Fish are brainless?"Remembering after 11 months"

However, a study has been published showing that fish will have long-term memory.
Professor Colum Brown of Macquarie University in Sydney, Australia, recently conducted an intelligence test of goldfish and reached this conclusion, according to British media Daily Star.
For the experiment, he created a miniature model and installed escape routes inside the aquarium showing how fish get caught in nets.
As a result, they found that fish became more and more proficient at figuring out where the way out was.
Brown also found evidence of long-term memory, explaining that he was still remembering the escape route when he put the fish back into the device 11 months later.
He said "By the end of the four or five experiments, the fish were swimming calmly in front of the net installed. And when I got to the middle of the aquarium, I literally made a U-turn and swam straight through the hole."
In addition, it was observed that fish not only recognized each other, but also matched better with familiar fish than unfamiliar fish.
Professor Brown "We can infer that they have some long-term memory by looking at fish migration patterns, spawning behavior, etc"If you didn't have that kind of ability, you wouldn't have survived long in the real world."
He added that "Human underestimation of fish intelligence is seen as a reason to relieve the guilt of hunting or abusing them.'
