Do goldfish really have bad memories?

Goldfish remember more than we first thought

For a long time it was generally accepted that goldfish couldn’t remember much about their surroundings and only had three-second memories. However it has since been discovered they can remember more than we thought, especially when compared with other fish. The three-second myth has been debunked numerous times and experiments have shown that goldfish are able to learn and retain information, and even recall the knowledge after a period as long as 12 days. Goldfish have also been trained to press a lever at a certain time of day to obtain food, demonstrating a certain level of intelligence. Your goldfish may even remember you, as there is evidence to show they remember their keepers and are able to have a favourite – usually the person who feeds them!
