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.
1. Neon Tetra
It'll come as no surpise to anybody who has ever owned an aquarium that the Neon Tetra is the UK's (and probably the world's) most popular tropical fish. The tiny fish's bright red and blue colouring and ease of care are a winning combination for beginners. They originally come from backwater streams in the Amazon basin in South America.

2. Guppy
Second place goes to the Guppy - also known as the Millionfish or Rainbow fish - which have large multi-coloured tails and originally come from northeast South America. In common with some other common aquarium fish, they live-birth their young, rather than laying eggs. Many fish owners have been delighted to wake up one morning to find tiny Guppy babies have arrived overnight. Photo: Canva/Getty Images
3. Platy
Another live-birther, the bright orange Platy takes the last podium place. Native to the east coast of Central America and southern Mexico, Guppies bought in UK pet shows are likely to be the reult of the interbreeding of two distinct species - the Southern Platyfish and the Variatus Platy.

4. Angelfish
There are a three different species of Angelfish, all of which originate from the Amazon and Orinoco Basins of South America. Popular due to their instantly-recognisable shape and elegant markings, they shouldn't be kept with smaller fish like Tetras and Guppies as they can be very aggressive towards other species.
