I read their FAQ Section. They recommend that one of their protein blocks not be fed to sheep because one of the ingredients, copper, isn't right for sheep. If it's put together specifically for cattle, I don't believe I would feed it to my fish. There are too many unknowns.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Without a sense of urgency, Nothing ever gets done.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP
