23" round substrate, 1" thick, ready to hang. All of the substrates for this series have been custom made from MDF that is 1" thick.
I started this series after hearing a legend about koi fish swimming upstream in Yellow river in China. I really enjoy going to places that have koi ponds. One of my favourite places in Albuquerque was Japanese garden with a huge pond in the botanical garden. I used to spend hours there, studying, contemplating, even writing my dissertation. Watching the fish has a relaxing effect on me.
