When the temperatures in your koi pond or tank are between 52 and 60 degrees Fahrenheit, you will want to feed your koi an easy to digest food such as one made of wheat germ.You need to change his diet because his digestive system will not be moving very well.upiterimages/Photos.com/Getty Images. As a koi owner, it is crucial that you keep your koi's tank or pond at a reasonable temperature. Koi rely on the water temperature to assist with their digestive process and cannot digest food if the water gets too cold.
To determine what, in my opinion, is the maximum safe fish load for your tank or indoor pond, divide the total gallonage by 100. The result is the number of 12-inch koi that can be raised in that volume of water. For example, if you are using a 125-gallon tank, then the safe fish load would be 1.25 12-inch koi.In other words, one 12-inch fish would be fine, but two would be overcrowding.ost common fish health and aquarium/pond maintenance problems can be traced to the unfortunate habit of keeping too many fish in too little water. Consequently, during the past several years I have devised a rule of thumb for determining the maximum koi fish load for a given volume of water (aquarium or pond).
