Best 5 Gallon Fish Tank Reviews 2020
1. Marineland ML90609 Portrait Aquarium Kit
Not all tank filters are created equal. See for instance, the Marineland ML90609 Portrait Aquarium Kit. This is the kind of filter that all hobbyists – whether a beginner or a seasoned one should have.
What I admire about this five gallon fish tank with filter kit is its size. It’s so small and compact it fits any small space. This is very ideal in offices and living rooms. It is also ideal for aquariums that can be put on top of a small desk. I even put one in my kids’ rooms, and they’re so delighted to see Betta fish every night before they go to bed.
In terms of performance, the filter in this aquarium kit works magnificently. The three-stage filtration system effectively keeps all the unwanted elements out of the water – particles, chemicals, and harmful organisms that could compromise the health of the fish and plants. Even though the filter is particularly small, it keeps the water crystal clear and totally smell-free at all times.
There are so many things to like about this product; like the fact that it is easy to assemble. I didn’t need to use any special tools just to set its filter up. But I think the best part of this product is its lighting. It keeps the aquarium well-lit which becomes a charming part of the decoration, especially at night.
What I don’t appreciate about this 5 gallon aquarium kit is how the LED lighting looks gets dimmer over time. Just four months of using this filter in my home office aquarium and the LEDs are already getting darker. It can be easily replaced though.
If you are searching for a five gallon aquarium kit that can be set up immediately, the Koller Products Panaview 5 gallon Aquarium Kit is the perfect product for you. Despite its small size, it delivers a top notch performance that’s not easy find in the market today.
There are so many things that I positively like about this aquarium. First is its price. It is cost-effective and can be easily afforded by entry-level hobbyists. For those seasoned ones who are looking forward to save some cash, this is an ideal product to purchase.
Next is the convenience. Installing the filter that comes with the aquarium is pretty easy to do, and you won’t need special tools. Even though its size is small, the filter has a powerful impeller. It can quickly clean a rather dirty tank water and keep it clear and smell-free for a long time. Its three-stage filtration system is totally impressive. It keeps unwanted particles, chemicals, and harmful organisms from spoiling the quality of water which can lead to the decline of fish and plants’ health inside the tank.
However, the filter of this tank can get really noisy. In all honesty, I did not expect this filter to be this loud. I placed it on my veranda where the filter’s noise is continually drowned by passing cars. But despite this one unfortunate setback, it still performs quite admirably.
3. Fluval Spec V Aquarium Kit
If you are a complete amateur in fishkeeping, chances are you are looking for 5 gallon tank fish combinations that would fit your level of expertise. The Fluval Spec V Aquarium Kit is definitely the one that will help your fish thrive even with minimal supervision.
There are so many things to like about this product. First is the design. I was very impressed that the filter itself is incorporated in the tank. Not all filters can be integrated in the tank itself. This one, however, makes things a whole lot easier. The filter is separated into a small compartment which allows the fish to roam freely without getting interrupted, although the filter looks a bit bulky.
I also commend the wonderful display of LED lights, especially at night. This feature brings out the beauty of the aquarium to a whole new level. I can easily see the condition of the contents of the tank because of the balanced illumination LEDs bring.
Seeing the design of the filter makes me agree on the manufacturers’ brilliant marketing strategy. The filter fits perfectly in the tank, therefore reducing any potential drawbacks that other separate products have. Moreover, the filter and the tank are absolutely durable and can withstand accidental bumps without getting compromised.
What I don’t like about this product is the uncontrollable flow rate. The flow rate is too strong for my fish. Sometimes I see them getting blown over when they pass through the portion of the aquarium where the water is delivered back to the tank.
4. Marina LED Aquarium Kit
Every beginning hobbyist needs a reliable and affordable aquarium kit. This way, they can slowly learn the process of maintaining their tanks and the contents thereof. If you know someone who is interested in keeping fish as a pet, the best filter that can help them succeed is the Marina LED Aquarium Kit.
What I like about this product is its reliability. I was surprised to see that it performs in a comparable level to other larger aquarium kits. Its three-stage filtration system keeps the water free from floating particles, undesirable chemicals, and harmful organisms which can prevent the fish and plants from thriving.
