How long can a goldfish remember something?

Answer 1

A lot of books say 3 seconds, but the truth is...

A goldfish's memory is 11 months long.That is the human equivalent to remembering something for over 40 years. Also, goldfish have been trained to swim through mazes.
Most believe 2 or 3 seconds but it is proven that it is 3 months or so

Look Up comet the gold fish

Proves it is smart

Answer 2

In my experience fish can remember things for several years. A fish will soon learn to recognise the person who feeds it. They will also learn to recognise the different containers that are used for the different foods and will also learn to respond and react to different sounds. During a recently televised controlled experiment using mazes, goldfish were found to be able to learn a way out of the maze and then be able to remember the route through the maze several days later.

Answer 3

Gold fish do not have second long memory spans. They are actually pretty average spans. Goldfish CAN be taught tricks, can learn colours and other strange things. They also live in schools so have to remember who they live with!

Answer 4

A betta fish has an excellent memory span! They can remember for up to 5 months. One of the things I love about Bettas is how they'll remember their owner's face. My bettas flare at anyone that isn't me and I think it's hilarious. The whole thing about how fish have a memory span of 3-8 seconds is a myth that has already been debunked. There was a study where they taught some goldfish some tricks (yes they can learn tricks and so can bettas!), then they didn't do any of the tricks for months. They come back 5 months later and the fish still remember! I think it's really cool. There are other studies than just this one and there was even a Mythbuster's episode about it!

Answer 5

The answer is up to three months. This has been scientifically tested and verified. The '3 seconds' myth is not true.

Answer 6

Betta fish have a memory of approx. 2-3 seconds, depending on their age. It is an unfortunate fact of their lives, but sadly it is true.

Answer 7

the average memory span of a goldfish is about 3 seconds. The reason why goldfish spin around in circles is because everything is new to them!

Answer 8

I know as a fact (from a book) that a goldfish only has a three-second memory. So I never expect my goldfish to recognize me as their owner! =)

Answer 9

Goldfish actually have a memory span of at least three months. They can remember individual humans, shapes and colors, and when their dinnertime is, among other things.
