Scientific studies have demonstrated that pet fish remember things much longer than three seconds, as the common myth suggests. Some think we only tell ourselves fish have short memories to justify placing them in small, otherwise empty tanks with little to stimulate their minds. But researchers around the world have found that goldfish and other fish varieties can be trained to swim through mazes, respond to light and sound cues, and return to a food source at the same time each day. Instead of three seconds, goldfish memories can last at least three months.
