Creating a fish pond is actually easy, as long as the first intention and purpose of what will be created, do not because of the desire for a moment seeing a nice fish pond belonging to a neighbor for example. Whether you want to make a fish pond for a beautiful home, or for self-reflection, or the need for the water element in the house, it may take a splash of water and feed the fish every day, it seems inappropriate to make a pond in the garden hoping to harvest a fish day "who knows".

depth and filter pool is also a major concern as a standard made pond, shallow is for small fish, medium or less than 60cm water depth is the standard pond, more than that is for big and expensive fish such as koi fish.
Well, so it's up to you choose which size, choose the size according to your will.
