Last update on 2021-05-12 / Affiliate links / Images from Amazon Product Advertising API


The Aqueon Aquarium 10-Gallon Starter Kit is our #1 top pick, and here’s why.

This aquarium kit is perfect if you’re looking for a ten-gallon fish tank because it’s easy to set up and comes with all the accessories and tools you need to get started straight out of the box.

Unlike many other 10-gallon fish tank kits on the market, the Aqueon Aquarium Kit comes with a heater and a thermometer to measure water temperature.

Beyond that, this aquarium kit also comes with fish food, a water conditioner, a filter, and even a red LED light that flashes when your filter needs changing—no more guessing or going too long without changing out your filter!

For lighting, the Aqueon 10-Gallon aquarium kit has an attached LED light that you can keep on in the day and turn off at night.

Another benefit is the super-advanced 5-step filtration system that by far beats out any other competitors on the market.

The filtration system also includes an ammonia filtering pad to keep water even more clean and healthy for your fish.

The only issue you may have if you’re entirely new to fishkeeping is that you need to pay attention to the water temperature.

The Aqueon tank does come with a heater, and the thermostat is automatically set to 78 degrees and can not be adjusted easily.

While a 78-degree temperature is sufficient for most fish, if you have tiny fish or baby fish, the climate could be too hot and cause problems.

For everything you get in this 10-gallon tank kit for the price, the heating consideration is likely to be minor.

If you’re looking for a one-stop solution to getting started with fishkeeping straight away, the Aqueon Aquarium Starter Kit is hands-down the best option.


Manufacturer’s Specifications

  • Material: Glass
  • Dimensions:  14 x 23.75 x 16.5 inches
  • Weight: 17.5 Pounds
  • Includes: aquarium, hood, filter, filter cartridge, heater, fish food, water conditioner, fish net, thermometer


What We Like

  • Contains everything you need to get started (comes with a heater, unlike other options)
  • Attractive price for everything you get
  • Flashing light to let you know you need to replace your filter


What We Don’t Like

  • Preset temperature on heater not suitable for all fish
  • LED lighting is simplistic
  • Not a fancy design – simple rectangle design but nothing frilly



If you’re looking for an affordable fish tank that has everything you need to get set up straight out of the box, the Aqueon Aquarium Starter Kit is probably the best option.

You won’t need to purchase anything other than aquarium décor and fish if you go with this tank, which is a massive plus for a total newbie to fishkeeping.

Just make sure the fish you intend to keep inside the aquarium can thrive in 78-degree water, and you’ll be on your way to fish keeping heaven!


2- Marina LED 10 Gallon Aquarium Kit

Last update on 2021-05-12 / Affiliate links / Images from Amazon Product Advertising API


Next on the list is the Marina LED 10 Gallon Aquarium Kit.

If you’re new to aquariums and fish tanks, you will love this kit because it has plenty of accessories and add-ons that create the perfect environment for your fish to thrive.

The Marina LED 10 Gallon Aquarium Kit holds up to 10 gallons of water and is perfect for total newbies because it comes with everything you need to get started fresh out of the box.

Included in the kit are a filter, fishnet, water conditioner, fish food, and a gorgeous LED light that you can adjust depending on the time of day to create the best environment not just for your fish – but the perfect ambiance for your living space, too!

Another impressive addition to this aquarium kit is the biological water supplement, which means you can use tap water from your kitchen or bathroom to fill your tank, and rest assured that your fish are safe and healthy.

Many other kits leave this out. But it’s something you would need to purchase separately otherwise.

The Marina 10 Gallon Aquarium Kit also includes a handy aquarium setup and essential care guide, assuring that even the most novice fish keepers can get their aquariums set up just the way they need.

While the Marina LED 10 Gallon Aquarium Kit boasts many features and accessories that make it a decent choice for beginners or small spaces, it is a bit more expensive than other tanks and kits on the market.

However, if you can swing the extra bit of cost, it’ll save you time and money down the line.


