Called 'goldfish brain', but how exactly is this fish remembered?

Goldfish are a tiny creature, but can they store a large amount of memories inside their brains?

The beautiful gold fish is not the most pet-friendly pet in the family. We sometimes tap branches into their funny round glass tanks, regardless of whether they're uncomfortable or not; we often forget to clean the house for them (when that happens, the goldfish are pulled out of the tank by rough hands and released directly into the sink full of water); and when they unfortunately die, we do not bother to organize formal ceremonies, but just flush them down to the toilet. Wrong, totally wrong to treat such goldfish.

Many people say that goldfish have a bad memory, when their memories are only kept for about 3 seconds.

One of the arguments people often use to make excuses for that heartlessness is that goldfish don't remember how many times they were harassed. Many people say that goldfish have a bad memory, when their memories are only kept for about 3 seconds. But is that true?

According to the Animals page, no one has a definite answer . To prove it, take a look at a study that was done to show that fish memory in general is not as bad as rumors. The first experiment was conducted at the Technion Institute of Israel, where scientists spent a month to "train" the fish to react to an underwater bell signaling food. After 5 months of being released to the sea for development, they are called back by the same signal. That not only shows that fish can develop conditional reflexes, but also demonstrates that their memories can last for months.

But that's fish in general, what about goldfish? Researchers at Plymouth University were interested in finding out how goldfish can learn and remember. First result: Goldfish can be taught to push a lever to provide food (too great for an organism that we still think we can't do much!). But not yet: during the 3-month study, the scientists adjusted to the other lever to work only 1 hour per day. Instead of constantly pushing levers and not getting any food, scientists discovered that goldfish have adapted and pushed levers at a much less frequent frequency during periods of no food. . And they even know to gather around the leverage when the time of food is coming, showing that they remember the time to eat.

Goldfish can be taught to push a lever to provide food.

Another study, conducted by researchers at Belfast University in Queen's, showed that goldfish will avoid hitting the wall of the tank if they are electrocuted in the previous 24 hours, indicating they remember the possible location. The ability to cause pain to the body .

So don't mess with goldfish, rest them!
