How long is a goldfish memory?

THE TRUTH IS

A GoldFishs memory is 3 months long

a long time ago some person made up a myth that golfishs memory were 3 secondsbut then a few scientists figured out that it was 3 months!!
varying from 2 seconds to 12 seconds depending on what type it is

basically not very long

WRONG.

Goldfish are actually more intelligent than we give them credit for. Mythbusters proved this by teaching them to swim mazes and their time got faster and faster thus proving they have good memories
