I might have to amend that statement. The nematodes don't like being in the water because they drown. When you see them under the scope they thrash around. I have seen one or two feeding, but mostly thrashing. I'll bump this up to the top and see if Tim Wilson responds. I believe he's looked at nematodes under the scope a bit.
