We have previously discussed how the environment in which you keep your Koi can affect their size and general health. Here we will discuss how the quality and quantity of food you feed your fish can also have an impact.

Koi food quantity and quality

Both the quantity and quality of food that you feed your fish can really have an impact on their growth and health. The best quality Koi foods should be approximately 40% protein based and be balanced so your fish get the right quantity and types of nutrients that they need.

The quantity of feed you give to your fish can be worked out by the amount of fish you have in your pond and an estimation of their overall weight. If you are looking to increase your fish’s size then a good guide is to feed approximately 6% of the total fish weight in your pond in food. However, if you over feed your fish, the fish may lose their physique and actually get ‘out of shape’. You should also always take into consideration the air and water temperature when feeding your fish. A good Koi keeper will get to know their fish and hence know how much to feed at different times of the year.
