✗ The myth everyone repeats
Kids believed goldfish had essentially no memory, existing in a perpetual present moment where they forgot everything every three seconds.
✓ What is actually true
Goldfish can remember for at least three months and possibly longer. They can recognise individual people, learn tricks, and remember feeding schedules. They can distinguish colours, shapes, and sounds. The three-second memory myth likely originated from misunderstandings about fish brain size and a 2000s internet meme. While goldfish aren't as cognitively complex as mammals, they're far from memory-less.
