Why a Slow Start to the 2026 Koi Season is Good for Your Fish

As we move into April, we’re all looking at the sky (and our pond thermometers) waiting for that consistent shift into double digits. While the British spring is taking its time to arrive, things are far from quiet here at N-Koi.

Patience is a Virtue in Koi Keeping: It can be tempting to start ramping up feeding or looking for new additions the moment the sun comes out for an afternoon. However, the “transition period” between winter and spring is the most critical time for fish health. While the water remains a bit chilly, we are focusing on steady maintenance and monitoring.

What’s Happening Behind the Scenes?: Neil has been busy in the tanks, ensuring that every fish – from our standout Kohaku and Sanke to our latest Showa arrivals – is transitioning safely. When the water temperature fluctuates, a koi’s immune system can be slow to react. By keeping a close eye on water chemistry and health now, we ensure that when the season truly “pops,” these fish are in peak condition for their new homes.

A Diverse Selection Ready for Spring: We have a fantastic variety of Japanese Koi currently maturing in our systems. We also have a stunning selection of Koi Carp, Butterfly Koi, Sarasa Comets, Yellow Comets, Shubunkins and Mixed Fantails. Each fish is being given the individual attention it needs to ensure it is robust and healthy before the spring rush begins.

Visit Us While It’s Quiet: The benefit of a slightly slower start to the season is that it’s a perfect time for a more relaxed visit.
