About Zwally Koi
Zwally Koi is based in Ashton, Maryland, where koi, ponds and a garden setting come together at our facility.
Our collection includes Japanese koi sourced directly from breeders and through Kodama Koi Farm.
We study the color, pattern, body shape and movement of individual fish, and share the origin details we can document.
Keeping koi is an ongoing practice of observation and care. The setting lets visitors see each fish in motion and ask questions about its long-term home.
Arrange an appointment to view current koi and tell us what you are looking for in your pond.
Our Purpose
We believe koi bring movement, beauty and a reason to pause beside the water. A well-kept pond and a thoughtful garden invite people to notice how the scene changes with the seasons.
Choosing a koi should be as considered as caring for one. We share what we know about each fish and help buyers think about the pond that will become its long-term home.
How we choose our koi
We source Japanese koi from breeders, both directly and through Kodama Koi Farm. We look at color, pattern, body shape and movement as we choose and care for fish. Where a listing identifies a breeder, it reflects the information available for that individual koi; a mixed shipment may have more than one possible breeder.
