Best Nano Aquariums for Your Desktop & Office Reviewed

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 tank, 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.

Nano Aquariums

First Things First, What is a Nano Aquarium?


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.

Benefits

The Fluval Spec V however, remains a really good choice because of its design and its accessories. All Fluval models have great customer support so you need not worry about that.
  • Nano aquariums are affordable and the total set up cost along with any extra fittings is still less than a regular sized aquarium. This is because you will need fewer accessories and a small fish tank will consume much less power.
  • The maintenance of an aquarium is not an easy task, especially if it's a large one. Therefore, several nano aquariums will allow you to divide the load and will cost much less.
  • Nano aquariums obviously do not take up too much space, and therefore they are convenient for offices, desktops and studio apartments.
  • Nano aquariums are quite lightweight and they can easily be carried. This also means that such fish tanks can be placed on almost any surface without having to worry about causing any damage.
  • Maintaining a nano fish tank is much easier than maintaining a huge 125-gallon aquarium. Changing the water becomes easier too.

Drawbacks

While nano aquariums are quite convenient, their small size does cause them to have some disadvantages.
  • Due to its small size, you cannot keep too many fishes in it and you cannot even have a lot of aquatic plants or too many ornaments. If you decide to have more than one kind of fish, find out about their habits and if they are territorial. Also, research about the types of fishes that can be kept in a nano aquarium (for example, dwarf rasboras, pygmy sunfish, pygmy swordfish).
  • The maintenance of an aquarium is not an easy task, especially if it's a large one. Therefore, several nano aquariums will allow you to divide the load and will cost much less.
  • Accidents can end up being fatal. If your water heating stops working or the temperature changes, then the water of the whole tank will be affected in a few hours and you might end up finding dead fish.

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. This, however, does not mean that nano aquariums are only for amateurs because even they must be extra careful when it comes to handling such a tank, as one small error might cause the entire system to fail.

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