Manufacturer’s Specifications

  • Material: Glass
  • Dimensions:  20″ L x 10″ W x 12.5″ H
  • Weight: 17.3 pounds
  • Includes: Marina Slim S15 clip-on filter with quick-change filter cartridges


What We Like

  • Includes many accessories you’d need to purchase separately (fish food, water conditioner, biological supplement, fishnet)
  • High-quality materials (durable glass, cover, bright lights)
  • Very easy to set up


What We Don’t Like

  • Does not come with a heater



If you’re looking for a great fish tank option, the Marina is an excellent place to start. Note that you will have to buy a heater and stick-on thermometer to control water temperature, but other than that, the Marina is an attractive option.


3- Hagen 15004HG Fluval Flex Aquarium

Last update on 2021-05-12 / Affiliate links / Images from Amazon Product Advertising API


Next on our list of the best 10-gallon aquariums is the Hagen 15004HG Fluval Flex.

The first thing you’ll notice about the Fluval Flex is that it’s not a 10-gallon aquarium. Knocking off an extra gallon, it holds 9 gallons of water.

If you’re willing to forego that extra gallon, you’ll have an excellent option on your hands, as you’ll soon see.

First, the Fluval Flex has a distinct design – it’s not your run of the mill standard rectangle-shaped aquarium.

It looks more like an art sculpture that you’d find in a museum with beautiful, curved edges.

If you’re looking for something compact, light, and attractive to get you started keeping fish, the Fluval Flex is one of the best on the market.

The glass shape makes this small, compact aquarium look much more massive, giving a bigger, more clear view of your fish, making them far more enjoyable to watch.

Another benefit is the unique three-stage filtering system, far better than filters that come with other 10-gallon aquarium kits.

The Fluval Flex filtration system uses mechanical, biological, and chemical media to clean the water thoroughly, making for a better environment for your fish.

Next, the remote-controlled LED lights will turn your aquarium into a work of art.

With the click of a few buttons, you can try all sorts of eye-pleasing color and effect combinations for your lighting.

The unique design, coupled with the Fluval Flex’s ultra-bright fully remote-controlled LED lighting system, provides a stunning aesthetic for your home and the perfect environment for your pet fish to thrive.

Additionally, the glass’s premium manufacturing quality is sure to impress, as is the powerful 3-stage filtration system that will keep your water in tip-top shape.

What stands out most about the Fluval Flex is the unique design and lighter weight of the aquarium.


Manufacturer’s Specifications

  • Material: Glass
  • Dimensions:  0.39 x 0.39 x 0.39 inches
  • Weight: 11.1 pounds
  • Includes: 3-stage filtration, remote control LED lighting, built-in hood
  • Notes: modern, unique design that stands out from the rest


What We Like

  • Unique design that makes fish appear larger
  • Lightweight
  • 3-stage filtering system
  • Remote-controlled LED lights


What We Don’t Like

  • 9 gallons instead of 10



If you’re looking for a high-quality 10-gallon fish tank setup with gorgeous, modern design, consider the Fluval Flex.


4- Penn Plax Curved Corner Glass Aquarium Kit

Last update on 2021-05-12 / Affiliate links / Images from Amazon Product Advertising API


If you’re searching for another attractive 10-gallon aquarium option, The Penn Plax Glass Aquarium Kit may be your speed.

The Penn Plax Glass Aquarium has unique, curved glass corners that create an unobstructed view of your fish from any angle – even the top.

There is a convenient hinge on the top of the aquarium that makes it extremely easy to set up and maintain.

The kit also comes with a convenient clip-on LED light that hooks to the top of the tank.


Manufacturer’s Specifications

  • Material: Glass
  • Dimensions:  17.75 x 11.75 x 12.63 inches
  • Weight: 19.25 pounds
  • Includes: internal filter, LED light, mat, and hinge style plastic lid


What We Like

The Penn Plax Curved Corner Glass Aquarium Kit is an excellent option because it is so easy to set up in a three-step process:

1) Use included hinges to attach the lid to the top of the tank.

2) Clip the included LED light to the top of the tank and plug it into the nearest outlet.

