From garden ponds filled with Koi Carp to the humble goldfish bowl (although, goldfish really need far more space to thrive) – the UK is a nation of fish lovers.
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.
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 interesting finned friends.
One think you should be aware of is that while many of the most popular fish, such as the Neon Tetra, need a heated tank, others are more than happy to chill in a cold water aquarium (although you’ll still need a filtration system to keep them in tiptop fishy-shape).
Here are 10 species of fish perfect to populate an unheated aquarium.
5. Weather Loach
Also known at the Dojo Loach, the Weather Loach is so named for its ability to sense barometric pressure changes - frantically swimming or standing on end when a storm is approaching. Native to East Asia, they are playful and quirky bottom-dwellers that enjoy cooler water with plenty of hidey-holes. | Canva/Getty Images

7. Paradise Fish

8. Ricefish
Also known as the Glassfish, the Ricefish gets its name from the fact that it can be found swimming around Asian rice paddy fields. Tougher than they look, they don't mind cool water and are the perfect fish for those who only have room for a small aquarium. | Canva/Getty Images
