Great video showing how a goldfish helps a sick friend survive. The owner of the fish noticed that the two of them had difficulty moving around and wondered how they survived for so long.

He decided to film the secret life in the aquarium and fix the secret. The video surprised him… A goldfish was helping his sick friend reach for food floating on the surface.

It is not clear what was behind the seemingly fish-friendly behavior. One thing is for sure: with the advent of new scientific research, we have come to the conclusion that these animals are much more complex than we thought.

Jonathan Balcombe, director of the Humane Society’s Institute of Science and Policy for Animal Intelligence, writes: “As a biologist specializing in animal behavior and sensitivity, I have spent the last four years studying the inner life of fish.

I have found that we underestimate this amazing variety of marine vertebrates. The accumulation of evidence leads to the inevitable conclusion that Pisces believe and really feel.”