3) Attach the included filter to the inside of the tank, fully submerge the filter in water, and add your fish!


What We Don’t Like

  • While the tank is high-quality, included accessories are less durable.
  • Expensive relative to included items.



Beyond ease of use, the quality of the fish tank alone is far above that of competitors. The glass is thick, durable, and easy to clean, which makes it an incredible value. But if the price is of major concern, you may get more bang for your buck elsewhere.


5- Aqueon 10-Gallon Fish Tank Only

Last update on 2021-05-12 / Affiliate links / Images from Amazon Product Advertising API


So far, we’ve only reviewed 10-gallon aquarium kits.

Generally, you will find a great deal on great products if you go the route of getting aquarium kits, mostly because they tend to have all or most of the components you need to set up your fish tank without too much fuss.

However, in some cases, you may want to forego the option of getting a kit and opt for purchasing just the actual aquarium instead.

For example, maybe you realize that the heater included in the aquarium kit would make the water too hot for your fish of choice. Or you have different lighting or filtration needs.

If you know for sure you’d need to purchase additional components anyway; it makes perfect sense to get a high-quality tank at an affordable price.

That’s where the Aqueon 10-Gallon Aquarium comes in.


Manufacturer’s Specifications

  • Material: Glass
  • Dimensions:  14 x 23.75 x 16.5 inches
  • Weight: 14 Pounds
  • Includes: aquarium – all other items sold separately


What We Like

  • High-quality glass tank
  • Attractive price
  • Freedom to choose accessories


What We Don’t Like

  • Aqueon products notoriously only work with other Aqueon products.



With the Aqueon 10-gallon tank, you have flexibility with the accessories and add-ons that you need. But the flexibility itself is limited to Aqueon.

For that reason, we do recommend you get a full aquarium kit. That way, you get everything you need in a straightforward package and don’t have to worry about finding specific Aqueon products separately.

In case you would like to go this route. However, we include the appropriate bare-minimum products you need to accompany the Aqueon 10-gallon tank in the next section.


Aqueon Aquarium Accessory Recommendations

1- Hood

As some fish like to jump and you don’t want them jumping out of the fish tank, you’re going to need a hood.

We recommend the Aqueon Aquarium AAG29020 Versa Top, 20-Inch, as it fits perfectly with this tank.


2- Lights

Lighting is a critical component when building the perfect aquarium, not just for the fish but for any plants you’d like to include as well.

Luckily, you have more options for lighting than you do for other parts of the Aqueon tank. Any 20-inch LED light with extendable brackets will do.

However, if you’d like a specific product recommendation, we suggest you opt for the NICREW ClassicLED Aquarium Light, as the size, brightness, power, and functionality is of the highest quality.


3- Filter

When choosing a filter for the 10-gallon Aqueon tank, make sure you choose one that can filter 4x the water volume. So, select a product that can filter 40 gallons of water per hour.

Our official recommendation is the Aqueon Quietflow Internal Power Filter, as it is quiet, small, easy to use, and will work well with your Aqueon Aquarium (same brand name).


4- Heater

Finally, should you opt to build a tropical aquarium, you will need a heater for your fish tank.

You will need a 50-watt heater to warm the water in a 10-gallon tank evenly.

We recommend the Aqueon 50-Watt Pro Adjustable Heater because it is easy to use, well-priced, part of the Aqueon family of products, and is calibrated for ultra-precise temperature settings.



10 Gallon Fish Tank Buying Guide



Why Should You Buy A 10-Gallon Fish Tank?

With all the different options for fish tanks around, you may wonder why you should consider a 10-gallon tank in the first place.

Well, if you’re buying a fish tank for the first time, just want to add a tank for your collection, or enjoy a nice-sized tank for a smaller space, the 10-gallon tank is a perfect size.

Here are just a few reasons why a 10-gallon aquarium is such an excellent choice for many fish keepers.


  • You can create the perfect habitat for many species of fish.
  • 10-gallon tanks work well for smaller spaces.
  • They come at attractive price points for beginners. You won’t have to invest too much money to see if fishkeeping is for you.
  • The smaller size means it takes fewer design items to create an attractive tank.


