Can the Yoshikigoi I purchase overwinter with you?

At suitable receiving water temperatures (above 15 degrees Celsius), the Yoshikigoi purchased be usually be shipped within 14 working days  An exception to this rule is when the temperature of the water in the buyers pond is below 15 degrees Celsius.

Below 15 degrees Celsius receiving water temperature, all Yoshikigoi purchased by the buyer may remain at Yoshikigoi Farm without cost until the temperature of the receiving water at the consumer is a minumum of 15 degrees Celsius.

If the water temperature at the customer is already above 15 degrees Celsius, the Yoshikigoi can stay at the Yoshikigoi farm for a maximum of 2 weeks, however, this is only by mutual agreement and after written confirmation by Yoshikigoi to the customer.

If the purchased Yoshikigoi must remain on the farm for more than 2 weeks from the date of purchase, we will charge an amount of €7.00 per week for each purchased Yoshikigoi, unless otherwise agreed in writing by both parties.

The cost of €7.00 per week per Yoshikigoi is to cover the maintenance cost of each Yoshikigoi purchased.

If something goes wrong with your Koi during this period, such as colour loss, infections, or other health problems, they will be replaced by a similar koi or a full refund given.

What should I do when my Yoshikigoi arrive?

Handling of Koi after transport

You must understand that when transporting the koi there is always some risk.  We routinely  check our fish for parasites and bacterial infections before they leave the farm,however, there is no guarantee that a problem may still occur at some point. You should always keep a very close eye on any new Koi purchased, especially in the first few days after arrival.

When they are delivered to you, it is important to make sure the water temperature in your pond / quarantine set-up is the similar to the temperature the koi have in the bag when they arrive. This prevents unnecessary stress.

We recommend that the Koi are kept in a quarantine set-up initially because they are much easier to observe there. We understand that this is not always possible, but we would like to point out that this is our preferred option.

Handling and management of your koi.

It is extremely important to check your quarantine every day or to closely monitor the pond containing the new fish. In the quarantine tanks , be careful to monitor any water quality issues, particularly rising Ammonia levels. There are suitable test kits available that can measure this important parameter. Ammonia is the most important water parameter and is often underestimated. Particularly with smaller fish, a high ammonia level is usually the  cause of sickness and can  lead to dead fish.

Excessive ammonia levels are extremely damaging to the gill tissue of the fish, so it should not be overlooked and should be measured daily. Failure to do this, allowing  the ammonia to get too high, can cause great damage and lead to possible losses to your fish. It is therefore important to check the ammonia and nitrite values. To avoid nitrite damage to fish and also to relieve the pressure on the osmosis control system, we recommend adding 3 kg of pond salt per 1000 liters of water to your quarantine tank.

What to do if I have problems with my Yoshikigoi?

If you have a problem with your Yoshikigoi, we kindly ask you to send us an e-mail with your question / complaint within 24 hours of receiving the Yoshikigoi. Please also send photo / pictures as this will help greatly .

We will then confirm whether or not this problem affects your problem the right of withdrawal. After reviewing your email, we’ll let you know what the next steps are.

If you are eligible for a refund, we will refund it (less any transport costs) to you within 14 days.