I also admire the LED which lights the canopy of the aquarium. I love how it illuminates the plants and the fish through the crystal-clear water. In my opinion, this is truly a marvelous addition to the product that can help other people appreciate the beauty of the aquarium. If I can have it my way, I want all of the filters to have LED lights to bring out the charm of my other tanks.
The best thing about this kit is the inclusion of fish food and the Nutrafin Aqua Plus water conditioner in the package. I highly doubt that other brands offer the same features. This is perfect for those who are just beginning to understand the meticulous nature of fish keeping. When I gave this aquarium kit for my 12-year-old son, he was thrilled to see the fish food and gave his Betta fish straight away. Of course I had to teach him how to properly feed the fish, it just shows how great this kit is even for kids. It’s a cool 5 gallon fish tank set.
What I don’t like about this product is the way it vibrates loudly, especially at night. My son complained about it and had to shut the filter down immediately. He thought that the filter should only be turned on during the daytime. After a nice conversation about this matter, he learned that the filter should not be turned off except during maintenance breaks. We disassembled the filter and reassembled it a few times, until the vibration was eventually reduced and the noise became tolerable enough for sleep.
5. Tetra Crescent Acrylic Aquarium Kit
Novice fishkeepers should have a reliable aquarium kit to help them maintain the health of their fish. If you want to keep your pet fish and plants alive, the best product that can help you is the Tetra Crescent Acrylic Aquarium Kit.
What I appreciate about this product is its portability. Every important component of the filter is packed together in such as small space in order to bring out the highest quality of water for the fish. The filter works as if it was intended for larger tanks. Moreover, it can be easily set up without using special tools. This is perfect for busy hobbyists.
The lighting is another commendable feature of this product. The effect of the LED on the aquarium is so mesmerizing I can’t divert my gaze on the aquarium to anything else. This is great for those who use their aquariums to relax.
The filtration system is also wonderful. Once started, the filter will make sure that no unwanted particles or harmful chemicals will linger on the water. For beginning hobbyists who wants to save every penny, this filter will make sure that the fish and plants will survive and thrive inside your precious tank and won’t easily die off. Finally, I love how this filter works quietly. This can be a phenomenal decoration piece in a classroom, library, or bedroom.
If there’s anything that I did not really like about this 5 gallon fish tank setup is its bulkiness. The size of the filter makes it difficult for fish to swim around and explore every nook and cranny of the aquarium. I just wish that they reduce its size so that the fish have some freedom to move around.
6. Penn Plax Curved Corner Glass Aquarium Kit
When it comes to performance, nothing beats the Penn Plax Curved Corner Glass Aquarium Kit. Whether you’re a pro or a complete novice, this product is absolutely perfect for you.
Complete beginners will absolutely love this aquarium kit. The package comes with a 5 gallon aquarium and its own filter. The filter is easy to set up; just plug it in and it is ready to go. Because the filter is so compact, it doesn’t obstruct the view. I can properly see the movements of my fish. Furthermore, the filter works quietly. This makes it an ideal decoration inside a bedroom, classroom or a library.
The aquarium’s rounded front corners are perfect for small kids. This way, they won’t cut themselves when they accidentally bumped their head into the tank’s corner. Moreover, the LED lamp provides an excellent illumination, especially at night. This allows me to properly check on the condition of the fish and plants without straining my eyes.
In terms of performance, the filter of this aquarium kit is truly amazing. It has a three-stage filtration system which keeps the water in pristine condition 24/7. It keeps unwanted particles, harmful chemicals, and unwelcome organisms which can lead to water’s discoloration and foul odor. I think that you won’t believe this filter’s magnificent performance unless you have one for yourself.
What I really hate about this particular product is the lighting fixture. Sure, it is bright, relaxing even. However, after only a few months, it becomes completely useless. I thought that the light bulb needs a replacement. But after examining it, I found out that it was the electrical connection that got compromised.
7. Glofish Aquarium Tank Kit
If you are looking for a good aquarium kit that would hide the fact that you are a complete beginner in fishkeeping, the best product that you can use in your newfound hobby is the Glofish Aquarium Tank Kits with LED Lighting.
One of the best things about this product is it comes with a 5 gallon tank. If you are a complete novice, you will find the feature quite beneficial because then you won’t have to purchase it separately. The curved shape of the tank appeals to sensitive aesthetics.
