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.
One thing to consider is that some fish tend to live considerably longer lives than others - the humble goldfish can live for over 30 years, while the aggressive Betta often won’t reach its third birthday.
Here’s how long 19 of the most popular freshwater tropical fish live for.

10. Suckermouth Catfish
Also known as the Common Pleco, the Suckermouth Catfish may not be the prettiest of faces but is useful to hoover up food that drops to the bottom of the tank. They are another species that can reach a grand old age - 10-15 years. | Canva/Getty Images

Another bottom feeding species that will keep your tank nice and clean, the Corydoras Catfish is native to South America and Central America. They live for 5-10 years. | Canva/Getty Images
