Do you love fishes? Have you made your mind to own a nano aquarium for your desktop and office?
Well, we feel you!
A nano aquarium is a very small fish tank. It has all the functions of a normal sized aquarium, but simply adds a more minimalist style to the decor. If you are going to buy a nano aquarium, then you will have to know which will be most convenient.
In here, we will have a closer look at various aspects of nano aquariums. Further, we will also review the best nano aquariums that are available with us.
My Pick - The nano aquarium you choose will depend upon your preferences and the kind of features you are looking for in a fish tank. However, I would suggest you consider any one of the Fluval Models.
Now, there is no specific size for a nano aquarium; it is simply smaller than the usual aquariums available. Usually, a nano reef tank has the capacity to hold about 30 gallons of water, while a nano saltwater aquarium holds 15 gallons of water and this is because the normal size of these particular aquariums is quite large. However, many consider tabletop aquariums as well as small saltwater fish tanks to be nano aquariums.

Are Nano Aquariums Ideal For You?
Nano aquariums are ideal for those who wish to keep fish but do not want to undertake the hassle of maintaining a large tank.

That said, here we have shortlisted the best nano aquariums for you to make the right decision.

Designed to keep fish in freshwater, this nano aquarium has an all-in-one form factor which allows it to fit in any space. There are two sizes in which the aquarium is available: 9 gallons and 15 gallons.
The aquarium is made of high clarity curved glass and has a triple-layered filtration system. The filtration system has a foam filter to trap any unwanted particles like debris, excess amount of fish food or even bits of algae.
The second layer of filtration comes from an activated carbon pouch which removes organic materials dissolved in the water. Finally, there is a section for biofiltration.
This layer gets rid of ammonia and nitrites which are extremely harmful and can cause severe stress in fish, leading to several diseases.
There is a water pump fitted inside the tank. This water pump regulates the water and passes it through the layers of filtration.
The aquarium also has internal LED lighting with lights of different colours. These lights and their timings can be controlled with a Flexpad remote control.

Marineland Aquarium Kit

The cartridge has activated carbon and its molded ribbed back increases the contact between water and carbon. This gets rid of chemical impurities and odours.
There is also a bio-foam that is created to reduce organic particles and cultivate bacteria to destroy the harmful nitrites and ammonia components.
If the devices like the filter pump and water pumps make your tank look tacky, this one will help you find a solution. The nano fish tank comes with a three side open frame.
Behind the fourth side is the filtration and water pumping process done. The fish tank does not have any devices to entice the beauty of a natural habitat. The LED lights have different modes with both shiny and soft glows for day and night. The lights are hung from above with railing. This fish tank can hold up to 5 gallons of water and allows space enough for decorations, plants or gravel too.