The lighting feature of this aquarium kit is truly elegant. It has 15 blue LED lights which not only provides illumination during night time, but also add an extra layer of beauty. The lighting works magnificently if placed in a dark corner of any room. I think that people who will see this lighting effect in an aquarium will make them get one for themselves thereafter.
Although this filter is designed for 5 gallon fish tank size, I believe that its filtration system is remarkable. It can successfully remove any standing debris or particles, harmful chemicals, and unwanted organisms to keep the water clean and odor-free at all times. Beginners will also love using this filter because it can really take some stress of fishkeeping away from them.
What I don’t appreciate about this product, though, is how the LEDs gradually destroys the ornaments inside the tank. The fish thrives with the LEDs on however, it’s the opposite when it comes with the plants. The upper portion of my ornamental plants that are near the LEDs withered. I can turn the lighting off but it would make the aquarium dull.
8. Fluval 10528A1 Evo V Marine Aquarium Kit
If there is a perfect product to help complete beginners to get started with fishkeeping hobby, this product is none other than Fluval 10528A1 Evo V Marine Aquarium Kit. This particular aquarium kit has features that both seasoned and novice hobbyists will surely appreciate.
The lighting system is absolutely terrific. With just one touch, I can turn on and turn off the LEDs. The lighting’s character is truly wonderful. I also realized that his can become a great decoration in any space I placed the aquarium on. What I was surprised to learn is how the LEDs are vital to coral growth. Apparently, the LEDs of this particular filter promotes the growth of said marine creature!
In terms of performance, the filter of this aquarium kit’s three-stage filtration system is really fantastic. It can easily clean the water without getting strained. Moreover, the water doesn’t get any bad smell after every kind of fish food I put there. I think that novices will appreciate how powerful its filtration system is.
Other positive features of this product is its durability. I am happy to report that after almost five months of using this in one of my 5 gallon tanks, it is still in top condition. This is something that beginners will appreciate because they won’t have to replace their whole aquarium kit soon.
If there is one thing that I don’t approve of this product is how tight it looks from a distance. The honeycomb cover may be doing a good job hiding the filter away but in reality, it makes the aquarium look uncomfortably compressed. I feel like the fish doesn’t have enough space to move around.
9. MarineLand Nook Aquarium Kit
If you want a serious aquarium kit to help you get started on your newfound hobby, one of the best products that you should try using is the MarineLand Nook Aquarium Kit.
Personally, one of the best features of this aquarium kit is the wide front. This gives the illusion that the tank is huge. Moreover, it is very fun to see the fish swimming around because it provides a visual effect that the fish are large.
The LEDs not only provide illumination but also a fantastic effect on the tank. Once the lights are turned on, there is a whole new level of beauty that can be viewed on the aquarium. This is what made fall in love with this particular product. It really became an integral part of my home office’s decoration.
On the other hand, the filter’s three-stage filtration system gives the water crystal-clear quality. Through its mechanical filtration, no amount of debris or particles are left on the water. The biological filter removes harmful organisms which can affect the health of the fish and plants inside the tank. Finally, the chemical filter prevents the water from getting discoloration and bad smell.
I have observed that this filter is easy to set up and maintain. This is beneficial to me because I am a very busy person. This way, I don’t need to focus a significant portion of my time just to maintain the filter. I think amateurs will also love this feature as it will not take too much of their time and effort.
Make no mistake; this aquarium kit is great, but it has some flaws. What I don’t appreciate about this product is the tank is actually too small for diverse plants and fish. I also feel like they are too cramped inside.
10. Carolina Biological Supply Company Aquarium Tank
Sometimes, you don’t need a filter to ensure your pet fish’s survival. All you need is a good aquarium to launch a successful career in fishkeeping. Or maybe you want the option to purchase a separate filter yourself. For such purposes, the Aquarium Tank, Glass, 5-1/2 Gal by Carolina Biological Supply Company would be good for you.
If you want to go back to basics, this is the aquarium that you should be looking for. This 5 ½ gallon tank is made of triple-strength glass that is protected by a silicone rubber. This makes that tank able to hold the water without straining and eventually breaking.
The thickness of the glass is just enough to accommodate the weight of the filter it is going to use. In addition, no amount of seawater can decrease the integrity of this aquarium. This makes it a very ideal tank for marine fish and plants.
