? The saying about the seven-second memory of goldfish is a rumor that has arisen at an unknown time. In fact, although the memory of goldfish is not particularly long, it is generally about 1-3 months, and some species can even remember longer. For example, goldfish can remember their mothers and learn how to survive in dangerous environments, which can not be accomplished by seven seconds of memory. When we feed goldfish daily, we will also find that when we feed fish regularly every day, after a period of time, the domestic goldfish can even remember the owner, when the owner feeds the goldfish, the goldfish will take the initiative to approach.
on Goldfish Memory The study of goldfish memory began as early as the last century, and there are many experiments on goldfish memory. Experiments on goldfish memory are described in books such as Fish Cognition and Behavior. The experimenters put two tubes of different colors in the goldfish's feeding tank, one of which has food, and the goldfish can only eat if they choose the right color. After training the goldfish for a period of time, the experimenters removed two tubes. A year later, the experimenters put two more tubes into the fish tank, and the goldfish could still quickly choose the right color tube to eat. This shows that goldfish have a long memory, far more than seven seconds.
