It's said that fish have a memory of only 7 second

The popular belief that fish have a memory span of only 7 seconds has been widely circulated, but recent scientific research suggests otherwise. Studies have shown that various fish species are capable of learning, remembering, and even adapting their behavior based on past experiences. For example, research conducted on goldfish demonstrates that they can remember tasks and environmental cues for months, which challenges the notion of extremely short memory. Fish use their memories for survival tasks such as identifying predators, finding food, and recognizing mates or territory. Cognitive abilities in fish are more complex than previously thought, involving spatial memory and social learning. Some species can be trained to navigate mazes or respond to different signals, indicating a memory span that far exceeds a few seconds. Understanding fish memory not only changes how we perceive these creatures but also has implications for animal welfare and conservation strategies. Recognizing their cognitive capacities encourages more ethical treatments in aquaculture and aquarium settings. In summary, the idea that fish only remember things for 7 seconds is a myth with no strong scientific backing. Fish memory is diverse and adaptive, with some species showing impressive long-term memory abilities that contribute to their survival and behavioral complexity.
