How long is the memory span of a goldfish?

Answer 1

And just look how quickly you get the uninformed answers of X seconds popping out of the woodwork.
Time and time again goldfish have demonstrated the ability to learn, which indicates some long term memory. Exactly how much is not known, but certainly they have long term memories.

Answer 2

Forget the old jokes about goldfish: a University of Plymouth psychologist wants to explode the myth that fish have a three-second memory span. Dr Phil Gee claims fish can remember things for at least three months and can even tell the time - or at least sense what time of day it is.
He said fish can learn that pressing a tiny lever in their tanks can dispense food at certain times of the day.
Dr Gee said: "Scientists have known for a long time that fish, even goldfish, have more than a three-second memory. In fact, research has shown fish have a memory span of at least three months.
"Research has also shown that fish can learn to distinguish between different shapes, colours and sounds."

Many people have never stopped to think about it, but fish are smart, interesting animals with their own unique personalities—just like the dogs and cats we share our homes with. Did you know that fish can learn to avoid nets by watching other fish in their group and that they can recognize individual "shoal mates"? Some fish gather information by eavesdropping on others, and some—such as the South African fish who lay eggs on leaves so that they can carry them to a safe place—even use tools.
