How to Choose a Tropical Fish Tank in the UK

Key Points to Consider
  1. Ensure Your Setup Includes a Heater to Keep a Tropical Temperature of 25 - 27°C
  2. Choose a Tank Volume With a Minimum of 2 Litres of Water per Fish
  3. Consider the Shape to Provide the Best Environment for Your Fish

Use Heaters to Maintain a Temperature Between 25 - 27°C and Look for Additional Accessories Like Filters, Lighting and Thermometers

Use Heaters to Maintain a Temperature Between 25 - 27°C and Look for Additional Accessories Like Filters, Lighting and Thermometers

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!

Consider Your Chosen Species’ Space Requirements and Always Opt for a Tank With a Minimum of 2 Litres of Water per Fish

Consider Your Chosen Species’ Space Requirements and Always Opt for a Tank With a Minimum of 2 Litres of Water per Fish

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.

Consider the Shape: Rectangular Tanks Provide the Best Environment for Fish, Square and Tall Tanks Are Suitable for Certain Species and Aquascaping

Consider the Shape: Rectangular Tanks Provide the Best Environment for Fish, Square and Tall Tanks Are Suitable for Certain Species and Aquascaping

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.

The discreet pump inside this 58 litre tank will ensure you're not overwhelmed by aquarium noise. This will be especially useful if you plan to set up your tank in a bedroom or a quiet area of the house. The quiet filters are also going to be less stressful for your fish.

A Sleek, All-Black Cabinet to Tie In With Modern Home Decor

This rectangular tank boasts a 130 litre capacity stored on top of a sleek all-black cabinet. Better yet, the included lighting, filter and heater will make setting up a tropical aquarium easy. 

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.

Keep an Eye on Water Temperature With the Inbuilt LCD Thermometer Screen

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.

Unique Rectangular Tank With Hidden Filtration System

The hidden filtration system within this tall rectangular tank will make your aquarium look even better under the canopy lighting. The rounded corners also mean you'll get a perfect view from any angle

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.

A Large Capacity Tank for a Bargain Price

Considering the 240 litre capacity, this tank is extremely well priced when compared to those of a similar size. With a stand and lighting included, you'll have almost everything you need to display your fish with pride. 

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.

Minimalist Design With Discreet Lighting and Filtration

For a modern design that catches the eye, this 30 litre square tank could be ideal. The canopy lighting and hidden filtration system ensure a minimalist look, with discreetly concealed cables. 

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.
