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 (people who maintain aquariums).
Here are the 11 species of fish that are most commonly found in living rooms around the country.
9. Siamese Fighting Fish
Siamese Fighting Fish have been highly-prized creatres for well over a century due to their colourful and ornate flowing fins. As their name makes clear though, they can be aggressive and shouldn't be placed in a tank with other large-finned fish, while two males in close confines may well fight to the death. They tend to do best in tanks with smaller fish that gather in shoals - such as Tetras. Photo: Canva/Getty Images
10. Red-tailed Black Shark
Despite its name, the Red-tailed Black Shark is more closely related to the humble Carp than the Great White. Critically endangered in its native Thailand, this fish is common in aquariums, where they are all captively bred. Photo: Canva/Getty Images
11. Swordtail
No prizes for guessing how the Swordtail got its name - with its distinctive tail differentiating it from its close cousin the Platy. Selective breeding means they are available in a wide variety of colours including black, silver, orange, red, and mixed patterns. Photo: Canva/Getty Images
