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.
Schooling fish are particularly popular – fish that are only happy in a group of the same species, travelling around your tank in colourful packs.
As a general rule you should make sure to have at least six of these fish in your tank at any one time – and be aware that some species thrive when there’s a particular proportion of males to females (if there’s any doubt ask an expert at your local pet shop).
So, here are 10 of the best species of schooling fish for aquarists (people who maintain aquariums).
. Neon Tetra
The Neon Tetra is the UK's (and probably the world's) most popular tropical fish - and is the epitome of a schooling 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. You'll need a seperate tank if you want to breed then though. Photo: Canva/Getty Images
