What eats a water soldier?

Answer 1

Water soldier (Stratiotes aloides) is a floating aquatic plant that is primarily consumed by herbivorous animals such as certain species of fish, particularly carp and goldfish, which may graze on its leaves. Additionally, some waterfowl and other aquatic birds may feed on the plant. Its tough, spiky leaves can deter many herbivores, but those that do feed on it often do so selectively.
