Kois are friendly fish, and koi are valuable fish. Of course, these little darlings deserve only the best feeding. A small overview of the feeding of the Kois and the feed types available:
How often does a koi have to be fed?
A Koi is an omnivore. So, like us, it eats animal and vegetable food, and for the koi's body, too, there is an optimal combination for a healthy diet. It starts with thoughts on the frequency and amount of feeding:
If the Koi is allowed to live in an environment that suits their natural environment, it will live in quite warm water during the summer and then need a nutrient-rich feed. The koi is native to any mild waters, generally eating between 7 and 30 degrees at any water temperature, but the digestive system is most active at temperatures of 23 to 26 degrees. If it gets warmer or colder, the digestive capacity decreases, then the amount of food must be reduced. This is often ignored, many Kois have already died of overfeeding, probably never starved. The amount of food should therefore be measured carefully.
How often you feed is therefore dependent on the water temperature; the deciding factor is the lowest measured value. Since Kois have no stomach, they can not stockpile, they need at the right intervals small amounts. Even if excretions swim on the water surface after feeding, you have caused feeding through the indigestion in Koi, the amount of food should then be reduced.
Attention: overfeed risk
So you do not overfeed your koi, you should first note the following rule of thumb: Smaller koi always get as much food as they can eat in 5 minutes. Medium-sized Kois may take 10 to 15 minutes with their meal and big Kois 15 to 20 minutes.
It is difficult to set the ideal amount of food when small koi and large koi are kept together in a pond. Small kois eat more than big kois in relation to their own body weight, they also eat faster. You can not do much more with such a mixed-occupied pond than calculate the daily amount of food after you determine the optimal amount for the total weight of all fish and divide that amount by the number of feedings.
In summer, the Kois should get at normal temperatures every day about 1 to 2% of their weight in food and also eat. If they do not, if they suffer from loss of appetite, then the quality of the water should be checked. In addition, the Kois need a quiet environment, so they can eat in peace. It is important in any case that at lower water temperature, the amount of food is reduced and fed less often.
If the water is below 10 degrees, the Kois will not get any food at all, between 10-13 degrees they will be fed once or twice a week, from 14 degrees two to three times a week, from 16 degrees one to two times a day, from 18 degrees two to three times, from 20 degrees you get 3 to 4 meals, from 23 degrees 5 to 6 and from 26 degrees then again only 3 to 4.
What does a koi eat?
For the Kois, commercially available food is offered, which is supposed to provide an optimal nutrient balance. There are various shapes for fish of all sizes, powder as baby food, crust for juvenile fish and pellet for the adult fish. This food is sold as a floating food or sink food, for the garden pond, the floating food is usually chosen, the Kois should indeed be observed during feeding.
Mostly the food is dried to a water content of about 10%, quite new is now also offered vacuum-packed food. Whether this is a good idea or just a senseless freshness to the consumer, depends on the ingredients, in any case, you must pay attention to the durability of this food and quickly use open packages. The food is usually composed of:
- about 30 to 40% crude proteins,
- 5 to 8% crude fats,
- 3 to 4% raw fibers
- and about 10% crude ash.
Anyone who knows a little about nutrition, will immediately shy away from the mention of wheat germ and skimmed milk, that's certainly not what a koi eats in natural waters. This is how it is, especially the carbohydrates in their given form and quantity are not only of little interest in koifood, but are also associated with frequent inflammations in Kois by experts.
Best composition of Koi food
According to the current state of science, a feed with 41% crude protein content and 21% crude fat is ideal for Kois.The fat is needed to use the protein. If it gets too low in fat, the fish uses larger amounts of protein to cover its energy needs, releasing ammonia, which can be deadly to pond water and fish.
A fish food with such a composition is rarely offered in the trade for consumers, only if you could switch to professional fattening feed or look around the Internet, you could find a suitable feed. Koi Landau from 76829 Landau in the Palatinate has z. B. Koi Balance, a year-round feed that has been compiled according to scientific considerations.
However, you could also make your own Koi food after informing yourself. Kois eat a lot of things under natural conditions that you can buy in any grocery store or already have in the pantry or in the fridge. There is also a lot of koi food in the garden. Not for nothing the fish with the wide appetite are also called the Pigs, most Kois even have their favorite food that you could explore with their own preparation of food.
