Our Favourite Nano Aquariums: Our Top 5 Picks
Think you need a huge aquarium to create a beautiful underwater world? Think again!
Nano tanks are a fantastic way to bring the beauty of the aquarium hobby into smaller spaces, whether you're a beginner looking for your first setup or an experienced aquarist wanting to add another tank to your collection.
From planted aquariums to specialist Betta and Shrimp setups, there’s a compact tank to suit every space and style.
What is a Nano Tank?
So, what exactly is a nano tank?
There isn't one universally agreed size that defines a nano aquarium, but generally, the term refers to smaller aquariums designed to house fish, shrimp and aquatic plants. They're compact enough to fit into smaller homes, offices and bedrooms, while still giving you plenty of scope to create an impressive aquascape.
Nano tanks can also be easier to fit into your lifestyle than a large aquarium. However, smaller tanks aren't necessarily easier to look after. Because there's less water volume, changes in water quality can happen more quickly, so regular maintenance and good filtration are particularly important.
What Fish Can Live in Nano Tanks?
Choosing the right livestock is one of the most important parts of setting up a nano aquarium.
Not every fish is suitable for a small tank. Always consider the adult size, swimming behaviour and space requirements of your chosen species rather than simply choosing fish because they're small.
Depending on the tank size and setup, suitable options can include Bettas, Shrimp or small species of fish such as:

|
|
|
|
|
|
|
|
|
|
|
|
|
|

These are just a few examples of the fish species that can be suitable for nano aquariums. If you have a particular species in mind, get in touch with us and we can advise whether it would be suitable for a nano tank. It’s also important to consider compatibility, as not all nano species will necessarily live peacefully together.
Nano aquariums can also be perfect for creating a dedicated shrimp-only setup. Watching a colony of shrimp explore plants, rocks and other hardscape can be fascinating, and they can make a beautiful addition to a smaller aquarium.
Whatever you choose to keep, always check the specific requirements of your chosen species before adding them to your aquarium. A successful aquarium isn’t just about creating a beautiful display; it’s about providing the right environment and enough space for its inhabitants to thrive.
We have a wide selection of fish available in store, with new arrivals and changing stock every week. Why not pop in and see what catches your eye? Our friendly team is always on hand to help and offer advice on our fish, their care requirements and which species are best suited to your aquarium.
Our Favourite Nano Tanks
Here are five of our favourite nano tanks, in no particular order…
1. Fluval Flex
Available in 34L and 57L, the Fluval Flex is a great choice if you want a modern aquarium with plenty of features packed into a compact design.
One of its biggest advantages is its powerful filtration system, helping to keep the aquarium water clean and healthy. The filtration and other equipment are cleverly hidden away, giving you a much cleaner view of your aquarium.
The updated design also gives the Flex a contemporary look, making it a great addition to any home. Want to find out more about this aquarium? [Click here] for an in-depth look at its features, specifications and everything it has to offer!
Why we love it: Powerful filtration, hidden equipment and a stylish but thoughtful design.
2. Fluval Betta Kit 20L
As the name suggests, the Fluval Betta Kit has been designed specifically with Betta fish in mind.
The 20L capacity provides a generous amount of space for a single Betta fish, while the design makes it particularly well suited to creating a planted aquarium. The hidden filter system keeps equipment discreet, allowing your plants and your Betta to take centre stage.
It also comes with a pre-set heater, making it a convenient option for anyone looking to create a tropical setup without having to source every piece of equipment separately.
Why we love it: Designed with Bettas in mind, great for planting and includes a pre-set heater.
3. Aquael Shrimp Smart 30L
If you're looking to create a beautiful, planted aquarium, the Shrimp Smart 30L is well worth considering.
It features a great light for plant growth, helping you create a lush and vibrant aquascape. A pre-set heater is also included, making it a convenient choice for a tropical setup.
And, of course, there's the design. Its sleek appearance makes it a tank that looks just as good sitting on your furniture as the aquascape inside it.
Why we love it: A sleek design, good plant-growing light and a pre-set heater.
4. Kubus 54L
At 54L, the Kubus is arguably on the larger side when it comes to nano tanks, but that's also part of its appeal.
Its modern, minimalist look makes it a fantastic centrepiece, while the footprint gives you plenty of possibilities when it comes to aquascaping.
Whether you want to create a carefully planned planted aquarium or simply give your fish plenty of room to swim around, the Kubus offers a great balance between compact size and usable space.
Why we love it: A modern design and a great footprint for aquascaping or giving fish extra swimming space.
5. Marina Lux
Looking for a stylish tank without spending a fortune? The Marina Lux is a fantastic budget-friendly option.
It's available in 19L, 38L and 75L, so there's an option for a range of spaces and stocking plans. And if you want something a little larger than a traditional nano tank, the 75L model gives you plenty of extra room.
We also love the design. It's a great-looking aquarium that doesn't feel like a compromise just because it's budget-friendly.
If you're setting it up for tropical fish, you'll just need to add a heater (this is not included in the smaller models).
Why we love it: Great value, lovely design and a choice of sizes; including a larger 75L option.
