This is the pond that started out as a water garden, then I added feeder goldfish. One of the white goldfish looks like a Tancho Kohaku, It's a goldfish not a Koi, I just put in my 2 Shubis from the other pond. This is the place where I will build a larger pond. It will either be a preformed 255 gallon pond or I will break concrete and dig into the current patio to double that. The above ground is cheaper and easier. I will decide later.
