Best koi fish seller I’ve been to. I’ve bought koi fish from here for the last 6 years, and I was always impressed by the customer service, quality and beauty of fish. I have bought about 15 koi fish here, ranging from $3000 - $600. All beautiful “keepers”. The premises are clean and professionally run, the place is huge and the choice is vast. Just recently, I discovered that this place is fantastic, in a different way: I moved to San Francisco and the professional who built our new pond, recommended a seller in Oakland (a shorter drive, in other words; and it was supposed to be top notch). I was so disappointed (little choice, the prices were very high) when I got there that I turned on my heels and drove all the way down to San Jose. We got 4 gorgeous, healthy, lovely koi fish to a very appropriate price. The staff is always super friendly and in a good mood, which is always lovely to witness. Makes the buying experience even better. The fish are handled carefully and gently. And I am always in awe when I look at the biggest koi fish they have - majestic, curious, smart creatures! To sum it up: I will never go to any other koi fish seller. This is, hands down, the best in the entire broader area!

My beautiful Showa arrived first thing in the morning. In great health. Communication and service was excellent, just like my new buddy. He will have a brief stay in the quarantine tank before joining his buddies, but he is not alone. Put one little Chagoi in with him. Thank you very much. Looking forward to my next purchase with you. 😀

Best Japanese koi available in California in my experience. Pricing is very appropriate for some VERY good koi. I've bought koi from Paul, Tom and Champion for many years now. Never disappointed.

Ordered some live koi to be shipped to East Coast from 3 different companies. Champion NIshikigoi were definitely the best! The fish were actually larger than advertised. They were better quality and color than expected and were eating almost immediately. Very happy with quality of Koi and service. Would highly recommend.

They have such beautiful fish that I can't afford! But the staff has always offered kind help and advice for purchasing less expensive fish for my own pond. And it may not be as cheap as ordering food online, but I know that the food is fresh and I can get recommendations based on the season, weather, etc. They also have the chemicals and accessories for the pond - everything you need really and knowledgeable people to help you choose.
