Everyone knows that goldfish have a “three-second memory” don’t they? However, this seems to be a case of bad PR, as it turns out that goldfish can recall things for months or even longer. Goldfish are very intelligent and can be taught tricks that require cognitive ability and to remember sequences that lead to a reward. They can do amazing things such as navigate through mazes, avoid being caught in nets, and then recall these actions months later. Goldfish can even....drive?! Watch on to find out more! #ScienceUnmasked#Goldfish

The secret lives of goldfish. Everyone knows that goldfish have a three-second memory,
don't they? After all, it's a common joke when someone forgets something to tell them they have
a memory like a goldfish, which presumably comes from watching a goldfish in a small bowl going
around and round in endless circles. However, this seems to be a case of bad PR as it turns
out that goldfish can recall things for months or even longer. According to various scientific
research that has been around for past 60 years, it turns out that goldfish are regularly studied
to understand learning across other fish species. Welcome to Science Unmasked. Please subscribe and

2,000 years ago in China for use as ornamental fish in ponds and tanks. They were seen as a
Goldfish are very intelligent and can be taught tricks that require cognitive ability
and to remember sequences that lead to a reward. According to Cullen Brown, an expert in fish
cognition at Macquarie University in Australia, goldfish can do amazing things such as navigate
through mazes, avoid being caught in nets, and then recall these actions months later. Goldfish
can drive. Now, a multidisciplinary team of scientists at the Ben-Gurion University in Israel
have shown that goldfish can be trained to reach a visible target by navigating a robotic system
that turned their fish tank into a fish-operated vehicle. The researchers wanted to test whether
an animal has innate and navigational abilities or if an animal is restricted to its own home
environments. The fish-operated vehicle is a wheeled terrestrial platform that reacts to the
movement's characteristics, location, and orientation in its water tank to change a
vehicle's position in the arena. Each time the fish successfully touched the target,
which is a pink corrugated board on the wall, the fish were rewarded with a food pellet.
The researchers changed the position of the tank, and the fish were able to correct themselves and
change direction to reach the target. The fish were tested 28 times, and the study recorded
the average of their results. Many of the fish went from needing 30 minutes to find the target
to finding it in under a minute. The fish were able to operate the vehicle,
explore the new environment, and reach the target, regardless of the starting point.
All while avoiding dead ends and correcting location inaccuracies, they were not fooled by
false targets placed by the researchers. The research showed that navigational ability is
universal rather than specific to the environment. Goldfish have the cognitive ability to learn a
As anyone who has tried to learn how to ride a bike or drive a car knows,
it is challenging at first. Who would have guessed that goldfish can drive?
The world is full of mysterious phenomena, and science is discovering new things every day.
