What You Should Know about feeding your koi
Having a pond might be a good idea, especially one that’ll be booming with life. However, you can’t ignore having to feed your koi with proper koi food. With koi being a popular choice for any pond, what most people don’t realize is that they need to be fed regularly. Thinking that your koi will find enough food to eat from the wild in the pond is wrong. You’ll need to make an effort to feed them.
Everything you need to know to properly feeding koi is set out below.
Koi belong to the carp family, which means that they are omnivorous and can eat various kinds of food. However, feeding your koi involves more than just the food they eat. Here is a guideline of how much, when, and what to feed your koi.
Factors affecting feeding koi
There are various factors that you should take into consideration when feeding koi. You can’t just throw food in the pond thinking that your beautiful fish will eat it when hungry. You need to be aware of the food quality you’re giving, the temperature of the water, and the overall environment of the pond among other factors.
1. Food quality
The quality of food that you give to your koi plays a vital role in the rate of their growth as well as their well-being. This means that feeding your fish, food that isn’t high-quality will eventually make them ill. On the other hand, giving koi good quality food of , which a lot of pets shops have available, will have a positive effect on not only their body weight but also on the color and vibrancy of your fish.
Which foods are suitable?
Koi welcome various kinds of live foods which include worms as well. You can easily feed earthworms to your koi throughout the year. Worms contain a high amount of protein and are a favorite of omnivorous fish. You can also go green when feeding koi.
These ornamental fish will eat lettuce leaves as well as the flora present in and around the pond, such as duckweed.
You might want to throw other food to them such as pieces of bread. Koi will usually eat most types of food thrown in the pond to them; However, most of these food have little or no nutritional value for them and may even harm your fish.
You can feed your fish brown bread but not white. White bread is made using mild bleach; So do not feed your koi white bread.
Koi also eat foods like corn, beans or peas which have a shell-like skin. However, this skin will lead to your fish experiencing irritation as digesting the shell is difficult for them.
2. Temperature of the water
The water temperature determines the amount of food your fish eats as well as the frequency with which it eats. If you try to feed koi during winter, when the temperature of the pond is low, at the same rate with which you fed them during the warm summer months, you’ll end up harming them.
The digestive system of koi is dependent on the temperature of the water they live in. In cold temperatures, their digestive system slows down and even stops when the water is cold enough.
As the temperature of the water starts to fall, the level of protein that you mix in the feed should also be reduced. This change will not only help to make digestion easier for your koi, but will also help to avoid waste.
Similarly, as summer arrives and the temperature of the pond starts to increase, the protein in the feed should be increased because the metabolic rate of your koi will speed up. Therefore, a higher amount of protein will be needed for proper growth as well as for maintaining their health.
As mentioned, the temperature of water not only governs the kind of feed that one should use, but also the frequency at which the fish should be fed. When the temperature is low, feeding koi only once a day will be enough. On the other hand, when the pond’s temperature rises, koi can be given food every hour.
How much should you feed?
Of course, the amount of food as well as how often koi should be fed is debatable. However, a general rule is that when the water is around 58-Farenheit or below, then the protein level of your feed should be below 38%. When the water temperature falls below 46-Fahrenheit, you should stop feeding altogether.
Similarly, as the temperature of water rises, the amount of protein in the food, as well as the number of times you feed your fish in a day, should be increased. During the high-temperature summer months, the amount of protein in your feed should be somewhere in the forties and the number of times you feed the koi can rise to eight times per day.
Keep in mind that the fish should only be fed for a maximum of five minutes per one feeding. In the case where the fish doesn’t come up to devour the food, then this is an indication that the fish is either too warm, too cold or are not feeling hungry for some reason.
So, make sure that you feed light. If your fish are eating like they haven’t been fed for years, then you can just sprinkle food lightly on the water for a few minutes as long as you can see fish coming up to eat the food.
3. Quality of water
The quality of water has an effect on the growth rate of your koi, because in poor water quality your fish may lose their appetite and won’t eat the food provided. They might even stop feeding altogether. Moreover, poor quality of water negatively affects the metabolic rates of koi, hindering their digestion process.
Furthermore, the stocking level, which is the amount of koi you have in the pond, also affects the behavior of the fish and the way it grows. This means that you should have such an efficient filtration system which can easily cope with the increased amount of waste produced as your fish continue to eat and grow.
If your filtration system is not sufficient for the number of fish in the pond, then the quality of water will be significantly affected, which in turn affects the amount of food that the koi takes in.
More factors you need to consider
There are two more things you need to take care of when feeding koi. One is the digestive system of the fish and the second is overfeeding.
Digestive process of koi
The gut system of koi is a very simple one. They only have a long straight intestine through which all their food passes. The nutrients are extracted from the consumed food when it passes through their intestine. Therefore, your koi can only digest a small amount of food at a time. The amount decreases even more as the temperature of the water decreases.
Therefore, it is vital that you feed fish the right amount of food and a sufficient amount of protein to make sure that they extract the maximum nutrition from the food while also avoiding the possibility of over feeding.
Perhaps, overfeeding is the most common mistake people make when it comes to feeding koi. One reason behind this is the fact that feeding time is the most enjoyable time that you have with your koi. During feeding, the koi come towards the surface to eat. At this time, you can not only see them eat, but can also interact with them. Seeing your fish gather near you while you feed them can make for an enjoyable experience. And they will become tame to you through continued feeding.
Overfeeding refers to any period where the fish eat more than the amount of food they require. This has adverse effects on your fish. An excessive amount of food can lead your fish to become sick and the increased amount of waste that the koi would have to produce causes the quality of water to decline exponentially.
Moreover, if the fish in your pond are fed an increased amount of food, then they develop huge pot bellies, and they start to resemble tadpoles because of their wispy tail and big body. Of course, this does not kill the koi; however, it does severely affect the internal organs such as the liver, and the natural beauty of these creatures.
When you feed more food than your koi can eat then this will stay in the water and pollute the water causing pollution which may make your koi ill. If you can remove any uneaten bits of food five minutes after feeding then you will save your fish any stress from rotting fish food.
Want to feed your koi from your hand?
Koi can enthusiastically learn to eat out of your hand. Once the fish get used to the idea of you being close to them, then you can bring some koi cookies or bread as a treat in an attempt to bring them even closer to you. You only need to dangle your hand filled with tasty treats in the water for them to come to your hand.
However, this task takes time before your koi become tame enough. It may take weeks or months before one of your brave koi to make its way towards you to enjoy the treat from your hand. It will take further time for the others to catch on to the same routine. Soon, the other koi will also be swarming towards your hand in search of the delicious treat.
If you take it slow, the koi might be able to be okay with an affectionate rub and even a pat on their head! That is how tame koi can become. And they may even just come to your hand even when you don’t have food for them.
