Mythbusters spent so much time on this and somehow the myth still persists all these years later.
There's also that team that built a mobile fish tank that the fish controlled, which proved that fish could learn and retain a task.
They taught the using food rewards, then the fish were allowed to just wander around places (although, they had to be supervised incase the drove in risky ways).
The study also showed that some fish (within the same species) were smarter or at least, better at the training than others.
Ironic, isn't it?
It's like rain on my wedding day

Humanity is unable to remember, for any length of time, a fact about whether goldfish can remember things for any length of time.
You are right, that's brilliant!
