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

1. 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!

Keep them satisfied with the Best Fish Food!

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

2. 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.

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

3. 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. 

Decorate to perfection with our Best Fish Tank Ornaments!
