I never had too much trouble with koi bothering the hardy lilies but forget
the tropicals. Once they discover the tubers on them, they will never leave
them alone. They love eating those tubers. Mine have moved huge rocks on
top of the baskets to get these tubers.

Me, too, Joe.... I have 4 koi that are all over 12" long, and they don't
ever intentionally bother the plants. They knock a few around during
spawning, but nothing that can't be corrected. Guess I, too, have polite
fish.
