>The nematodes also come with the lake water?

In our hydrae experiments, yes, they came with the lake water .. you can see some pictures here if you're interested, there's a video of the battle between nematode and hydra as well - I did this experiment with my kids many times over the years, its always fascinating to see what grows and what eats and what stays behind ..
