From garden ponds filled with Koi Carp to the humble goldfish bowl (although goldfish are far happier living in a larger tank) – the UK is a nation of fish lovers.
The Pet Food Manufacturers’ Association (PFMA) say there are an incredible five million indoor fish tanks in Britain.
That meams that roughly 10 per cent of British households own at least one fish – making them the third most popular pet after dogs and cats.
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 that will happily live in the corner of your living room.
If you’re setting up an aquarium for the first time it’s worth noting that, when it comes to price, some rare fish can cost tens of thousands of pounds and will be out of reach of all but the wealthiest aquariasts (the posh name for people who maintain aquariums).
Luckily for most of us though, some of the most popular - and most beautiful - fish cost very little.
Here are 10 of the most inexpensive.
