　　If you think that fish have poor memory, please think again. According to the findings of scientists through animal experiments, fish can learn food 12 days in advance.

　　Canadian researchers trained fish to find food. They were caught from the tank for 12 days. When the fish re-enter the aquarium, they can find out the location of the food through surveillance and tracking software. The focus of this research is on African cycloid, a popular tropical fish that has previously exhibited complex behaviors, including aggressiveness.

　　Researchers believe that African cycloidal animals can perform advanced memory tasks. After training, each fish can be transferred to a special location in the aquarium to eat. Each training lasts 20 minutes. Three days later, Cyclid in Africa stopped eating for 12 days and introduced him to a special place in this aquarium. Their activities are recorded by motion tracking software.

　　The software system shows that African one-eyed animals can return to the aquarium to find a special place to eat. Scientists believe that the African cycloid needle can recall previous training experiences. Dr. Trevor Hamilton of McVin University said: "There is a lot of discussion about the wisdom of fish. Some people think that cyclophosphamide is watching TV. If you can go back to the previous feeding position, you will get food. Reduce the possibility , It improves the survival ability of fish so that they can remember the source of food."

　　The food types of wild bicycles include cattle, small fish, insects, and plants. relative position. Dr. Hamilton is currently investigating and analyzing whether fish memories are affected by environmental conditions and drugs.
