREESEA is definitely worth checking out.
