FALSE

Multiple scientific studies and experiments have conclusively debunked the claim that goldfish possess only a three-second memory 1 5 8. Research indicates that goldfish are capable of retaining information for weeks, months, or even years 4 5 9. They demonstrate complex behaviors such as navigating their surroundings, recognizing music, and telling time 1 2 11. The three-second memory idea is a common misconception rather than a biological reality 8 10 12. Experiments show they can be trained to respond to specific stimuli and remember those behaviors for at least three to six months 4 11.