If there is one drawback with this product, it’s that it is not a 5 gallon fish tank with filter and heater. But as I mentioned above, you can simply purchase one on your own additional aquarium equipment.
What To Look For When Buying A 5 Gallon Fish Tank
For first time fishkeeping hobbyists, buying their first aquarium may feel like a very daunting task. This is because they are not armed with enough information which could help them choose the right 5 gallon fish tank that could help them understand the delicate yet exciting field of fishkeeping.
Here are the things that you should be looking for when shopping for a 5 gallon fish tank:
Durability. When purchasing aquarium kits, the first quality that you should look for is durability. This will definitely save you money down the road. The tank must be able to withstand the pressure that the water constantly exerts. If the glass is frail, the water will easily leaks through the cracks, causing unfortunate incidents. Also, make sure that the silicone sealings are completely watertight to prevent accidents.
Ease of set up. Amateur hobbyists need an aquarium kit that are easy to set up, otherwise they will lose interest midway. Make sure that the product that you are buying are absolutely easy to set up
Ease of maintenance. Regular maintenance is the key to longevity of any item. This also applies to aquarium kits. However, if the aquarium is not easy to maintain, it will meet serious damage during cleaning. Make sure that the aquarium is light enough to be moved and turned around to avoid any accidents during maintenance sessions.
Aesthetically pleasing. Who would want an ugly glass box to put their precious fish inside? No one, actually. A beautiful aquarium, no matter the size, adds elegance to any space inside (and even outside) the house. So when purchasing aquarium kits, make sure that it has the exquisite appeal that the space where it will be placed radiates.
Price. Price is always the greatest deciding factor when shopping for any item or product. If you feel that you only need the aquarium kit to gain experience about fishkeeping, it is highly suggested that you choose the affordable ones. However, if you have the budget and you wish to impress your friends, family, and loved ones, then you can choose the ones that will suit your extravagant taste.
Components included (for Aquarium Kits). Not all aquarium kits are priced the same. This is due to the fact that not all brands use the same materials and design. There are some aquarium kits that use simple design which targets completely entry-level enthusiasts. On the other hand, there are some aquarium kits that have over the top features such as filter cover, cellphone-controlled LEDs, LED hood, among others. These features will determine the price of the aquarium kit that you are setting your sights on.
If you think that you only need a modest aquarium, you can always the affordable ones. However, if you are about integrating the aquarium to the overall design of your home, office, or any space you think of, then you can always choose the technologically-advanced ones.
Choosing the best 5 gallon aquarium is actually not easy. There are many factors that will come into play which will decide your choice. By considering the factors mentioned above, you will not have a hard time picking the aquarium kits that will help you succeed in your fishkeeping endeavor.
Other Important Factors To Consider
What is a 5 Gallon Fish Tank?
The 5 gallon fish tank is a great entry level aquarium. It compact size means it would not take up much space, which is great for those who can only spare a little room but wants the therapeutic visuals that only a beautiful fish tank can give. With a 5 gallon tank, you can create a unique world for your little fish friends, and without the hassle of placing!
As an enthusiast for many years, I myself dove into this hype and started collecting 5 gallon tanks for quite some time now. What makes it so irresistible is its size and its affordable price. With that combination, you can collect fishes in different set-ups and variations; the possibilities are just endless! This is precisely the reason why it is especially celebrated in the community of nano fish tank hobbyists, with such potential for saltwater and freshwater collecting in its small body!
How Does it Work?
Just like any other tanks, setting up the 5 gallon fish tank is painstakingly meticulous (with a tiny splash of complexity), but it is all worth the time, effort, and energy. How your little fish live in this new environment is dependent on how great your set-up is. This requires focus and patience, attributes that tank owners should have.
- Prepping the Water
This is the first part of setting up your fish tank. Take five (5) gallons of water, and carefully place them on a basin or container. They could be in one container or separated, what matters is that it sits undisturbed for a couple of days. Careful not to contaminate it, or you will need to repeat the process.
- Deciding on the Décor
While waiting for your water to settle in, you should decide on the décor of your tank. Look for the right substrate and background that is to your liking. This is also where you decide if you want a fish-only tank or a planted tank. The overall design of your tank depends on what tank you are making, because of all the adjustments and allowances that you are specifically placing.
