Supreme pondmeister Bob Lusk says that fish become conditioned (such as associating the sound of our footsteps with delicious fish pellets), but they have poor memories. Maybe 15 minutes, that's all.

So as a pond nerd, I ask: What's the difference? If fish don't remember to associate footsteps with food, how can they condition to respond the way that they do?

Is it that memory involves specific images, but conditioning is a more vague "after this, then this other thing which I like" deal? Maybe more emotional than rational?

Purely hypothetical, of course, but interesting.
