“Goldfish have a 3-second memory”
FALSE ✕

TL;DR ·Goldfish can actually remember things for months - the 3-second myth is false.

WHAT WE FOUND

Research has definitively debunked this myth. Studies show goldfish can remember things for months, not seconds. They can be trained to respond to sounds, navigate mazes, and recognize their owners. One study demonstrated goldfish remembering a lever-feeding mechanism for over a year.
