Actually goldfish have a memory span of about 3 months (taken from the book of general ignorace):
What has a three-second memory?
Not a goldfish, for starters.
Despite its status as a proverbial fact, a goldfish?s memory isn?t a few seconds long.
Research by the School of Psychology at the University of Plymouth in 2003 demonstrated beyond a
reasonable doubt that goldfish have a memory span of at least three months and can distinguish between
different shapes, colors, and sounds. They were trained to push a lever to earn a food reward; when the
lever was fixed to work only for an hour a day, the fish soon learned to activate it at the correct time. A
number of similar studies have shown that farmed fish can easily be trained to feed at particular times and
places in response to an audible signal.
