Are there any animals that are known to eat Aldrovanda? I started an aquatic plant container recently and today found most of the Aldrovanda missing, a clump of Utricularia that looks like it has been teased apart, and quite a lot of animal poop scattered near, and in the water. It certainly is a discouraging start to aquatic plant cultivation, especially when I was able to get ahold of red Aldrovanda for it.
