I HAVE Answers

Frequent Questions

Unfortunately, not. Because we are breeding koi we do not unnecessarily net our koi, and this maximises their growth. You can purchase our koi from koi shows throughout the UK.

Yes they will. Mujimono Koi are no different genetically from those that are imported from Japan. The parent koi that we breed from are 100% Japanese and the bloodlines are pure.

With low stocking levels, good quality food and purified water, koi can live upwards of 20 years, maybe even 30 years.

No, we do not ship our Koi at present. If you want to purchase Mujimono koi fish you’ll be able to do so at a live show and the koi are personally and safely shipped there by us.

Orders placed before 2pm are shipped the same day. Orders under 2kg are shipped via Royal Mail, and orders over 2kg will be dispatched via DPD (next working day).

We recommend 1.5 meters or 5 feet as an ideal depth.

Expensive koi food often signifies better ingredients. Protein levels of 36-37% are generally ideal, but higher levels for young koi (tosai) can be beneficial. However, excessive protein may lead to unwanted effects in the water and the fish. Consider the type and quantity of protein when evaluating costs.

The best practice for water testing is a minimum of once per week and continuously thereafter if you spot any issues or when treating the pond.
