I wonder if the differences in behavior we observe may be due in part to what else is in the pond? Theo has CC's I think and I do not. We both have HSB, although I have several and Theo has one I believe. I don't know.

Wish it were possible to do "field trials"..where forum members could go to the other person's place to observe. I would welcome any forum member to my place. I think our ponds have subtle differences such that we could all learn so much more by seeing other ponds in action. If wishes were horses...
