You can't say enough good things about Kevin and Genki Koi. Some of the reviews of people complaining about the price is mind blowing. These are hand selected fish from THE best breeders in the world. I got two Isa Showa with certificates from Isa. There are very few breeders in the world eligible to sell these. Then to top off an amazing selection the service is amazing. Kevin held fish for me while I waited for a water correction. Called before shipping, day of shipping then followed up when they arrived. 5 star all the way through. Customer for life!! read more

Super passionate and knowledgable team. Really helped educate me on the hobby and break down basic principles.

If you are looking for koi or goldfish, this store is the one to go in the bay area. I've been to almost every fish stores in bay and I recommend to go to this place. However they are pretty pricey compared to other online fish shops. read more

6/18/20 Re: COVID: Open during Yelp posted business hours, barely any customers (saw one other customer when we were there),spacious inside with plenty of ventilation and staff is masked up. Wow! Heaven for Koi and fancy goldfish lovers. I had no idea there was a place like this right here in San Jose. Tucked away in a warehouse on 10th St near SJ Giants stadium/Senter Costco, this location offers full grown competition grade koi and fancy goldfish. Many of the mature Koi are hand selected during an annual trip by the owner Kevin in Japan. Others are shipped from Japan and Thailand. There was a large batch of fancy goldfish just shipped upon our arrival and currently in quarantine...something something ironic. Anyhow, the prices appear reasonable for the size and quality of fish they offer. About $75 for smaller fancy goldfish like Ranchu and Oranda up to $150 or so for larger. Koi range widely based on markings, coloring and lineage...and probably other factors a noob like me in unaware of, but that the folks at Genki would happily explain. Every fish we saw looked to be in peak condition. Bill, who turned out to be the owner, Kevin's Brother-in-Law patiently helped us through all our questions and gave us plenty of space to browse the fish. It was nice to know this rather impressive endeavor was still handled by folks who really care about the hobby, family even. He also provided guidance on maintaining color and health of the fish. Another gentleman, Dai also helped us with all of goldfish-specific questions since Bill specializes specifically in Koi. During non-covid times this organization also hosts auctions and events for Koi enthusiasts. Hopefully we will be able to join in the future. We'll be back soon to check out the fish once we are ALL out of quarantine. If you are looking for your next Koi or considering upgrading your freshwater tank with some incredible goldfish specimens...or even just in the neighborhood Genki Koi is definitely worth a visit. read more

Premium prices for average-fare. I really wanted to patronize this aquatic establishment but the pricing on their fish is STEEP and quite the hard pill to swallow for their average to good offerings of koi and fancy goldfish. If you're looking for value, this is the wrong place to go! I am an avid keeper of fancy goldfish for over a decade now and the point of my visit was for fancy goldfish; one of Genki's specialties. For their normal-fare of average-sized to large koi and fancy goldfish, the prices here are an outright cash grab or highway robbery. ***They sell fish for $100-$400 that would cost $35-$150 tops at their competitors.*** Their selection and quality just does not justify their exorbitant pricing. I was unable to find any show-quality fish which you would expect at the price point they command. Putting value in prospective, compared to coast gem that also specializes in handpicked first-choice fancy goldfish and mailing them to you from san diego, there's much better fish there for cheaper. Even after UPS takes their next-day-air shipping share! The savings over this place would be enough to eat-out for my family for dinner at a sit-down establishment. Not to mention, you're able to save a trip here. Pricing of their supplies on hand is fair and palatable but that's pretty much where all the good ends at. If you're looking for XXL-XXXL koi to stock your massive pond with, where a yard stick is more appropriate for scale and a bathroom scale for determining weight, look no further. This is the only place that sells such impressively sized koi in the bay area. If you're on the market and have the facilities to successfully keep such fish, you already know the 4 digit denomination for prices. Word of the wise, if you're tone-deaf on value and still plan on acquiring fish from here, please take the time to observe prospective selections for a couple minutes before committing. Especially for their fancy goldfish. I noticed quite a few sickly fish on my visit, in all places including their display tank near the counter where they keep their top-shelf "best" fish. Swim bladder is especially problematic with their stock. On my particular visit I had my eyes on an red/ black "apache" oranda that the employee would shy away from answering my questions about its health after I noticed it tended to loiter at the top of the surface of the water and unable to swim down. read more

This place have big koi fish and they are nice and expensive. We were looking for a new place for koi fish food since the one we normally patron is closed. Was very impressed with the layout and the size of the fish. Will need to pick up a couple of extra shifts to afford them. Will keep them in my Rolodex for future reference. read more

My husband and I stopped by on Father's Day to buy his grandfather a gift. They have such a large selection of koi ranging from $100 to a couple thousands. We chose this beauty to add to his collection of koi. The price tag was hefty, but it was imported from Japan, came with a breeder certification, and we wanted quality over quantity. The quality of this fish is superb, and it was big for a one year old. I'm excited to see how big it'll become in the next year. Thank you, Genki! read more

There are some nice fish, but Champion Nishikigoi has a MUCH bigger selection with higher quality fish.