Things To Look For In A 10-Gallon Fish Tank

You must make several considerations when purchasing a 10-gallon tank. Below, we will cover four of the most critical aspects to make sure you pick the best option to build the perfect aquarium.


1- Fish Types

First and foremost, consider the species of fish that you plan to keep. Not all fish are suitable for every sized fish tank.

Furthermore, space considerations may limit the number of fish you can keep in a 10-gallon aquarium. You will be able to fit fewer larger fish than you will smaller ones.

Additionally, the type of fish you wish to keep may determine the additional accessories you need to accompany your tank.

For example, if you want tropical fish, you definitely need a heater to maintain warmer temperatures. Yet some fish tank kits like the ones we reviewed in this article come with heaters, but you still need to make sure that they will be adequate for the fish you want.

Check out our detailed list of the best fish for a 10-gallon aquarium!


2- Quality

Next, you must consider quality when purchasing a fish tank.

Some fish tanks are lower-priced, but they are made of defective materials, poorly put together, leak, have toxic materials, or even come poorly packaged.

You want to make sure you get a high-quality product for your money.


3- Included Accessories

Next, once you determine the types of fish you want to keep, and what they need, you’ll have a more accurate picture of all the accessories you will need to buy.

Many kits like those we’ve reviewed for you come with almost everything you need to get started straight out of the box.

But you still need to do your due diligence to make sure you have all the necessary components.

You will need the fish tank, lighting, a filter, and usually a heater at the bare minimum.

Some aquariums and aquarium kits seem like great deals, yet you don’t want to be surprised to find you need a critical piece before you can have the perfect fish tank setup.


4- Price

Finally, while you should not purchase a fish tank based on price alone, you should set your available budget and choose the fish tank that fits your budget without compromising quality.

10-gallon tank prices vary according to size, shape, included accessories, and durability of materials.

Luckily, you can find high-quality fish tanks at a wide range of price points.

Keep in mind, however, that fishkeeping is not a one-and-done scenario.

Expenses don’t stop once you set up your fish tank.

You’ll also have to maintain the aquarium and the ecosystem inside of it. That’s just something else to think about when you set the budget for your new aquarium.


Different Types of 10-Gallon Aquariums

There are two primary types of 10-gallon aquariums you can buy, classified by the material. Generally, aquariums are either glass or acrylic.


Glass 10-Gallon Fish Tanks

Glass is the most common fish tank for many reasons. First, glass tanks are generally high-quality with ergonomic features that many aquarists have come to appreciate.

The most significant advantage of a glass aquarium is the crystal-clear appearance. The clarity is attractive for fish viewing.

Another critical reason why glass is such a popular fish tank material is that glass is highly durable – lasting for years.

Furthermore, a high-quality glass tank can be an affordably priced option for budget-conscious aspiring aquarists.

The downside of owning a glass fish tank, however, is that glass tends to be heavier.

So, if you’re sticking it on top of a shelf or stand, you need to consider weight.


Acrylic 10 Gallon Fish Tanks

The second option, an acrylic 10-gallon tank, is a replica of a glass fish tank.

Acrylic tanks look so similar to their glass counterparts that you can’t even tell unless you know what to look for.

If glass and acrylic fish tanks are so similar, you may wonder why you’d select an acrylic fish tank at all.

One reason is that acrylic fish tanks are lighter than glass.

Another is that glass tends to be less customizable, meaning most glass fish tanks will have your standard rectangle shape.

On the other hand, acrylic fish tanks come in many beautiful, unique shapes and sizes that can make for attractive displays in your home or office.

However, a significant downside of acrylic fish tanks is that they can be more pricey than their glass competitors. Additionally, acrylic tanks aren’t scratch-resistant.

If you’re budget-conscious and just want a fish tank that looks great, will last longer, and can get you started right away with confidence – a glass tank is probably your best bet.



How To Setup Your New 10-Gallon Aquarium

Now that you’ve picked the perfect fish tank, it’s time to set it up!

