What I _will_ say as a blanket statement is that, in a fish pond, lilies can
get all the nitrogen they need from fish. I'm well aware that plants need
more than nitrogen. If your plants don't do well enough bare-root, then
the answer is still not to plant in compost. Plant lilies in clay - then
you can use fertilizer spikes without most of the nutrients migrating into
the water.

Your plants may grow just swell, but that's not the same as "they
get everything they neeed". You can prove this by fertilizing them
and observing more and more vigorous growth. Until then you're just
guessing, not stating objective fact.

Your opinion is just that and should not be passed off as factually
correct.
