When you are looking to have a natural-looking pond, it is very important to remember that it takes time for the “naturalness” to develop.
If you want to have a koi pond in your garden (or workplace) then it really is advisable to have an expert do it for you.
Koi can be extremely expensive and are relatively fragile…if you get things wrong. When you get things right, they are hardy and beautiful fish.
Did you know some koi carp can be worth up to £50,000 each?
