Koi a foot long in a big pond with ample foliage are very unlikely to
damage lilypads in any numbers, they do little more than suck snail
spawn of plants as tough as those.

Far more likely theres a turtle that wandered in that has taken a
shine to munching on water lily stems and the snails that amble along
them. Check the stems that were severed, look for a distinctive 'v'
shape bite of a turtles guillotine like mouth, if you see those angled
bite marks, it sure isnt koi

I guess I better watch my wording on here, or I'm going to start a panic--I
think there's 6 of them, I started out with 8 a year ago and they were about
2 inches--the water is murky so I didn't see them for 6 months and was
really surprised at the growth to a foot.
