The Best 20 Gallon Fish Tank for 2019

best 20 gallon fish tank

The 20 gallon tank has been called many names, but one that truly stands out is “The best beginner tank”, as some would call it. In many ways, that statement is true. As an entry-level tank, it is quite affordable, and it is easier to set up. The main reason for this is that most 20 gallon tanks are sold as a set, meaning that the package includes other items needed for the aquarium as well, like the lighting, the heater, the filter, etc. If you’d like to try it out, here’s a list of the best 20 gallon fish tank that I have tried.

Best 20 Gallon Fish Tank Reviews 2019

1. Aqueon LED Aquarium Kit

Aqueon LED Aquarium Kit 20H Black

20 gallon tanks with complete setup are perhaps one of the best things that a fishkeeper considers a “good find.” If you are looking for a 20 gallon aquarium kit that you can use in your own place, the best 20 gallon aquarium that you can purchase is the Aqueon LED Aquarium Kit 20H Black.

One of the features that I appreciate about this aquarium kit is the filter. It has an excellent three-stage filtration system. It effectively keeps harsh chemicals which could stain the water or poison my fish and plants, filter out undesirable particles such as small pebbles and fish food, and harmful organisms such as bad bacteria and fungi which could compromise the health of my aquatic pets. Furthermore, it operates very quietly. The filter’s sound doesn’t disturb the peace and quiet inside my home office.

Another admirable feature of this aqueon 20 gallon kit is the LED lighting. The white glow not only illuminates the contents of the tank but also bring out otherworldly beauty. In addition, the LED hood equally distributes the light inside the tank and prevents it from spilling outside.

What I find disappointing about this tank kit is the absence of hinge on the LED hood. Every time I feed the fish, I always have to lift the whole hood just to have complete access to the tank. I wish there was a way to just simply lift one side of the hood the other remains on the other side without having to exert tremendous effort. I believe that a hinge will rectify this issue.

Pros
  • The filter works quietly
  • The filter has an excellent three-stage filtration system
  • Has an awesome white LED light
  • Has a reliable and low profile LED hood
  • The filter has an LED indicator that informs when to change cartridges
  • Has a preset heater
  • With free fish net, water conditioner, stick-on thermometer, and fish food
Cons
  • The LED hood has to be taken off completely
All in all, I can honestly say that the Aqueon LED Aquarium Kit 20H Black is an excellent product. It has everything that a hobbyist needs: a sturdy 20 gallon glass tank, filter, LED light, a preset heater, and an LED hood. The package comes with free fish food, water conditioner, a stick-on thermometer, and a fishnet. These freebies will definitely save any fishkeeper a great deal of money in the long run.

2. Tetra 20 Gallon Complete Aquarium Kit

Tetra-20-Gallon-Complete-Aquarium-Kit

If you are searching for a reliable and durable aquarium kit that offers all the convenience that you need as a fishkeeper, the most ideal product that you should try is the Tetra 20 Gallon Complete Aquarium Kit w/Filter Heater LED & Plants.

There are so many things to like about this particular 20 gallon aquarium kit. First is the LED lighting. It has a natural light condition that illuminates the inside of the tank. The effect is truly mesmerizing because it is as if I am looking at the tank during the daytime. The LED hood does a magnificent job of keeping the light inside.

I have observed that the tank is scratch-proof. This is a good feature because it protects the glass from scratches due to accidental contacts with pointy objects. This also prevents the tank from breaking. This is a very important feature to me because my children have a pet cat. Its claw can really scratch the surface of the glass tank.

Meanwhile, the filter performs admirably. It has a three-stage filtration system that keeps the water clean and clear at all times. Because of this, my aquarium doesn’t have floating particles, harsh chemicals that could stain the water and cause a bad smell, and harmful organisms which could affect the health of the fish inside.

The heater is another feature that I consider absolutely beneficial. It saves the fish from freezing during harsh winter temperatures. Without this added bonus on the aquarium kit, I wouldn’t have to keep replacing my precious pets again and again.

What I consider this product’s shortcoming is that the filter seems a little small for the aquarium.

Pros
  • The tank is scratch-resistant
  • Has an LED lighting
  • Has an LED hood
  • Has a preset heater
  • Has an excellent filter
  • Includes artificial plants
Cons
  • The filter seems a bit small for the tank
Considering all of the important information discussed above, I can safely say that the Tetra 20 Gallon Complete Aquarium Kit w/Filter Heater LED & Plants is a terrific product. It has every feature a hobbyist need: a sturdy 20 gallon tank, an excellent filter, luminous LED lighting with hood. The heater is also a marvelous addition to the package. Finally, it has artificial plants that could help you decorate the inside of the tank.

