Goldfish for a long time has been associated wit very high levels of memory loss and as such there are suspicions that the precious fish memory lasts up to two seconds after experiencing a event.
It is ids due to this flash memory loss that the common saying "as forgetful as a goldfish" was excerpted from long ago.
If u dint know, now you know
I have 18 goldfishes that I have been taking care of for long time now. They have very good memory where they always know where the food is being dropped from or who is the person that feeds them.
I guess it may depend on which goldfish you talk to :)

How many are there?
This association is a myth, thankfully the fishies have decent memories.
A scientific myth i guess
