This can make the food to decay in their system and eventually kill them. Besides that, the fish tend to reduce their activity level. When you stop to feed the fish, the pond will be cleaner and there will be less food waste. Since the digestive system of koi fish is twice the length of their body, food digestion can take days.

These are feeding the right foods and feeding in the right amounts. Each time you feed your fish, whether its three times a day or three times a week, you need to make sure you feed only what they can eat in 5 minutes.
A little experimenting can teach you how much to feed. If, five minutes after feeding, there is still uneaten food you know to not feed that much next time. Determining what and how often to feed your fish depends primarily on water temperature. In warmer water degrees the metabolism of the fish is high and they can be fed times per day. At this time you should be feeding a food with a high protein level such as Legacy Variety Mix.
If the water rises to 90 degrees or above you should stop feeding. In spring and fall when your water temperatures fall to degrees, you should reduce feeding to once every days and feed a low protein food such as Legacy Cold Weather Food. When the temperatures drop to below 50 degrees stop feeding the fish.

Ultra Balance notes on their fish food labeling to not feed fish when water temps are below 41 degrees.
Watch your temperature and the fish. During the winter, I measure daily during the transistion period. Your fish will stop eating before that 41 degrees.
Do not put food in when they are not feeding or you will poison your pond. They are in the business of selling food. It is to their advantage that you keep feeding after the fish are dormant. It is also in their brochures and other literature.
Just a few pellets is all they seem to want. I believe what I see. I take daily temperature readings digital thermometer that has been calibrated in my breeding and stock ponds.

People on this Forum rely on accurate information for the safety of their fish and ponds. No matter the advice, or where it comes from, I reccommend to all, to see and check for yourself, when the fish stop feeding, act responsibly.

At this point, staple food is advised as the high protein diet of the summer would be hard for them to digest and a staple is a good way to wean your fish off their high protein diet in preparation for the winter. Autumn Fish Food. During winter your fish will slowly stop feeding as the temperature drops down, once the water approaches 4 degrees centigrade, we advise you stop feeding your fish as the temperature is too low for them to be able to metabolise the food properly and the unsettled food may cause illness in your fish and issues with your water quality.
Winter Fish Food. How much food do I need to feed my fish? Well the simple answer is that it varies depending on your pond. For example, ignoring filter mechanics, say you have a 50, litre pond that spans most of your garden but you only have 4 goldfish and 2 koi in there, you simply won't need to feed as much food as someone with a 20, litre pond stocked with 10 koi and 20 goldfish.
The easiest way to tell how much food your fish need is to feed a little bit at a time and watch them eat. You can then decide if all the fish have eaten and if they need more food. It is important to remember that koi and goldfish are part of the carp family, a fish species known for appetites that are way larger than their bellies can handle, so it is better to underfeed your fish than risk contaminating your water.
