10 Best Desktop Aquarium

Fluval Hagen HG Flex Aquarium 57L, 15gal, Black

This is a freshwater aquarium, and due to its size, you can also call it a nano aquarium. And it has an all-in-one form factor that allows it to fit in any space but might be hard for small desks. It is a 15 gallons fish tank and just perfect for desktops.

The aquarium is made of high clarity curved glass, and the aquarium also has internal LED lighting with lights of different colours. You can control these lights and their timings with a remote control that comes with the kit.

It has a triple-layered filtration system that does a good job of keeping the water clean. The filtration system has a foam filter to trap unwanted particles like debris, excess amount of fish food or even bits of algae.

There is a section for biofiltration to eliminate ammonia and nitrites, which are extremely harmful and can cause severe stress in fish, leading to several diseases. A water pump fitted inside the tank regulates the water and passes it through the layers of filtration.

The filtration system is good but not long-lasting; as said by many people in the reviews, the filter pump stops working after one year and loses suction.

Buying Guides

You need to be careful while choosing an aquarium as there are so many factors that need to be taken into account in order for you to get the best desktop aquarium for your room or office desk.

Keep reading ahead, as Given below are some important points and information that will help in putting your money into the best choice:

Things to consider while selecting the best desktop aquarium

Choose equipped tanks

When you are planning on buying a desktop aquarium, it is always best to go with the option fitted with everything that an aquarium should have. 

Normally, average and large size aquarium kits come with every basic and extreme necessary feature already included. Still, even small aquarium kits are not lacking in providing the best living environment possible.

Make sure that your aquarium kit includes important features like a CO2 Regulator, a good and proper Aquarium Sponge Filters, internal tank decor, aquarium lights, etc. These are some important features for your tank to become the perfect home for your fish.

Even when comparing several desktop aquarium options, choose the one that has more features and facilities equipped with it. It is understandable that it’s impossible to keep all the features in a compact tank, but you don’t want to buy just an empty tank for your dear fish as well.

You can buy extra external pieces of equipment as per the suitable size of your aquarium, but that would need additional investment and also take a bit more space on your table. 

The available space  

It is always advisable that, before looking for any type of aquarium, be it a tiny one or a big bish tank, always measure the place where you are going to place it and the dimensions of the aquarium so that it will fit there perfectly.

The size and shape of your aquarium will depend on the area and space available on your desk or the place where you intend to keep your desktop aquarium. This makes it an important factor that you will have to consider when selecting an aquarium for your home or office.

If there is very limited space for the aquarium on your desk, you will have to go for aquariums that are compact and will be able to fit better into the given area. 

Size and shape of the Aquarium

Even aquarium tanks are available in different sizes, and shapes like some are cube, while some are square. We even get to see small circular shaped aquariums these days getting popular for giving an advanced look.

As we have already seen in the above section, “The size and shape of your aquarium will depend on the area and space that is available on your desk or the place where you intend to keep your desktop aquarium”.

I’ll help you to understand this better. If you want to have a fish tank for your betta and you want a 5 gallons aquarium but, there is space for only a 3-gallon aquarium on your desk.

Then you can consider buying a vertically elongated tank or a tank with height to increase the water holding capacity of the tank, and your cute little pet will get more area in its new home to swim around.

You can buy a horizontal rectangular tank if you have enough space. Some people also buy small cube tanks and small circular tanks as they look very cute and give a very nice and different look to your table decor.

Apart from the plain traditional aquariums, there are other aquariums with different and advanced designs that will just blow your mind with their beautiful look.

Filter size and power

Having a filter in your small aquarium is one of the most important features of a fish tank. This is because your fish keeps producing waste regularly, and as it’s a small tank, it is easy to get the waste to accumulate and decrease the water quality.

You might have to change the water and clean the tank regularly, and if not done properly and regularly, this could make your aquarium water and environment unfit for the survival of aquatic life.

When you are searching for small aquariums for your desktop, you may go through several filter options. Some aquariums may come with an inbuilt filtration system, some may come with a hang-on filter, and some may come with no filter with the aquarium kit.

For such options, you may need to buy separate filters. Make sure your filter is not too big to take too much space in the tank, as there will not be much space for your fish to swim.

If your tank does not have enough space to keep a submerged filter, then you can just buy one to keep it outside the tank. This might not be that attractive to look at, but at least your fish won’t die.

Avoid choosing filters that have strong suction power or produce strong streams, as this could be a huge problem for your aquatic pets, especially as it is a small fish tank. 

This is because all fishes are not fond of and are not used to living in strong water stream environment, only a few types of fishes can handle the strong water stream, and as it is a small fish tank, it is really easy for fishes to get caught up in the suction pump and water streams.

Go through reviews

When buying anything online, we always check for the reviews and comments of the people who already purchased the product and used it, and after going through it, we decide if we want to buy the product or not.

You have to do the same when searching for a desktop aquarium, go through the reviews and comments of the people, and you will know the important stuff of that aquarium if it works well or not or is worth buying.

This may sound a bit time consuming, but we have already done the hardest part for you with the list provided above. You can just compare the prices and features and select the best option for you.

If you have loads of free time in your hands, you can surf around more and compare the reviews and features for selecting the option that would top your list.

Cost of the Aquarium

It is true that a small fish tank cannot invite all the features that a large fish tank can, but still, some basic features that will keep your tank healthy are expectable.

When choosing a desktop aquarium, compare several options and go with the one that provides more features at a minimal cost. Before buying, you must go through the reviews to know if the parts are working properly or not at that price.  


There are so many things that you should consider before buying an aquarium tank. With the wide variety of options available in the market, it is extremely easy to get stuck and confused about which tank is best suited to be kept on your desk to become the home of your little pets. I hope that the reviewed list and the buying guide I provided helped you choose the best desktop aquarium.
