Fish Tanks

Starting an aquarium doesn't have to be a difficult task. At Swell UK we stock a range of fish tanks and so whether you're looking to start your own tropical aquarium, coral reef or just a standard cold water tank, you can find the ideal tank right here.

When putting an aquarium together, it's important to remember to include a aquarium filter, air pump and if you're going tropical, an aquarium heater. Once you've purchased all the necessary equipment to keep your aquarium running smoothly, take a look at our substrate and aquarium decor to decorate your tank and give your fish plenty of places to explore. Read on below for more advice...


If you're thinking about buying an aquarium, you've come to the right place. Whether you're purchasing your very first fish tank or upgrading a current one, we have a wide selection of tanks to choose from. 

Before you select a tank, you need to have a think about whether you want a tropical, cold water or marine aquarium. Here's our guide to setting up a tropical aquarium.  Once you've decided between tropical, marine and fresh water, it's time to look at the tanks themselves! This may seem like a daunting experience, but we've put together a little guide to help you on your way. 

If you have a limited amount of space available in your home or office, you might want to consider a Nano tank or an aquarium that is less than 40cms in size.

These can be a perfect way to get started without letting your tank take over your home. It's worth remembering that not all fish are suited to small tanks and therefore Nano aquariums and those that are less than 40cm in size are best suited for shrimps or very small fish.

If you're after a small tank that allows excellent viewing, the Fluval Marina 360 fish tank could be the aquarium for you.The circular shape is fantastic if you want to see every little detail. It includes LED lighting and excellent filtration. If you're keen to keep tropical fish, then you'll need to include a small fish tank heater.

If you want a small aquarium that has a specially designed stand to support it, the Tetra AquaArt Aquarium kit might be for you. 

The AquaArt Aquarium Kit 30 is an attractive aquarium kit that is designed to offer everything you need to keep a beautiful aquarium without the stress of having to find all of the required parts at once. This set offers everything you need in one high quality kit. As well as the 30 litre aquarium this kit also includes an excellent lighting and filtration system, Tetra water conditioners, substrate and also two filtration cartridges.