- Priming and Equipment Set-Up
After a couple of days waiting, you are then to put half of the water inside the tank. After this, you are now entering the equipment phase. This is where you put in all the extra equipment for your tank. The tank filter, the air pump, the heater, and the light. Putting in the tank filter, there is a process called ‘priming’. This is where you place water inside the filter and let it run for a while. This is to assure that there are no air bubbles or air pockets inside the filter’s tubes, which can cause it to overheat and malfunction later on. Once the priming and testing is done, this is when you can add live plants to the tank.
- Filling the Tank
After priming and setting up, you will now fill the tank with the rest of the water you kept aside. You will then let it sit there for at least two weeks. This might be a long time for a beginner, but for seasoned hobbyists this is just natural. This is done to ensure that the chemicals in the water that are unnecessary for the fish environment you are setting up will dissolve. This is done to ensure that the water is conducive for your little fish friends, and that the water is ready to detoxify and break down fish waste. The trick to speeding up this process is to enlist the help of live plants and placing a filter media that supports biological filtration.
What are the Different Types of 5 Gallon Fish Tanks?
The 5 gallon fish tank is famous for two known tank types: the fish-only tank and the planted tank.
With its small body, the 5 gallon fish tank is a great fish-only tank. The general rule of thumb is that you are to add only 1 inch of fish per gallon. Basically, if you have a fish that grows to an inch, the maximum number of fish in your tank should be five (5). Now, budding enthusiasts might think that this leaves you with only a few options, however, you would be surprised to know that you actually have a number of options out there. From the cute Dwarf Puppers to the tiny Least Killifish, to the beautifully exotic Siamese Fighter Fish, the options are amazing!
Aside from being a fish-only tank, the 5 gallon fish tank is also a great planted tank. With numerous sets designs and equipment fitted for setting up a tiny, wonderful world inside your 5 gallon tank, the design possibilities are endless! Just remember that in a 5 gallon fish tank, scaling matters. Some designs will make your fishes pop, some will have them blend, it is up to you to decide on the aesthetic direction you will undertake!
For a number of hobbyists, the adaptability and space that the 5 gallon tank gives can mean different uses.
- As a Breeding Tank
The 5 gallon tank can be a great breeding ground for a variety of small fishes. If you think that it is safer for your fish to breed privately and away from the distractions and threats that other fish might pose, then keeping a 5 gallon tank as a breeding tank can be beneficial.
- As a Species Tank
Some fish can only survive under strict and complex conditions. This can be about the temperature, the water itself, the need for an unusual habitat. This could also be about their behavior, if they are predatory, aggressive, territorial, delicate, or they might have specialized behaviors with regards to feeding. If your fish require a special habitat built just for them, a 5 gallon fish tank might be handy for you.
Why Do You Need a 5 Gallon Aquarium?
All in all, the need for a 5 gallon fish tank varies as discussed. A lot of elements and factors should be taken into consideration in stocking a 5 gallon tank. However, if I am to sum up why the need for the 5 gallon tank exists, it is because this tank is affordable, a space saver, and a gateway to multiple uses.
If you are looking to start collecting fish tanks, or you want to add a 5 gallon fish tank to your collection, then keep these factors to consider in mind and be headed on your way!
Frequently Asked Questions
What are the most trusted 5 gallon aquarium brands?
There are several aquarium brands available today, but there are several more preferable ones of course. These are:
- Koller Products
- Penn Plax
Most of these products I have tested and mentioned above.
How big is a 5-gallon fish tank?
The typical fish tank has a length of 16 to 18 inches, a width of 5 to 8 inches, and a height of 10 inches. However, some makers like to innovate by creating cube ones, vertical ones (tall and narrow), even curved ones. So the size depends on the style. But it’s the smallest filtered aquarium that can fit on your side desk.
What fish can live in a 5-gallon tank?
There are several types of good fish for 5 gallon tank. Full-grown fishes that are small to medium in size (1 – 5 inches long) can fit and live in this small tank. I have my bettas for this, but you would also often see paradise fish, clownfish, killifish, puffer, gourami, crayfish, loach, livebearer, gourami, or fighting fish in some other 5-gallon tanks.
How many fish can I put in a 5-gallon tank?
