Koi are judged on five primary characteristics: Conformation, color, pattern, quality, and imposing appearance.
The annual two-day show is an opportunity to view spectacular show-quality koi on the City Hall lawn.
Vendors also had koi available for purchase as well as information on pond and filter design, and general equipment needed for the koi hobby.
The event included entertainment and an awards banquet.
