I found this forum with Google when I looked up info on the differences between koi food and catfish food. The link was from 2003 and a lot of people seemed to be okay with feeding their koi, catfish food, so I thought I would ask the people who have koi who have been feeding their koi catfish feed; how their koi were doing? Has anyone who has been feeding their koi for years with catfish feed noticed anything unusual, or has it killed any of their fish?

I just discovered a 40lb bag of catfish feed that is manufactured by Cargil and it is about a 1/4 of the price I pay for Rangen... (So, I'm trying it out).
