Not only do I enjoy pursuing beautiful native trout, but I also have a fascination with koi. I have a small backyard koi pond with five fish in it. I also keep a 300 gallon quarantine tank running in my basement, which now houses one fish for the winter. While the picture isn't great (no polarized filter), these are my two most valuable koi, in regard to price. The top one is an Omosako showa, while the bottom is a Koda sanke. This is another hobby of mine that can become an overwhelming obsession (and a real financial drain if one isn't careful).
