Fish do/don't anticipate things? (was: "ARAs" against Game chickens)

Even the simplest organisms have some capacity for learning when it's
directly related to their survival. If a fish always sees a person when
it's being fed, it will associate the image of a person with food and
will exhibit feeding behavior every time it sees somebody, even before
any food is dropped in front of them. In the wild and in captivity, this
ability to associate events ensures that the smartest fish gets to the
food faster than the dumb ones and is thus more likely to survive longer
to pass on it's "smart" genes.

The only question I have, could such a fish (one having learned to
associate the presence of humans with food) learn to distinguish between
humans and other large creatures who show up in front of it's tank who
don't feed it (like dogs or cats)?
