Mark if I had tons of koi to play with, I would do this, but I dont and dont want to lose any of my koi. So the best bet for me is to stick with the koi food. The bag of catfish foods going to the catfish. I dont want liver damage in my koi. That is all I wanted to know, I have eye witnessed this in goldfish and I did not want to do this to my koi if they cant take this type of food. Thanks you guys for the help
