Jan,

Thanks for pursuing the article. Lots of good stuff in it.

She is very clear about not liking trout and catfish food. I am sorry
she does not discuss the deficiencies of it any further. I wonder if
they are they as simple as lacking vitamin C or bigger in the
composition of the food.

I don't know that I will move to more expensive food, but I have a
clear vet statement about not liking catfish food.

Now I need to find a supplier like the one that Roy has for cheap koi
food.
