Considering that eels and salmon can return to their birthplace after spending years in the sea, it would be remarkable indeed if their cousins had no memory. And anyone who has fished for big carp with a rod and line will know that they can display as much cunning and sensitivity as a dog.

Fish are pretty canny, in my experience.

With a memory which only lasted seconds you wouldn't know where food could be obtained, or be able to differentiate friend from enemy. So if a species of animal with such a short memory has ever existed, natural selection would dispose of it promptly.
