It is estimated that around 10 per cent of British households own pet fish – making them the third most popular animal to welcome into our homes after cats and dogs.
From garden ponds filled with Koi Carp to the humble goldfish bowl – the UK is a nation of fish lovers.
And the Pet Food Manufacturers’ Association (PFMA) say there are an incredible five million indoor fish tanks in Britain.
There’s plenty of choice when it comes to adding fish to (well prepared and correctly set up) home aquariums, with pet shops offering a bewildering range of colourful and interesting finned friends.
But some fish top the charts when it comes to popularity amongst aquarists (the fancy name for people who maintain aquariums).
Here are the 13 species of fish that are most commonly found in living rooms around the country.

13. Rosy Barb
Found in the rivers of Afghanistan and Bangladesh, you ned to be a bit careful if you have Rosy Barbs in your aquarium. Firstly, they can be aggressive towards smaller fish. Secondly, they also are known for jumping out of the water - so make sure you have a well-fitted lid or you might end up finding them on the carpet. | Canva/Getty Images