I've traveled up and down the Peninsula and Genki Koi is THE SPOT for quality Fancy Goldfish and Koi in the Bay Area. Lookout for the sandwich board sign as it is quite hidden and tucked behind a large building. They have recently started offering many beautiful and rare Thai imported Ranchu, Oranda, Demekin, and more. I am always pleased with the quality and health of their fish and will definitely be back again. read more

Best place to get a premium selection of goldfish (they had a large selection of Ranchu, Oranda, Tamasaba, Demekin, and Buffalo ranchu). Of course they have a beautiful selection of Koi as well, but I primarily was searching for goldfish. Prices were slightly higher than a typical fish store or chain pet store, (Genki: $75+ for Ranchu and $35-75 for Tamasaba). However the quality and coloration of these fish are far above anything that I have seen available in the Bay Area, well worth the price if you love goldfish! I purchased a Tamasaba goldfish ($50 for a medium sized fish 2-3 inches) and 2 weeks later I am very happy with the purchase. This is the first location in the Bay Area that I could purchase this fish outside of imports or online shipment. I will absolutely be back for more Tamasaba and perhaps other goldfish types from Genki Koi! read more

I am a fancy goldfish lover! I found Genki Koi by chance, and I'm thrilled I did! They have an Amazing Selection of extremely healthy Fancy Goldfish. I will always reward myself with one of their gorgeous varieties! Even if your just beginning your journey with quality fish Genki Koi is not just for Koi fish lovers anymore, and so worth taking a look! And while you're there you have to look at their beautiful Koi Fish! Thrilling! They can even ship fish! Now I have a very cool option for my fellow FGF lovers birthday, or Christmas gifts! Thanks Genki for bringing me a bit of Joy during this Quarantine! read more

I absolutely would recommend Genki Koi to anyone looking for high quality goldfish or Koi. I have been searching for Tamasaba for a long time and when I contacted Kevin of a genki Koi, he was able to get me three of them. I was able to ask for videos of the potential fish I wanted and they were able to get me the perfect Tamasaba. Being based out if state and shopping online can be challenging, but Genki Koi made it easy to shop with confidence. I was shipped three healthy Tamasaba and I got a high quality Ranchu. The whole process of getting fish sent from out of state was easy. Definitely one of the best places to get goldfish and Koi. Thank you Genki Koi for getting me the Goldfish I've always wanted- Tamasaba read more

I recently bought a couple Thai calico oranda from this store, they are absolutely amazing! Probably the best quality u can get in the area. The calico oranda I bought have super spread out tails, very nice body shape and attractive colors, which make they stand out among the regular oranda. They are for sure a bit pricey, their goldfish price range from $50-$500. read more

I tried to order pond supplies from this vendor online. I live in Northern California and my pond sterilizer broke on a hot holiday weekend. Knowing that time was of the essence, I looked for an online vendor as close to my home as possible. I found GenkiKoi online (less than 100 miles away) and made my emergency purchases complete with notes about the urgency. After 6 days without my product, I contacted Genkikoi and requested an update about my order. They responded quickly that they had been out of town in Southern California and that they did not have the items in stock. Since returning, they had not noticed my orders. They were very quick in making my refund, but the time lost was essential and my pets are still in peril. My recommendation to Genkikoi is that they spend time on updating their website or have someone monitor their website when they are away. This is just a best business practice. At this time, I can't recommend this online store. read more

This place has a ton of nice goldfish, including the more rare breeds like jikins. The koi in the largest pond there are absolute titans, this would be the first time that I've ever seen 3ft+ koi. Prices are kinda steep, but the quality is definitely there. read more

Bill was awesome. Super knowledgeable and beyond helpful. Genki Koi has earned a customer for life. Genki Koi's selection is impeccable. My daughter and I walked out with 7 Koi pics below. read more

WOW!! Genki has exceptional fancy goldfish and outstanding customer service! I'm a bit of a goldfish geek and recently rebooted my 180 gallon aquarium. Bill, Kevin and Dai have gone above and beyond to answer my questions, update my knowledge and help me get the most out of my system. I have purchased 3 beautiful fish from Genki so far and can't wait to come back for more show quality fish. I have kept fancy goldfish off and on for 25 years and had recently gotten very discouraged about the whole hobby and was considering selling my tank because I had had so many bad experiences with poor quality fish from other places. I was referred to Genki and it has completely reinvigorated my enthusiasm for the hobby! These are the most healthy, high quality fish I have ever had the pleasure to keep. Every time I have come here (4 times in the last month lol) the fish all look healthy and well cared for. They have such a variety of Thai and hybrid Ranchu, Orandas, Demekins, Ryukins, Jikins...I take twice as long to decide because of so many lovely specimens to choose from. Their quarantine procedure gives me peace of mind that the fish have been screened and that they care about their customers' tanks. I also love that they're invested in the local community and growing the hobby with their Goldfish Palooza events. We are so incredibly fortunate to have a place like Genki. read more

Great place for koi fish and fancy goldfish! I've visited a good number of pet/fish stores, but none of them compared to the unique and beautiful species that Genki Nishikigoi has!

