Goldfish Memory Lasts Months, Not 3 Seconds

The myth that goldfish have 3-second memories is completely false and has been thoroughly debunked by scientific research. Studies show goldfish can remember things for at least 3 months, and possibly much longer. Researchers have successfully trained goldfish to navigate mazes, recognize different shapes and colors, perform tricks like swimming through hoops, and even play soccer. Goldfish can distinguish between different people and often get excited when they see their regular caretaker. They learn feeding schedules and can be conditioned to respond to different sounds or lights. Some studies suggest goldfish may have memories lasting up to 5 months. Their ability to learn and remember is so well-established that goldfish are now used in behavioral research. The 3-second myth likely persists because it justifies keeping goldfish in small, boring environments.
