At least three months.
goldfish do have longer than a 3 second memory
The goldfish It is said a goldfish only has a memory span of just a few seconds
It actually has a memory span of a month. I read this in a book. Don't blame me if it is wrong. This is because a goldfish always recognizes it's owner, knows when it should be fed. It only has the attention span of 3 seconds.
They could be seeing themselves in the reflection of the glass of your tank, but since goldfish do not have the capacity to recognize themselves in a reflection they think it is another goldfish and attempt to swim towards it. It has nothing to do with having a short memory span as the previous answer said, because goldfish actually have a long-term memory span of about three months.
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.
Goldfish can only remember the past five seconds of their life.
Yes, but it requires constant bribes, and goldfish only have a memory span of three months. Few people have taught their fish tricks,
their memory span is 10 seconds, i think that by the time they can find something unusual to do they forget it.
Not by itself, no. Though if you're talking about a goldfish or other being with a short memory span then it may be ironic!
Goldfish Memory was created in 2003.
The duration of Goldfish Memory is 1.42 hours.
Certainly not goldfish. That old saying has been proven to be incorrect. Goldfish can easily be trained and simply by comming up to where they are used to being fed indicates that they do have a good memory.
