From garden ponds filled with Koi Carp to the humble goldfish bowl (although goldfish need far more space to live healthily and happily) – Britain has long been a nation of fish lovers.
There are an estimated five million indoor aquariums in the UK according to the Pet Food Manufacturers’ Association (PFMA) - that’s around 10 per cent of all housholds.
That makes fish of all sapes and sizes the third most popular pet in the land, after cats and dogs and cats.
It’s a great hobby, particularly for youngsters, and watching fish slowly swim around their home is wonderfully relaxing.
There’s plenty of choice for well prepared and correctly set up home aquariums, with pet shops offering a huge range of finned friends.
The first decision to make is whether you are going to pick a freshwater or saltwater tank - saltwater is a little more demanding - before choosing your fish breeds.
It’s important to ensure that you get the right fish for your particular aquarium or your pets will not be happy and healthy.
If space (and money) is no object then there are some incredible huge tropical fish you can opt to put in your enormous tank.
Here are 10 of the biggest - and most colourful - tropical fish for freshwater aquariums.
