No idea, not sure what eats ground up fish. Might be an interesting controlled experiment for a large aquarium that would allow you to actually see the results. If they didn’t eat it, you would probably have some fouled water.

I doubt that, in small amounts, it would have any type of negative effect on water quality.

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.
