A fish pond is a great feature to add to your garden and, once installed, you will be able to spend many pleasant hours watching the fish as they swim lazily around in the water.

As a result he no longer has to peer down into the water, but can enjoy his precious koi carp at eye level. Watch the video below and see if you think this is a good idea.
