My koi are moving really slowly, but scatter when I get close to the pond. Is that normal?

When the water gets cold, koi fish get lazy. Okay. Maybe not lazy – but they slow down considerably as their bodies conserve energy to withstand colder temperatures. But despite their natural tendency to slow down in the off season, their survival instincts remain intact. Thus, when they sense motion from the outside world, they get nervous.
As denizens of the deep, it’s only natural for koi fish to assume that everyone out of the water is looking for a quick meal. With that logical perspective, it’s normal for them to demonstrate a brief burst of energy in the interest of self-preservation.
It’s also natural for koi fish to lose their appetite when things get chilly. During the winter months, both their mobility and their metabolism slow down to preserve energy until things warm up in the spring. That’s why we recommend our PondLogic® Spring & Fall Fish Food for the months leading up to winter. This food is designed for easy digestion, and provides healthy nutrition until the water drops below 40 degrees Fahrenheit. After that, koi fish can subsist safely on available organic matter at the bottom of the pond. They’ll eat what they need, and no more, and resume feeding when temperatures climb above 40 degrees again in the spring.