3. Marina LED Aquarium Kit

Marina-LED-Aquarium-Kit

When it comes to a 20 gal fish tank kit, nothing beats the features offered by Marina LED Aquarium Kit. If you are searching for the best tank kit, it is a wise decision to include this product in your shopping list.

What I really appreciate about this 20 gallon tank kit is the presence of an amazing filter. I can always count on this little aquatic machine to remove any standing particles, harsh chemicals, and harmful organisms through its three-stage filtration system.

The heater is another reliable tool included in the package. I can rely on this tiny contraption to prevent the fish from freezing during critical moments of the winter season. Other aquariums don’t have a heater included in the kit, that’s why I had trouble finding the perfect one that will complement the design of the tank.

Another exciting feature of this tank kit is the LED lighting. The light is very cool the eyes; it is neither glaring nor dim. It’s just very perfect for the size of the tank. The lights are very inviting, warm, and pleasing. Once the LED is turned on, it becomes a very magnificent decorative piece that can bring beauty to any living space in the home.

What I don’t like about this aquarium kit is how the fish food floats on the surface of the water. The remaining fish food just clutters the water as it waits to be filtered. Inasmuch as I want to give my fish a little amount of food to prevent it from clouding the surface of the water, they would easily get hungry. Then, I would have to dedicate another part of my time just to see that the fish are well-fed.

Pros
  • Has an excellent filter
  • Has a preset heater
  • Has an LED lighting
  • Has an LED hood
  • Has a water conditioner
  • Has a free fishnet
  • Comes with free fish food
Cons
  • The fish food floats and clouds the surface of the water
After taking all of the important information into account, I can say that the Marina LED Aquarium Kit is a terrific product. It has every item that both beginner and seasoned hobbyists are looking for: a reliable 20 gallon tank, a good filter, a heater, and LED lighting with a hood. The package also comes with a water conditioner so that tap water can accommodate the fish. If you need to have a 20 gallon aquarium kit immediately, then this product will provide you a smooth fishkeeping experience.

4. Aqueon 30X12X12 Fish Tank

Aqueon-Tank-Black-30X12X12-20L

For those who are looking for a sturdy and reliable blank tank only, the best one in the market is definitely the Aqueon Tank Black 30X12X12 20L.

I admit that this is a little different from the other brands that come with complete 20 gallon fish tank accessories. This gives me an opportunity to experiment and expand my decorative horizons. While I can’t put different species of fish together, I was able to try different gravel and corals as part of aquarium decoration.

Another benefit that I get from purchasing just a blank tank is the chance to breed some of my fish. Because of an empty 20 gallon tank, I was able to successfully breed my guppies. Now, I can give two to three guppies to my friends, relatives, and neighbors who are also into fishkeeping.

What I don’t like about this open 20 gallon tank is how it easily gets dirty. Since the tank has no canopy or hood, dirt and other free-falling particles can get into the water easily. Also, fish and snails can easily escape through the opening. One time, a lizard pooped and it went straight into the open aquarium. The little guppies thought it was fish food and they munched it straight away. So right now, I’m using an improvised cover made from a discarded plywood just to keep the tank covered all the time.

Pros
  • Comes with black and oak styles
  • The glass is durable
  • Lightweight
  • Lets natural light in to help plants thrive
Cons
  • It gets dirty easily because it has no cover
  • Fish and snails can easily jump out
After listing all of the advantages and disadvantages, I conclude that the Aqueon Tank Black 30X12X12 20L is a great tank kit. Despite being only a tank, it is a perfect space for breeding fish, for experimental decoration, among others. The tank is made from durable glass so you don’t have to worry about replacing it very soon.

5. Marineland AMLPFK20B Biowheel Aquarium Kit

Marineland-(Aquaria)-AMLPFK20B-Biowheel-Aquarium-Kit-with-LED-Light

If you want to succeed in your fishkeeping endeavors, the best tank kit that you should have is definitely this one.

What I appreciate about this 20 gallon fish tank starter kit is the scratch-proof tank. With this, I am confident that sharp and pointy objects won’t damage the surface of the glass which could lead to other untold incidents. Another thing that I truly applaud is its lightweight feature. Even my twelve-year-old child can carry it without breaking a sweat.

