Do goldfish have a bad memory? How many seconds does a goldfish remember?

The Sunday Times reported that veterinarians hope that goldfish owners must treat their beloved pets well, because the latest research has found that goldfish have good memories, they can feel pain and joy, and when their owners leave, they also want their owners to come back soon.

Previous studies concluded that goldfish only have a 3-second memory, but now researchers have found that goldfish have a very long memory. Raymond Lowe, a veterinarian from Australia, said: "People must think this statement is very strange, but goldfish owners and all veterinarians need to re-understand and take goldfish seriously.

At the Australian Veterinary Association conference in Hobart, Tasmania last week, Lowe presented his findings.

A study cited by Lowe was conducted by scientists in the United Kingdom, who found that at special times of the day, goldfish were able to learn to push the lever to find food. In another study, two goldfish that had fought were placed in the same tank as the other goldfish, and for a long time, the goldfish that had lost the battle did not dare to approach the winning goldfish, apparently fearing being attacked by the winning goldfish.

The studies also found conclusive evidence that goldfish's brain structure makes them feel painful and that they are able to avoid danger that will harm them. Lowe and his colleagues wrote in their ** "Ornamental Fish: Making Fish Smile, Sing, and Dance":

Experiments on goldfish have shown that goldfish have the ability to remember the information they have learned, and they have logical responses, which shows that the fish have memory. "We want to tell people that they care about how goldfish feel, just as they care about other animals," Lowe added. ”

It is said that you can only remember seven seconds, and after seven seconds you forget.

Goldfish memories can last up to months.

The average goldfish has a memory range of about 3 months, while it is generally believed that the memory of a fish is only 7 seconds. In fact, the memory of real goldfish is very amazing, they not only have a super long memory time, but also have a very strong memory ability, and can remember very complex things. Experiments have shown that by using multiple buoys to mark the method of sprinkling fish food, it has been found that goldfish can remember which food has buoys, and when the buoy has no food, the goldfish will immediately go to the next buoy position to eat the food.

Generally, the memory duration of goldfish is about 3 months.

This study actually began as early as the 60s of the last century, because there were rumors that the memory of goldfish was only 7 seconds ago, so in 1966, scientists in the United States began to study the memory of goldfish, and the memory of goldfish was at least 3 days or more.

Scientists have found that fish are more "intelligent" than humans think, and their memory can reach months or even years instead of seconds. They are also capable of learning and using deception to hunt for food.

The habits of goldfish

Generally speaking, goldfish grow and develop very quickly, and after half a year, they are sexually mature and can reproduce offspring. Goldfish are not strict about the required environmental conditions. Under domestic conditions, even at a depth of 30 cm, it can be injected into a smaller aquarium of about 50 liters, and if the stocking density is appropriate, it can mature and reproduce offspring.

There are 3 main factors that affect the speed of goldfish development and the maturity of sexual function, namely nutrition, water temperature and date. In the daily feeding management, it is necessary to pay attention to keeping the water fresh, the bait is nutritious, palatable, and properly fed, especially before winter, it is necessary to consciously and appropriately choose the bait with high protein and fat content.

Goldfish have a memory of up to 1 to 3 months, and it is because of their better memory that they are able to remember their mothers and understand how to survive in dangerous water. As long as they are fed on time every day, domestic goldfish can always remember their owners. And fish, like people, have emotions, and memories change with age.

Goldfish's memory is not only seven seconds, according to scientific studies, with proper training, goldfish's memory can reach up to a month, and up to three months.

The memory of the fish is not very long, but it is not very short either. It is because fish have a long memory that they can remember their mothers and know how to survive in dangerous water.

If it is a domesticated goldfish, they will know their owner, and as long as the owner feeds the goldfish every day, they can always know their owner until they leave this world.

Goldfish, like humans, also have emotions, and when they are angry, they will fight. Some fish's memory is also the same as that of humans, which slowly weakens with age.

The memory of a goldfish can be up to a month.

Fish memory is much more than 7 seconds, as early as the 60s of the last century, when chemistry began to intervene in neurobiology, there were already people studying the memory ability of goldfish.

In 1965, researchers at the University of Michigan in the United States conducted an experiment in which goldfish were placed in a very long fish tank, and then the researchers shot a bright light at one end of the fish tank, and after 20 seconds, released an electric shock at the same location.

Soon, goldfish develop memories of electric shocks, and when they see light, they quickly swim to the other side of the tank to avoid the electric shocks before they are released into the water. Scientists have found that with proper training, these goldfish can have memories for up to 1 month.

1.The "goldfish three-second memory" claim circulating on the Internet is false.

There are many people on the Internet who believe that goldfish only have a three-second memory, which is a false statement. Goldfish actually have a relatively good memory, able to remember some simple things and patterns, such as their owners often feeding and so on.

2.The memory of goldfish is related to the environment and reproduction.

The memory of goldfish is related to their environment and physiological condition. In the natural environment, goldfish living in water with different flows and temperatures have different survival skills, so they need to store a lot of information to cope with different living environments.

3.The reproduction of goldfish also affects their memory.

The physiological process of goldfish reproduction can also affect their memory. During breeding, male goldfish secrete a hormone that makes them more aggressive, while female goldfish may lose some memory of their environment. Therefore, when raising goldfish, it is necessary to pay attention to their physiological state to maintain their health and memory.

4.Goldfish are animals with the ability to "remember for a long time".

Although goldfish have short-term memories of only a few seconds, they can form long-term memories through repeated learning. For example, when you feed goldfish at the same time every day, they will remember and stay at that point in time waiting for you to feed them.

5.Goldfish's ability to learn is also limited.

On the other hand, goldfish have a limited ability to learn. They can only recognize some very simple patterns and shapes, and for complex tasks and activities, goldfish are relatively poor learners.

6.Provide an adequate environment for goldfish to create a better quality of life.

Although goldfish's memory and learning ability are limited, we can enhance their survival ability and enhance their quality of life by creating a suitable environment. For example, providing goldfish with adequate swimming space, suitable water temperature, adequate food, and good water quality are all important for goldfish to survive and thrive.

7.Conclusion.

Although "goldfish three-second memory" is a wrong statement, goldfish's memory is indeed limited. In order to maintain their memory and health, we should provide a good living environment for goldfish and pay attention to their physiological state. This allows the goldfish to enjoy their lives in the ponds we raise.
