Setting up a tropical fish tank can be hard! Different fish will thrive in different conditions and, with such a diverse range of species, it's important to do a bit of research to ensure a healthy environment.
In this article, we'll discuss tank size, temperature and style, as well as heating, lighting and filtration systems. Along with a ranking of the 10 best tropical fish tanks in the UK on Amazon and Argos, you're sure to find one that suits your needs.

The most important feature of a tropical fish tank is the heater. Tropical species need a water temperature of around 25 - 27°C in order to stay happy and healthy, so without a heater, your tank won't be a tropical tank at all.
You could always shop for a heater separately to convert a freshwater tank into a tropical one, but a tank with a heater included will be more convenient and cost-effective. Other useful accessories to look for are filters, lighting and thermometers. These are must-haves if you want to create the best environment for your fish. Plus, they'll make monitoring and cleaning the tank much easier!
Keep them satisfied with the Best Fish Food!
As well as maintaining an adequate temperature, choosing a tank with plenty of space is also incredibly important. Depending on the size of the species, the required space will vary, so it's always important to research your desired species first.
As a general rule, you should aim for a minimum of 2 litres of water per fish so that they have plenty of space to move and grow. As well as giving your fish more space, larger tanks are usually easier to clean.
It's a common misconception that smaller tanks are easier to maintain, but if a tank is too small, the filtration system will cycle the water much faster than it would in a larger aquarium. A higher volume of water means less frequent cleaning, so keep that in mind if you only have a few hours a week to devote to maintenance.
We've ranked the Best Fish Tank Filters to help keep the water clean and clear.
Rectangular tanks are the most common, with plenty of floorspace for ornaments and plants. The greater length means that tanks are also great for your fish, as they provide more space for them to swim horizontally. Since most fish swim back and forth rather than up and down, this shape allows them to make the most of the tank's volume.
If you're not planning on keeping too many fish or are hoping to house a single species, a tall tank may catch your eye. Tall tanks provide a unique look, but the horizontal swimming length will be significantly shorter. Even so, a few small fish could live happily in a tall tank. Plus, they're ideal for aquascaping as it allows tall plants more space to grow.
Square tanks are typically the smallest on the market, making them the best option if you have restricted space. Bear in mind that if you choose a square tank, the fish will have limited room for movement. So it's important to remember the 2 litres per fish rule to ensure you don't overpopulate the tank with obtrusive plants or decorations.

Using the lighting and filtration system, you'll be able to monitor and maintain your tank's water quality with ease. The heater ensures a suitable temperature, while the plants, ornaments and gravel will add the final touches to your setup.
If you'd prefer a mid-sized option, this tank from Tetra has been described as the perfect starter kit. With a 105-litre capacity, it will be able to house a significant number of fish and plants.
Each tank includes lighting, heating and filtration, offering an all-in-one purchase to help maintain the ideal living conditions for your new pets. Plus, it comes with a 2-year manufacturer's guarantee from a petcare brand you can trust!
The package also includes a thermometer to help monitor the water temperature. It even comes with water conditioner to treat the tank, maintaining an excellent environment for your fish to thrive.
What's more, the Ciano filter included in this package ensures optimum water renewal for less frequent cleaning. Paired with the heater and LED lighting, this kit makes for an excellent tropical setup.
The quiet Ocellaris canister filter is powerful enough to cycle the 145 litre volume efficiently. It's energy-efficient too, so you won't have to worry about your aquarium raising the monthly bills.
Of course, the black cabinet may not fit into everyone's home decor and, unfortunately, the brand doesn't offer any other colours or designs. That said, if you're after an all-in-one tropical tank with additional storage, this may be the one for you.
This square tank features a digital thermometer with readings displayed on the inbuilt LCD screen. This makes tracking water conditions easy, and means you won't have to ruin the look of your aquarium with peripheral accessories.
The 12 litre capacity is the smallest on our list, so it will only house up to 6 fish. If you need something for a particularly small space, though, it could be just what you're looking for.
Although the tall design is ideal for creating a modern and unique look, it does limit horizontal swimming space for your fish. We would recommend researching different species to ensure your chosen fish will be comfortable in this tank.
That's because this tank doesn't include a heater or filter, so you'll need to purchase those separately to turn this into a tropical aquarium. However, even with this additional cost, it could work out much cheaper than a complete kit of a similar size.
Just be aware that the square shape won't fit traditional fish tank stands, and doesn't come with its own stand either. If you already have space on a sturdy table or cabinet, however, it could be a great addition to your home.