Another feature that I like is the LED lighting. It illuminates the contents of the tank properly. In addition, its glow provides an additional decorative effect on any space where the tank is installed. Meanwhile, the filter provides a phenomenal job of keeping the water clean and clear all the time. Its three-stage filtration system is truly remarkable. It keeps harmful organisms, harsh chemicals, and floating particles away from the water.

While the glass tank is scratch-proof, it is not entirely durable, which I find very disappointing. I have accidentally broken it when I gave it a little push. The water spilled all over the floor of my living room.

Pros
  • Has a scratch-proof tank
  • Lightweight
  • Has an efficient filter
  • Has an eye-pleasing LED lights
  • Comes with a heater, water conditioner, fishnet, and fish food
Cons

If you want to kickstart your fishkeeping hobby, this is the perfect product that you should try.

6. Elive Aqua Duo 20 Gallon LED Kit

Elive-Aqua-Duo-20-Gallon-LED-Kit-Aquarium-Starter-Kits

The idea of recycling the dirt filtered out from the water to be used by a plant is part of a wonderful concept called aquaponics. Imagine your tank filter giving the important nutrition to your precious plant. If you are into aquaponics, you will certainly love the Elive Aqua Duo 20 Gallon Aquarium Starter Kit.

There are so many things that I like about this aquarium kit. First is the magnificent LED light. It illuminates the tank magnificently. It brings a whole new level of beauty to the aquarium that not only I appreciate, but the guests as well. This tank becomes a wonderful piece of decoration at night.

Another phenomenal feature of this aquarium kit is the filter. I gotta say, the filter is truly a work of art. It is designed to sustain important nutrients to a plant while delivering a top-notch performance of maintaining cleanliness inside the tank. Although I admit that I’m entirely new to aquaponics, this aquarium kit really made me interested in pursuing it.

The other freebies included in the package that I find really nice are the fishnet, the media bag, and the free Hydrocorn. With this plant, I can grow a plant using the free-floating elements in the water that are considered waste will be feeding the plant on top of the tank.

What I find very disheartening is the fact that this product cannot be easily ordered in any store. It took me a while to track down this particular aquarium kit being sold online (Amazon should always be the first place anyone should look). I guess aquaponics is still trying to make its way into the mainstream market.

Pros
  • Has an excellent filter made for aquaponics
  • Has a sturdy tank
  • Has an integrated LED light
  • Includes a hydrocorn
  • Includes a media bag

7. SeaClear Acrylic Aquarium Combo Set

SeaClear-Acrylic-20-gal-Rectangular-Aquarium-Combo-Set

If you are tired of using glass tanks as aquariums, there is one great alternative that you will really enjoy using. Presenting the SeaClear Acrylic Aquarium Combo Set: the perfect tank to replace your traditional aquariums.

There are many things that I really like about this product. First is the material. Honestly saying, it’s nice to see a little break from seeing glass tanks inside the house. The acrylic feels good to touch and very reassuring that it won’t break easily even if it falls to the ground. I can even lift the whole tank with water and the contents inside.

Another amazing thing about this product is the rounded corners. They are a very good way to protect the tank against overly energetic kids and pets. This feature also adds aesthetic value which I find very pleasing to the eyes.

Meanwhile, the tank can accommodate freshwater and saltwater. I don’t see any hard water buildup on the acrylic surface whenever I’m cleaning it. Similarly, I don’t see any salt buildup on any corners of the tank during maintenance periods. Very easy to set up and maintain, it doesn’t take too much time during cleaning. This really is a good tank for busy people.

The LED light is also commendable. It is housed in a canopy that can be moved through a hinge. I really like how the cover easily moves and prevents the fish and snails from escaping the tank. It is also a good way to prevent unwanted objects from entering the tank which could be mistaken for fish food.

While this aquarium kit is truly amazing, there is one thing that I don’t like. It’s how it lacks steady support for the bottom. Whenever I’m lifting this acrylic tank, I always use makeshift support made from a discarded 2-inch laminated board. This way, the bottom won’t sag and spill the water out of the tank.

Pros
  • Lightweight
  • Durable
  • The front corners are curved
  • Ideal for freshwater and saltwater fish
  • Has an integrated LED light within the canopy
Cons

Are you looking for a dependable 20 gallon tank to add to your collection? The Aq Ascent LED Kit 20g will provide your fish with the best fish keeping experience.

I love so many things about this particular aquarium kit. First is how organized the LED’s wiring. The manufacturers really thought about the safety of the fish tank owners. If the wires were not as organized like this, it could certainly get exposed to the water and cause an untold possibility of an accident.

