When it comes to buying a small aquarium there’s a lot of things to consider including the site, litres and type of tank you’d like to have. Planning the tank at the early stages will give you a much better finished tank. The buying process should start with an idea of what you want to put in the tank and how it will look rather than buying a tank. Having a vision for a small (commonly referred to as Nano) tank means you can achieve a beautiful tank in no time at all.
Best small aquariums – buyers guide
Firstly consider the space you’re going to put the tank in. The best place is away from direct sunlight – So not on a windowsill as it will turn green with algae in no time. Some small aquariums come with a stand that matches so can be placed where ever its convenient. The second thing to think of is whether to have a cold water, tropical or marine nano tank. We will cover these options in the next few sections –
Tropical nano tanks
I’m a big fan of tropical nano tanks and have a couple myself around the house. They’re a very underused idea for brightening up a dark corner and adding some interest to the room. Well planted tanks can be visually beautiful with vibrant coloured plants and fish creating a real under water abyss. There’s no need to think just because the tank is small that it cannot be impressive – some of the best looking tanks are the small but well thought out tanks.
Featured – Fluval Flex
With slick curved designs and all the filter media nicely tucked away the Fluval flex is our recommended small tank of the month. You can see out full Flex review here. It comes in a choice of 2 sizes and is a great option if you’re looking for a starter aquarium.
Featured – Tropical tank – Interpet 19L
This is a lovely small tank at just 19L and is recommended as our best small aquarium for beginners. It’s small enough to be easy to manage yet big enough to create a nice under water scene. There are some 10 litre aquariums available but we’re not keen on these as they are a little to small to manage with fish and shrimp growth.
The interpret nano tank has the filter built in the back so it keeps the cables hidden away. It has nice curved edges and a light that sits above the tank – this means your not always cleaning the led strip like on some tanks. You can buy this tank on Amazon in the UK, check the latest price via the button below (will take you straight to the right tank too).
This small tank looks its best with a natural planted look which will also make it easier to keep clean. We have a guide to setting up a small planted tank we made here (also known as an aqua scape).
As well as the tank you’ll need the heater for tropical fish, but that’s all for getting it setup. If your planning a planted tank you’ll also need a good quality sub-trait to help the plants grow. Here’s some ideas of how they can look
As for fish it’s a small aquarium so small fish are best along with shrimp. Shrimp are excellent for keeping your tank clean and making it easier for you to run. Recommended small fish for this size tank would mainly be rasboras and as shown below they are beautiful fish that brighten up the tank.

Small tanks buyers guide – Things to consider
- Where is the tank going to go – it should be away from direct sunlight and head sources – avoid putting it by a radiator.
- Do you need a cabinet or will it go on an existing surface, if so does it need protecting – some aquariums come with a mat to place them on like the Flex mentioned above.
- What size tank do you want, we cover small tanks from 22L to 70L and find for a starter tank around 35L is a good size – enough to get a nice design and some decent fish without being too big to manage. This also work well as a separate incubator tank for baby fish.
- Think about your current style of furniture and where it will go – Will an ultra modern tank suit the space its going in. For us a nice fish tank should enhance its surroundings and draw you too it rather than standing out and looking odd or out of place. (There is a place for the ultra modern fish tank).
- How much maintenance do you want to do on your small aquarium? A tropical setup is easier to keep but small reef tanks can also look stunning with a little more work. Nothing looks worse in a fish tank than it being covered in green algae as you don’t have time to look at it.
Aquascaping in a small aquarium – ideas
Here’s our very popular Fluval Flex 2 stone setup with river from our You Tube channel
Aquascaping is the name for designing a planted aquarium – Easily put its the same as landscaping your garden but on a smaller scale under water. With the right planting and planning even the smallest fish tanks can be a thing of true beauty. If you’re planning a starter or nano tank then here’s some tanks we like that are a good use for inspiring your tank (please note these are not our tanks and where possible we link the image back to the owners blog – if you see one we’ve missed linking just let us know).
This is one off my personal favourites, it’s leading on the eye with the over hang and just looks perfect. If I find the right stone I’d recreate this in one of my own tanks to see if I could get it as good. There is just something magical about this tank that I love.
I like this one for different reasons – the natural effect of the tree makes it look like an above water scene under water. This is very tricky to pull off and would take a lot of maintenance to keep the tree from over growing.
I’ll soon be starting a nano reef project and this will be my inspiration. It’s the absolute best nano reef aquarium I’ve ever seen, the colour of the coral is dazzling even without any fish in it. I’d be proud to have this tank in my home – hopefully I’ll have something similar soon!
