How To Help Your Koi Fish Survive Winter
You can help your koi fish survive winter in a few ways. Pond fish in winter need a hole in the ice, an aerator, not to be fed below 50 degrees Fahrenheit, and a clean pond. Ponds in Maryland over 2 feet deep won’t freeze all the way.
When winter comes your fish do like bears and start to kind of hibernate. They’ll just kind of float around in a half-asleep state.
Koi fish in winter are half-asleep and so are their bodies. Feeding them during this time can cause them to get sick and even die. The food they eat basically sits in their bodies and decays. This is why people don’t feed them when it hits 50 degrees Fahrenheit. When it gets around 60 degrees Fahrenheit you can switch to cold water food.
You’ll want to winterize your pond too:
Speaking of decay, anything left in your pond over winter will. Leaves, grass, debris, and other stuff will break down over winter. It turns into sludge and releases gas. This makes your pond nasty and can be bad for your fish if there’s not a hole.
Having a hole in the ice allows gas from decaying matter and your fish to escape. It also lets oxygen in so your fish can breathe.
Do not break a hole in the ice. Pond fish in winter are already half-asleep and this could scare the life out of your fish. Literally. Instead, use a de-icer to create a hole. You can also leave your waterfall running to create a hole. A third option is to move your aerator nearer the surface.
Well, you should move your aerator closer to the surface anyway. It oxygenates the water by moving it around. Your fish stay near the bottom because it’s warmer. An aerator near the bottom will push warm water up and cold water down. Your fish would be cold all winter…
In summary, you can help your koi fish survive winter by:
- Not feeding them under 50 degrees Fahrenheit
- Clean your pond before it freezes
- Create a hole in the ice, gently
- Move your aerator closer to the surface