Most fish tank kits like the ones reviewed in this guide come with instructions that you should follow.

But just so you know what to expect, here is the step-by-step process for how to get your new aquarium set up quickly and easily.

First, make sure you have all the equipment you need handy. This includes the tank, hood, lights, filter, heater, decorations, and your fishnet.

Then, make sure you thoroughly clean your tank to ensure there’s no residue or chemicals from packing. There might be invisible toxic substances that could harm your fish – you don’t want that!

Once the fish tank is clean, add the gravel, rocks, or substrate to the bottom.

Next, add and position plants and other decorations to the aquarium, adjusting them to your liking.

Once your decorations are all set, fill the tank with purified water, following your tank or water filter instructions. Make sure you leave at least 1-2 inches of space at the top of the tank – don’t overfill.

Then, set up your lighting, heater, and thermometer if you’re using one, and turn everything on to make sure it works.

As the last step, make sure the water temperature is just right for the type of fish you plan to add to the tank. And make sure any other requirements are met based on the instructions included with your aquarium kit.

Generally, you want to wait at least 24 hours before adding fish to the tank to make sure everything is in working order and the environment is stable.

Start by adding a few fish at a time, gradually growing your tank as you learn more about fishkeeping and get used to maintaining the aquarium.


10-Gallon Aquarium FAQ’s


In this section, we’ll cover some of the top questions people have about buying 10-gallon aquariums for your pet fish.


1- What is the best 10-gallon tank for 2021?

Our official recommendation for the best 10-gallon fish tank for 2021 is the Aqueon Aquarium Starter Kit with LED Lighting.

2- What fish can you keep in a 10-gallon aquarium? (Stocking Ideas)

You have many options for the types of fish you can keep in a 10-gallon tank.

Generally, you can keep any fish that are within the one to two-inch size range, provided they are not aggressive and will play nicely with others.

That said, betta fish, danios and barbs, tetras, dwarf corydoras, and guppies make for a great start to any new fish tank.

One word of warning: make sure you know the full adult size of any fish you choose. The last thing you want is to bring home baby fish that seem to fit well but will soon outgrow your setup!

Check out our official list of the best fish for a ten-gallon tank, for more info!


3- How do you clean a 10-gallon fish tank?

Cleaning your new 10-gallon fish tank is simple. Your primary concern is eliminating algae. Scrub the algae away, remove 15% of the water from the tank, clean the gravel at the bottom, then top off the tank with de-chlorinated water.


4- How many fish can fit in a 10-gallon fish tank?

The number of fish you can keep in a 10-gallon tank depends on the size of the fish you plan to include.

As a general rule, stick to one fish per gallon, especially if you’re just starting out. You can slowly add up to three small fish per gallon over time. But you want to make sure you gradually add more fish. The last thing you want to do is to overcrowd your fish by adding too many too quickly and causing unnecessary stress.


5. How much does a 10-gallon aquarium weigh?

Out of the box, a 10-gallon tank weighs somewhere between 10 and 20 pounds. But when you add water, the average weight of a 10-gallon aquarium is a whopping 111 pounds!

Therefore, make sure you plan to store your fish tank in an appropriate, safe location. Avoid stools and tables, as they are not strong enough to support the weight.

It’s best to purchase an aquarium stand if it fits your budget. That way, you know for sure that your new aquarium setup is just right.


6. How full should a 10-gallon tank be?

While it may be tempting to fill your fish tank to the top (after all, more water volume = more fish!), this is likely not a good practice in the long-run.

For starters, you may have issues with water overflow, splashing, or even your pet fish escaping the tank.

You can use an aquarium lid, but doing so may restrict airflow to your tank.

We recommend leaving at least an inch or two of space at the top for best practices.




A small 10-gallon aquarium is a beautiful addition to any small space, yet, selecting the right equipment for your needs takes a bit of consideration and research to get right.

Once you find the perfect setup, both you and your fish will be happy with the outcome.

We hope our review and buying guide has taken some of the guesswork and confusion out of the process and that you can get started right away with creating the perfect setup for you and your finny friends.

Best of luck!
