As I understand from those with more experience, the very essence of
object-oriented programming is sitting around a table bickering about
which behaviors should be in which classes...

In our fish models, the fish asks the space for a list of cells within a
certain distance and then the fish evaluates the cells and decides which
one to move to. To me, that's a better metaphor for what happens in real
fish...and that metaphor is the best guide for designing the software.
