I think it could interfere but maybe from a different perspective. Dye can prevent sunlight penetration and thus inhibit plankton creation. As the base of the food chain, plankton is the food for small (real small) insects that feed the fry. With limited groceries available, all fish recruitment could be adversely affected.

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.