Again, the rule of thumb is one inch of fish for every gallon of water. So depending on the size of your fish, you’ll have: 5 one-inch ones, or 2 two-inch ones plus 1 one-inch fish, or 1 five-inch fully grown fish for your 5-gallon tank. This may seem an easy ratio, but you also must account for the total allowable space for the fish to grow.
Try to estimate first all the dimensions of the materials (e.g. ornaments, filters, pumps, etc.) that you will set up inside the tank. Once you have an idea of what you’ll put in, you may deduct the space that these will occupy to the total capacity. From there, you may know the number of fish you can put so as not to make the aquarium too crowded.
Fish may be harmed by their wastes, too. Since they too have by-products, it is important to take note of the frequency and amount. The wastes should be easily cleaned by the filters and should not stay long in the water. So, try to put one or two fishes first, then add the other fishes once you’re sure the unwanted products can be cleaned properly.
What fish tank equipment do I need for my 5-gallon aquarium?
There are things that I wish I had known before I decided to keep fishes as pets. I should have not bought a lot of unnecessary things for the aquarium. Here’s a list of the important equipment and materials:
- Filtration system – Choose one that is reasonably priced and can support your fishes’ needs
- Stand or Table – A support for your aquarium is a must.
- Fishnet or mesh – You can use this as cover.
- Siphon – I use this whenever there’s a need to adjust the volume of water or when I had to get something that is deep down the aquarium.
- Scrubber – This one’s to clean the built-up algae around the tank.
- Thermometer – If you are planning to breed them or if you have a fish that is sensitive to temperature, a thermometer can come in handy.
- Heater – This is useful mostly during winter.
- Light – this helps illuminate the aquarium at night.
There are some other things that you might put in the tank and buy, but they’re not really equipment. You can add gravel, plants, water conditioner, and even figurines.
How to setup and use?
It really depends on the aquarium you opt to buy. If you purchase an aquarium kit, make sure to follow instructions included in the kit. Setting up is pretty standard though:
- Clean the aquarium first
- Prepare the water for at least 12 hours
- Prime the equipment (filters and pumps) by running water through it
- Fill the tank with the prepped water
- Decorate the tank
- Add the fish!
How to care and clean?
There are two ways to maintain and clean a five gallon aquarium: with weekly water change, and deep cleaning for every two to three weeks.
Weekly water change
Tank owners are expected to remove some of the dirty water and replace it with the same amount of clean water. You can remove 25% to 50% of the dirty water. Make sure you prep the clean water first by making it stand for 12 to 48 hours.
This must be done every two to four weeks. This is important so as to prevent algae and waste build-up that will not only be unpleasant to look at, but also toxic for the fish. Some algae is alright, but too much of it can also be bad.
The steps to do a deep cleaning are as follows:
- Get some of the original aquarium water and place it in a container which will temporarily house the fishes. About 30% of aquarium water is fine.
- Turn the filter off and remove it, then carefully remove tall decorations so as not to stir the water too much and to prevent stressing the fish.
- If you’re using a pump, move it to the temporary container. Carefully remove the fish and place them on their temporary home while you clean the aquarium.
- While the tank still has water, scrub the sides to remove some of the algae and waste buildup. If you like to leave some algae, that is fine. Make sure that it does not overtake the tank, though.
- Siphon the old water out.
- Vacuum the gravel.
- Fill the tank with clean water that has been prepped for 12 to 48 hours. Don’t fill it to the brim as you will place the fish back together with the old aquarium water. This is so as not to stun the fish and help them adjust to the new clean water better.
- Alternatively, if you don’t have time to prep the water for at least 12 hours, use a water conditioner. A water conditioner neutralizes chemicals in the water.
- Replace the decorations, pump and filter.
- Reintroduce the fish by pouring the contents of the temporary container to the aquarium so you place the remaining old aquarium water back.
Don’t wait for your tank to see visible signs of dirt before doing a deep cleaning. Instead, create a schedule between two to four weeks, else you’ll pay for it by having unhealthy, or even dead, swimmers.
Having an aquarium is like adding something beautiful and peaceful to your place. If you want to relax and declutter your mind, just look at your fish tank and you’re set. Even the smallest tank will do – a five gallon one. Since it will be an important part of your lifestyle, you should choose nothing but the best 5 gallon fish tank.
