Many people believe so, but it has recently been challenged by the Myth Busters, who were actually able to train their gold fish, which would prove that they indeed have memories longer than 3 seconds.
It was two to three minutes.
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! =) Despite popular opinion that goldfish have no memory it has been show in many studies they do have long term memories. It is generally accepted be around two week but some studies have shown it to be up to 11 months.
Auditory images typically last for a few seconds to up to 4-5 seconds in sensory memory. However, this can vary depending on individual factors like attention and the complexity of the sound.
Short-term auditory memory typically lasts for a few seconds to a minute, in which the brain temporarily stores and processes auditory information. Long-term auditory memory, on the other hand, can last for years and involves the storage of information for a longer duration.

To the best of my memory John and Mary have never had a cross word.
Short-term memory is memory that only holds a few items of information. It does not last long, so it must be rehearsed in order to be encoded into the brain for storage. Most of the time-it lasts up to 18 seconds.
A minute and 30 seconds are equal to 90 seconds.
actually, a bird memory can last up to 2 years...a bird has a very good memory and it can last even longer if it has been trained :)
