Koi Knowledge
Tips from the experts
Whether you're new to koi keeping or a seasoned collector, these fundamentals make all the difference.
Water Quality is Everything
The saying goes: 'We don't keep koi — we keep water.' Test your pond water weekly for ammonia, nitrite, pH, and KH. Healthy water means healthy fish.
Feed by Season
In spring and autumn, use wheatgerm-based food that's easy to digest. In summer, switch to high-protein growth food. Stop feeding below 6°C in winter.
Quarantine New Fish
Always quarantine new koi for 2–4 weeks before adding them to your main pond. This protects your existing fish from parasites and disease.
Know Your Varieties
From Kohaku (white with red) to Showa (black, red & white) — understanding koi varieties helps you build a balanced, beautiful collection.
