Best Aquariums (Fish Tanks) in the UK

The Hagen Fluval Flex is one of the best aquariums for those who want to have a lot of fishes or even breed them in the future. Plus, it looks fairly stylish, so it will be a great fit for your living room or office.

This model has a pretty generous capacity of 54 litres and sizable dimensions of 41 x 39 x 39 centimetres. Thanks to that, you will be able to set up a perfect habitat for your pets with plants, rocks, houses, and other things so that they feel extra comfortable. But if you are limited in space, a smaller 34-litre option is also available.

What makes this aquarium better than most of its counterparts on our list is that it comes with a set of all the essential accessories, including filters and lighting. The filter boasts a 3-stage filtration system (mechanical, biological, and chemical) that ensures that your fishes will swim in the cleanest water. It includes a foam filter block, carbon, and BioMax inserts. Plus, the filter is easy to remove, so changing it won’t take you long. The lights can be adjusted to the needed colour and brightness with convenient remote control.

So, if you want your fish and plants to have a comfortable living space, we highly suggest going with this aquarium kit for beginners from Hagen. It offers good overall quality, large capacity, and a full set of useful accessories that justify the somewhat high price of this fish tank.

If you are looking for a quality aquarium but don’t want to overpay, we suggest taking a closer look at the Diversa Rectangle Aquarium. With this fish tank, you will be able to create a perfect environment for fish, underwater animals, and plants.

Since the set of this model includes only a fish tank, we consider it a better fit for those who already own all the necessary aquarium equipment. If not, note that you will have to purchase it separately.

The aquarium itself is a very solid choice since it is made of glass that is glued together with silicone. This lowers the risk of potential leaking and spoiling your floors or furniture, so you can safely put it pretty much anywhere in your house. The non-skid mat that comes included in the set offers great stability even on slippery surfaces and ensures that the corners of this glass aquarium won’t leave any scratches.

Moving on, you can purchase this fish tank in different capacity options, with the smallest one being 25 litres. There are 7 more size options up to 300 litres, so you can choose the one that fits your needs.

In a word, if you already own an aquarium and want to replace it with a better one or you are just going to get yourself some fishes, consider buying this model from Diversa.

Do you want to quickly and easily update your home or office interior? If so, we suggest getting an aquarium with some beautiful plants or exotic fishes. The URBNLIVING Aquarium Starter Kit includes everything you need for setting it up.

Firstly, you get a compact 18-litre fish tank with the dimensions of 42.5 x 21.5 x 31.5 centimetres. It can easily fit on a shelf or table. The walls of the aquarium are made of glass and it has a plastic framework that makes it look more stylish.

Secondly, the kit includes a basic filter pump which is a necessary thing for every aquarium. Thus, you don’t have to purchase it separately. The other good thing is that it works very quietly, so it won’t disturb you, your colleagues, or your housemates.

As for the rest of the set, it includes such decorative pieces as a fake plant, background poster, and half a kilo of bottom stones that allow you to decorate the aquarium the way you want. You also get a fish net that will help you to remove them from the water when its time to clean the aquarium.

All in all, this starter kit from URBNLIVING is an excellent choice for those who want to get a few fishes. Thanks to the rich set of accessories, creating a beautiful and cosy habitat for your new little friends will be a piece of cake.

If you are limited in space but desperately want to get fish or some underwater animal, there is a space-saving solution for you. The Fish R Fun Aquarium is a compact model that can still become a great home for a few fishes.

Starting off with the size, this fish tank has compact dimensions of 33 x 29 x 44 centimetres, so you can easily fit it on your working desk or even a coffee table. Yet, it still has enough space on the bottom to put some cute decorations there. The aquarium fits about 21 litres of water and has a filtration system for it already included in the set. You also get one free cartridge for it.

What is more, this aquarium comes with integrated lighting. The LEDs are securely hidden in a polycarbonate tube that protects them from water and humidity. Thus, there is a lower risk of shortcuts, which helps significantly prolong their service life.

And lastly, a few words about the design. This fish tank has a hexagonal shape with glass walls, a plastic bottom, and a big plastic hood. Both the top and the bottom parts come in black.

To wrap the whole thing up, we consider the Fish R Fun Aquarium a good compact option for all the fish owners who don’t have much space for wide aquariums. And the included accessories make setting up this fish habitat much easier.

The CROCI A2001988 Aquarium is a universal product that can serve both as a freshwater aquarium for fish and seaweed and as a terrarium for reptiles. It has a robust construction yet comes at an affordable price.

The manufacturer states that the capacity of this model is 25 litres, but you can actually pour only ~22 litres before it starts overflowing. The fish tank has a square shape, and the size of each side is 30 centimetres. Thus, it doesn’t require much space. Plus, you can put it on almost any surface thanks to the mat included in the set, which gives you more options for placing it.

Moving on to the materials, this open-top model has a simple glass construction with no plastic details. The material boasts great robustness thanks to its 5-millimetre thickness. Owing to that, it is not as fragile as some of its rivals.

As we mentioned before, this fish tank can accommodate different species of fish and other underwater inhabitants. The people at CROCi say that it is ideal for invertebrates, shrimps, crabs, and snails.
