There's nothing more relaxing than watching pet fish swim around in their tanks. If you're introducing a new fish into your family or just looking to branch out into looking after an aquarium, the first thing you'll want to invest in is a decent fish tank.

It's hard to know where to begin. As well as plants, live rocks and food, you'll want to think about water pumps, filtration systems or even water heaters to go alongside your tanks. Look no further though, because we've been on the hunt for the best fish tanks on the market.

From tropical aquariums to fish tanks for kids, we've rounded up our favourite bestsellers, so you can choose the best aquarium easily.

What fish tank should I get?

First things first, you'll want to think about which fish tank will be right for you - there's a range of tanks out there.

You'll want to think about the size of your tank first. How many fish do you plan to buy and how much space can you afford? If you're new to being a fish parent, you may want to start small. Most fish owners should go by the rules that one inch of fish should have two gallons of water (and fish tanks can go up to sizes of 65 gallons!).

Next, consider saltwater or freshwater tanks. This will all depend on what fish you want to buy for your home. Freshwater tanks are arguably less maintenance, but saltwater aquariums usually allow more colourful and vibrant fish.

Make sure to remember you'll need to acclimatise your fish in your tank too, so you may want to invest in a smaller, temporary aquarium for them to adjust in.

Every fish is different so make sure that you know what you're investing in. Think about how much space they require, what food they need, the ph tolerance of the water and what plants and environments they thrive in.

What do I need for an aquarium?

Aquariums usually need a variety of other accessories to make it a comfortable living space for your fish.

Firstly, fish food is extremely important for your fish to survive. Make sure you get the correct option because some fish have specific requirements. Never overfeed your fish as this is easily done and can be fatal.

Inside the tank, you'll want to think about water conditioners, fish filters, heaters (especially for tropical fish), window cleaners and air pumps.

On the other hand, you'll also want to consider accessories around the tank which your fish can enjoy. Substrate and live rocks for, gravel and sand for the floor, lighting, plants and stones can all be added in your own way.