Speaking of LEDs, I love the way the canopy opens up like a hatch. It functions as a cover to prevent the fish from jumping out of the tank, and stop foreign objects from mixing from the water. I could open it to feed the fish without exerting too much effort.

Another feature that I really like is the contoured corners. Aside from keeping the children safe against accident, it really accentuates the design of the aquarium. It makes the whole tank interesting to look at.

The last thing is the completeness of the package. It has everything a fishkeeper needs: free Premium fish food, water conditioner, and a filter cartridge. This certainly frees me up with monthly expenses of maintaining the fish.

While I consider this 20 gallon tank awesome, there is one thing I wish the manufacturers included in the package. It is the cover.

Pros
  • Durable
  • Diamond-polished corners
  • The glass is distortion-free

What To Look For When Buying A 20 Gallon Fish Tank

20-gallon-long-aquarium

With the 20 gallon tank’s size, it is fairly easy to plan set up a design or theme, just as it is quite versatile in terms of fish stocking.

With such potential in an average tank, how do you choose the right one for you? Here are some of the factors to consider when looking for the perfect 20 gallon tank for you.

Choosing The Right Dimensions

With a fish tank that is as versatile as the 20 gallon tank, there are sure to be some variations. The first one and probably the most common among the three is the 20 gallon long tank. With dimensions of 30 x 12 x 12, it is often chosen to be a reef tank because of its orientation. With loads of space for decorations, a theme that is meant to be wide can be highlighted with this 20 gallon tank.

Up next is the 20 gallon high tank, which is measured at 24 x 12 x 16. Its tall stand makes it beautiful for designs with a number of layers, for example, taller live plants. Lastly, there is the rarer 20 gallon EXTRA high tank, sitting at 20 x 10 x 24.

Choosing the right dimensions is important for two reasons. First, considering the direction and design you might want to see in the tank. Will it fit your whole theme, will it highlight the theme’s strengths? Second is the placement. The right variation of the 20 gallon tank will have you setting your worries aside, in terms of safety and stability of the tank.

Choosing The Right Placement

The dimensions of the tank are directly related to its placement. No one would want a tank to be a hindrance in a certain spot, not with the fragile parts and materials that the tanks come with. The 20 gallon tank shines in this area because of the delicate balance it presents, it is big enough to store multiple fishes and more ambitious set-ups, but yet small enough to not cause a massive placement problem.

The 20 gallon tank is a beautiful addition in any room, and it provides a certain kind of therapeutic view for everyone who chances upon it. As a longtime tank enthusiast, I have found that one of the most important factors to consider is the stand that holds the tank.

With quite a large amount of water in it, aside from the weight that is brought about by the materials, it is made of, alongside the fishes and the décor, the 20 gallon tank will prove to need a sturdier stand than those used for 15 gallon tanks.

While it will surely take up a small space in any room, it will not pose much a problem than the bigger tanks. Just make sure that it is placed on a spot where the set-up’s needed amount of heat, cold, and exposure is met.

Choosing The Right Materials

There are a number of pros and cons when it comes to choosing the perfect material when choosing your 20 gallon tank, and they are not to be overlooked.

The traditional 20 gallon tank is made of glass. Hobbyists from all over the world have known this variation for the longest time. It is durable, as it is not much affected by scratches. Its sturdy material results in less yellowing in the long run, however, it is also quite heavy and will be in need of reliable support.

There is also the acrylic 20 gallon tank, which has become more and more popular as time went by. The acrylic 20 gallon tank is visibly clearer and quite easy to clean. It is also easy to move around because of its lighter weight. However, it does not have the same scratch resistance as provided by the glass tank.

Both are safe for the tank and your little fishies, and both have decorations and equipment that supports the material the aquarium is made of. Choosing the best one for you relies on the placing spot you have, as well as the aesthetic visuals that you are planning for.

Ultimately, it relies on what kind of direction you would want to take in. Because of its size, its versatility can be seen in the set-up it creates, be it a community tank, a breeding tank, or even a hospital tank. Be sure to have a clear picture of your plans in your mind as you choose the right 20 gallon tank variation.

The Right Price For You

After evaluating every factor from dimensions, placing, and the material, it is now time to think about the price. One great aspect of the 20 gallon tank is that it is an affordable tank, due to its popularity and size. The glass tanks are generally cheaper than its acrylic counterparts, but only in a smaller margin, unlike in the bigger tanks where variation costs may vary vastly.