Wow. I wish that when I started getting into goldfish, I would've just gone straight to Genki! They have very nice and rare breeds of goldfish, quality that you can't find elsewhere. I didn't see a single sick fish on display. You can tell they really love what they do. After purchasing a black ranchu, Kevin approached me with advice and tips for black ranchu which I learned through him are more susceptible to health issues. I've never seen a fish store care about their fish this much! Glad to have finally visited Genki Koi and look forward to the West Coast Goldfish Palooza when it becomes safe again! read more

Clean, abundant large koi, knowledgeable, friendly, and seem to really care about Koi and your pond. I took off .5 star because the older gentleman with weak English that works there could have been a little bit more patient while I was trying to select my koi. He would ask, "so which one do you want" a few times when contemplating the last koi. I know it took a little long but please don't rush your clients when trying to choose their pet, even if they're fish! I took another .5 star because the location was hard to find. You have to drive into a business parking lot to find the location, as the store front is not facing the street as you're driving looking for it. They did however have a small sign in the entrance of entering the lot so that helped. Overall, I ended up leaving with 5 (25$ EA. Buy 4 get 1 free). The younger gentleman there asked me questions about my pond and suggested an air pump for my pond when the weather gets hot (90s) to provide the koi more oxygen and I left learning a few new things about different species of koi. They seem to be passionate about Koi and I would probably bring my dad here for fun. I highly recommend if you are a hobbiest or looking for a champion koi! read more

Came to get a new goldfish and was so impressed by the unbelievable selection. The koi are just amazing to see. A hidden gem. A must see. This is the best place to buy koi or goldfish in the area. Thank you Genki Koi. read more

Talk about WOW!!! My first impressions of this place and reading about this place from Yelp, is really true! Nestled in the back of the San Jose warehouses, is this really cool shop. I have been to stores that sell goldfish and stores that sell fish in general, and I can guarantee, this place is solely dedicated to fancy goldfish and koi. While this location was a tad difficult to find (would recommend a bigger sign), entering this store was super cool! The staff were super friendly and knowledgeable. I had the chance to talk with the owner and he mentioned that fish are all hand selected by him and shipped to the store. So no funky fish like Petsmart here! Prices, yea, are a little expensive, but you get what you pay for, and its mainly due to shipping overseas, so I will not gripe about that. The goldfish I got are amazingly beautiful and were advertised as "show fish". I definitely feel I got that when comparing them to my other goldfish in the tank. The owner takes the time to show you his inventory, show you his amazing koi palace, which I kid you not is freaking amazing! I could sit there all day and just watch them swim!! But the owner also shows you what kind of foods they eat, care they will need, and has always been on standby to answer my questions if I ever got stuck on anything. Thank you for helping me get the fish of my dreams, and completing my amazing 93G goldfish tank! read more

Large selection from on-sale goldfish to extra large koi. The folks there are always super nice and helpful. By how excited they are you can easily tell how they've turned a hobby they loved into something they could spend their days doing as a business. since starting a backyard pond I've been here many times and they've helped me figure out what kind of fish to keep, how to keep the pond healthy with the right (and cheapest) equipment, what food and how to feed, which plants to grow, how to avoid disease in the pond, and even helped me stop worrying about new behaviors I saw in the fish. Zero sale pressure too. Have brought the kids just to see the large koi. They even explained to me how a much particular (and cheaper) goldfish they had was more valuable than an expensive breed next to it. read more

We're so happy to discover this shop! Magnificent koi fishes. We got some ranchu and oranda & I can tell they are really good quality and healthy. I would say the best in the bay area so far. We're actually getting an even bigger tank than originally planned this week. Also appreciate the new info/ tips and kind customer relations! read more

I have known the owner of this great store for 5 years. Whenever I need advice about anything related to koi, Kevin (owner) takes time to explain it to me. He has a a wide array of knowledge and he is definitely the go-to-person if you need help with anything or if you want to purchase fish or supplies for your pond. He is super flexible and easy-going. Unlike many stores, the shop owner and employees aren't pushy and don't force you into buying anything. They' really want to help you and they'll bring out the best of their abilities to give you all the advice you need. I highly recommend this shop to all koi-fish owners and and to people who are interested in being one. -T.N. read more

Kevin and his associates were extremely helpful during my first visit to their shop. They diligently explained how my pond system worked and helped me figure out what was wrong causing my pond to be filled with algae. From complete knowledge of koi, koi pond systems and excellent customer service, if you ever need advice or koi products/ fish this is the place to go. They have an amazing variety that you will not be able to find at any other pet store in the entire Bay Area! They are diligent and passionate about their work and are always thinking about what is best for their customers not just trying to make money for themselves. read more
