From garden ponds filled with Koi Carp to the humble goldfish bowl – 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.
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 some fish favour the bottom of the tank, while others are happier nearer the surface - combine the two and you’ll have a well-balanced aquarium.
Here are 10 of the best and brightest top-dwellers.

5. Guppy
One of the world's most popular - and colourful - fropical fish, the Guppies are lively, brightly colored fish that may visit other parts of their aquarium home, but are happiest near the top of the water.
