Frequently asked questions

Create a free account, open an active auction and place your bid. Your bid must be at least the amount shown for the auction at that moment.

Before your bid is definitively placed, you will see the amount once more. Your bid is only registered when you choose Place binding bid.

A bid that has been placed is binding and cannot simply be withdrawn.

Yes. When automatic bidding is available for an auction, you can set a maximum amount.

The system then bids automatically on your behalf in the required bid increments, up to the maximum amount you have set.

While the auction is running, you can raise or lower your maximum bid or stop automatic bidding. Your maximum bid can never be set lower than the highest bid already placed on your behalf.

Bids that have already been placed remain valid and binding.

Have two bidders set the same maximum amount? Then the maximum bid that was registered first takes precedence. If you change your maximum, the time of that change counts as the time of registration.

For some auctions, the closing time is extended automatically when a new bid is placed shortly before the end.

The auction page shows whether this extension applies and by how many minutes the auction is extended.

If another bid is placed during the extension, the closing time can be extended again. This gives every bidder the chance to respond to a late bid.

You win when you hold the highest valid bid at the moment the auction definitively closes and any reserve price has been met.

You will then be notified and the koi you won will appear in your account.

Some auctions may have a minimum selling price. We call this the reserve price.

If the reserve price has not been met when the auction closes, no purchase agreement is concluded.

When a reserve price applies, this is shown with the auction.

After winning an auction, you will receive the payment details by email and in your account.

Payments are processed securely through Mollie. The payment methods available to you are shown at checkout.

The full purchase price and any transport costs must be paid within 7 days of the auction definitively closing.

Yes. You can collect your koi free of charge by appointment at Koi & Vijverbouw in Wintelre.

We carefully pack the koi in water and oxygen and prepare it for the journey.

Transport is currently possible to:

• the Netherlands
• Germany
• Austria
• Luxembourg
• Slovakia
• the Czech Republic
• Poland

Transport costs depend on factors such as the destination, weight, volume and the carrier's current surcharges. You will see the transport costs before you complete your payment.

Transport takes place outside our winter break and as long as conditions allow the koi to be transported responsibly.

You can find more information on Shipping and payment.

Outside our winter break, we generally ship koi once a week, on Thursday.

Within the Netherlands, a shipment is usually delivered the next working day, on Friday. For international destinations, the transit time may be longer and depends on factors such as the country and postcode.

During the winter period, we observe a temporary shipping stop. During this period we do not transport koi, because low temperatures and changing weather conditions can make transport less responsible.

The current winter break period is clearly stated on Koi Auction Europe. As soon as conditions allow and the winter break has ended, we resume weekly transport.

Outside the winter break, too, we may postpone a transport if, in our judgement, the temperature, weather or other conditions are not suitable for responsible transport. In that case, we will contact you to arrange a new transport date.

For transport, the koi is carefully packed in water and oxygen and prepared for the journey.

Transport takes place without active temperature control. That is why we assess in advance whether the temperature, weather and other conditions are suitable for transporting the koi responsibly.

After import, every koi stays in our own quarantine at Koi & Vijverbouw for at least 4 weeks.

During this period, we carefully monitor the health and behaviour of our koi and test for KHV and CEV. If there is any doubt about a koi's health, it is not offered at auction.

With a living animal, a health check or test is always a snapshot in time and can never fully rule out every future health risk.

Although every koi stays in our own quarantine for at least 4 weeks before it is offered, we recommend that you first quarantine a new koi yourself after receiving it, before adding it to an existing koi collection.

We particularly recommend this if you already have a valuable or vulnerable koi collection. Your own quarantine period gives you the opportunity to observe the new koi separately and reduces the risk of any health problems affecting other fish.

For every koi, we state the available information about the breeder and origin.

If a breeder's certificate is available for a koi, this is stated with the auction and the certificate is, of course, supplied with the koi.

Not every koi comes with a certificate as standard.

On the auction page you will find photos, videos and the available information about the koi.

Would you like additional information before bidding, or do you have a specific question about a koi? Feel free to get in touch with us.

If you would like to view a koi at our premises in Wintelre, please contact us in advance so we can confirm what is possible.

A bid that has been placed and an auction that has been won are binding. However, if you buy as a consumer through our online platform, you have the statutory right of withdrawal that applies to distance contracts after receipt.

Because a koi is a living animal, special considerations apply to returning it and to the return transport, including health, welfare and any reduction in value.

You can find all the information about this on our Returns and withdrawal page.

Yes. At Koi & Vijverbouw, we test your pond water free of charge.

Bring a small bottle of pond water to our location in Wintelre. We can then check the water values and, where needed, advise you before you add a new koi to your pond.

Do you notice anything about the health or condition of your koi? Please contact us as soon as possible.

If possible, send clear photos or videos and include relevant information about, for example, acclimatisation, housing, water temperature and water values.

With health problems, acting quickly can be important and every hour can make a difference.

Feel free to get in touch with us. We are happy to help with questions about a koi, an auction, payment, collection, transport or using the platform.
