I agree unless you are waisting money by feeding expensive foods. Im wondering,,why then,if it is animal fat that is bad for koi, why is corn? I have noted that most koi food has corn meal in the food.

yet I have been told by a guy who sell koi food to stay away for koi food that has corn in the mix. I guess he distributes the brand Show Koi which is what I feed the koi.
