Studies have found the concept of fish having three second memories is a myth and goldfish memories can last as long as three months.
That fish have an incredibly short memory is known to everyone. Unfortunately, like many well-known "facts", it is not true.
Goldfish three-second memory myth busted
Three-second memory myth: Fish show they can remember things for up to five months
Modern myth would have you believe that goldfish can't remember anything that happened more than three seconds ago …
In fact, goldfish have been trained to navigate mazes, and after a few months, a goldfish can recognize its owner.

… The popular myth that goldfish have such short memories that they forget they have already been on one side of their fishbowl by the time they have returned seconds later is not true.

Minne som en guldfisk behöver inte vara det sämsta att ha. Glöm myten om att fiskar bara minns de senaste tre sekunderna! De kan exempelvis memorera den rätta vägen i en labyrint och har visat sig vara bra modeller för minnesforskare.
Goldfish brain slur is myth as scientists discover they have long-term memory
Guldfisk har en glimrende hukommelse
Ny forskning visar dock att vi borde vara tacksamma över att bli jämförda med guldfiskar – de har nämligen bättre koncentrationsförmåga än oss människor.- Café, 13 januari 2016
It turns out that there is no evidence that goldfish – or fish in general – have particularly short attention spans or memories, despite what popular culture suggests.
Despite the enduring “three-second memory” myth, even goldfish—which can live up to 40 years—can recall exact colors and locations of specific feeding tubes up to a year after exposure.
… The humble goldfish may not only have a longer memory than most people think, but may also be far smarter.- University of Melbourne, 27 oktober 2019
The myth is that a goldfish's memory lasts about three seconds. This has been repeatedly debunked.
The goldfish were not in the least discombobulated, easily adapting to the new regime and only bothering with the lever at the right times of day. Clearly, goldfish are smarter than they are given credit for.
Har guldfiskar verkligen dåligt minne? Svaret är: nej.