As most of the 20 gallon tanks are sold as a package, complete with the lighting equipment, alongside the filters, heaters, coolers, and substrate, it can be a lot cheaper than other average-sized tanks. It also helps that it makes for an easier set-up process since all the equipment is already compatible with the tank’s material.

Choosing the right price also relies on another factor: the warranty. The existence of a product warranty is a show of the brand’s guarantee, and it can affect the pricing of the product itself. Will you opt for a one-time, cheaper buy for your tank or will you want to secure it for the long term? These are questions you should ask yourself before choosing the right tank for you.

The 20 gallon tank is also quite famous for the storage space it provides. Being a tank of the average size, those who are transitioning from nano fish tanks can observe the looseness that comes with the tanks from the average range.

  • Glass tanks. Glass tanks are the traditional material of aquariums. In addition, it is more expensive as compared to acrylic tank because it is more durable and can tolerate the pressure that 20 gallons of water exert. However, it can also get heavier as the glass gets thicker. But the good thing about glass tanks is that it will remain clear even after a very long time.
  • Acrylic tanks. If you want to keep fish but you are worried about your budget, acrylic tanks are the ones that you should aspire to have since it is cheaper compared to glass tanks. It is made of thin, lightweight, and clear plastic. However, it can turn yellow and opaque after a long time.

How to set up and use?

Like any other fish tank, the process of setting up the 20 gallon fish tank can be long and tiresome, but its importance overshadows the complexity and intricacies involved.

Water Prepping – Set aside the 20 gallons of water that you are to use for the tank. It is important to place them in a container and a place where it is less likely to be disturbed or contaminated. It is important to let the water sit for two (2) to three (3) days in order for it to settle, and also to let the unwanted chemicals dissolve away.

Deciding on the Direction – While waiting for the water to be ready, take this time to plan out your tank and the direction you want to take with it. Once you have started out in a direction, you cannot just change it willy nilly because setting up the tank is often for the long term, and the variable changes that might happen will have a tremendous effect on the whole tank.

Plan out the background and the general landscape theme you have in mind. It is also important by this time to choose the right substrate for your theme, and decide if you are planning to have additional elements to the tank, like live plants for example. This way you can leave a sort of allowance for the added elements.

After planning it out, you are now to place the substrate on the tank. Now the amount of substrate to be placed in the tank is entirely up to how thick you want it to be. However, the general ruling enthusiasts like to follow is 1lb of substrate for every gallon of water, which makes at least a 1” thick substrate for the tank. If you want it to be thicker, then you can opt for 2lbs of substrate for every gallon, which can make 2” of gravel bed.

Priming – After the waters sit out for 2 – 3 days, you can put it in the tank. However, to test out the waters, seasoned hobbyists would like to test out about half of the water and put it on the tank, along with the other decors and equipment. This is the time to install and test out the water filter, the air pump, the lighting, and prime them. After the installation and the priming, you can now place the decorations and complete the tank’s design.

Filling the Tank – Now comes the long part, filling the tank. While placing the water in the tank itself is fairly easy, letting it sit for a couple of weeks can be a grueling wait for some. However, patience is one of the key attributes of a fish tank collector, and as you will come to see as you grow in the hobby, it pays off in the long run.

Letting the water sit for a couple of weeks make sure that unwanted chemicals in the water will dissolve, in turn making the water ready for supporting marine life. The process also ensures that the water is ready to break down the wastes that will come with the live elements of the tank, like the fishes, live plants, and invertebrates. This process is helped along by the biological media of your filter, as well as the placement of live plants.

How to care and clean?

If you have a good filtration system, chances are you wouldn’t have to clean your aquarium as often. Cleaning up a tank should be done every two to four weeks, depending on your filtration system’s effectivity. Don’t wait for your fish tank to cloud with waste before you clean it. Set a regular schedule.

The following are the steps to cleaning your tank:

  1. Turn off all the equipment and remove them carefully.
  2. Fill a container with some water from the tank. This is where you will place your fish while you clean the tank, so make sure there is enough water for them to swim around.
  3. Carefully move the fish to your temporary container.
  4. Remove most of the aquarium water.
  5. Remove the tank accessories. It’s up to you if you want to remove the gravel too.
  6. Scrub the sides of the tank to remove waste and algae buildup.
  7. Run water through the tank to rinse the dirt away.
  8. Place your dechlorinated water into the tank. Don’t fill it up to the brim as you still need to place the original aquarium water and fish in the tank.
  9. Put the fish and the aquarium equipment back.
