Goldfish Three Second Memory Alb
Lora Ceasor
Brown has studied the intelligence of fish, including goldfish, for more than 25 years and thinks the misconception comes from a combination of ignorance about fish intelligence in general and guilt, because pet owners often keep them in small, boring tanks.
In reality, goldfish have such impressive memories, they're often used as a common model for studying memory and learning in fishes, Brown said. As a result, "there are thousands of studies [on goldfish] that show fish have excellent memories," Brown said. "And the rate of which these studies are being published is growing exponentially."
A majority of these studies involve food. For example, if goldfish are fed at only one side of their tank, they will quickly learn and remember to stay on that side of the tank at feeding times, regardless of whether they are actually fed, Brown said. Similarly, if pushing a red paddle gains a food reward but a blue one doesn't, goldfish quickly learn to push the red and not the blue, and will continue to show a preference for that color long after the experiment is finished. These types of experiments have also been replicated with other cues, such as bubbles and even music, Brown said.
On top of these findings, there is a wealth of anecdotal evidence from goldfish owners who often observe complex behaviors in their pets when interacting with them. Some even claim that their goldfish can recognise them apart from other people.
It is hard to pinpoint an exact time span for goldfish memory, given that different memories are more notable than others. You're more likely to remember a scary event, for instance, than a mundane one, Brown said. But whether goldfish memories last days, weeks, months or years, it's safe to say they definitely last longer than 3 seconds.
Most people do not come across live fish in their daily lives, and even when they do, "people don't interact with fishes the way that they do [with] other animals," Brown said. This makes it easier for misconceptions and myths to be widely accepted, he said. Public perception of fish cognition may be improving, however, as more wildlife charities and nongovernmental organizations spread the word about fish intelligence. "It's changing more rapidly now than it was than it has done in the past," Brown said. "But it's still slow."
Guilt from pet owners may be another factor in understating goldfish memory. "I suspect it's got more to do with making us feel good about putting them in a tiny little bowl," Brown said. "It probably says more about us than it does about the goldfish."
Properly cared for goldfish can live 20 years, so owners might want to consider getting their pets large tanks with enrichment objects and companion fish, as well as taking the time to play games with them and teach them tricks, Brown said. After all, your goldfish might remember certain experiences for years to come.

Have you ever walked into a room, and then completely forgotten what you came in for? We often compare this frustrating experience to the life of a goldfish, as though they are always forgetting what they were just doing.
Goldfish (Carassius auratus) that swim inside your fish tank are much smarter than you think. This myth about them being dumb has prevailed, even though scientists have known about their memory skills since 1960. In fact, people generally look down on fish, though some of them may be smarter than chimpanzees (our relatives, evolutionarily speaking).
He placed a red Lego piece on one side of his fish tank and then dropped food next to it. Initially, the goldfish avoided the Lego out of fear, but after some training, it seemed to have gotten used to the foreign object. Eventually, the goldfish started associating the red Lego with food.
He tested this by feeding the goldfish for a week without putting in the Lego piece. If it had a poor memory, then Rory putting the Lego piece back in should have scared the goldfish away, just as it did the first time. However, Rory found that the fish swam towards the Lego piece faster than before, showing that these fish can effectively retain knowledge.
Not only can fish remember how to avoid the bad and seek the good, but they can also develop their own systems for remembering things, similar to how we navigate the streets in the towns where we live.
Several major drugs have been suspected of impairing memory, like Dizocilpine. Some researchers even set out to determine if this was the case and found that Dizocilpine did, in fact, significantly impair the memory of goldfish.
In conclusion, memory is an important aspect of all of our lives. In the case of goldfish memory is a necessary tool for survival when it comes to remembering feeding or even remembering predators in the real ocean. We should all experiment on all of our pets to see how long they are able to remember things.

Kat - It's not clear where this myth originated, but it's often been used for comic effect, particularly by people whose memories aren't the best... What was I saying? There's even been a movie named after the supposed phenomenon - a romantic comedy rather than a fishy feature film.
In fact, most fish - including goldfish - are more than capable of performing pretty good feats of learning and memory, and anyone who has kept pet fish will know that they're not usually swimming about in a permanent state of freaked-out amnesia. And it's not hard to disprove either - the claim has been debunked by many people; from university researchers and TV mythbusters to curious schoolkids.
For example, there's evidence that fish can distinguish colours, shapes, tastes and sounds. They may even recognise their owners, and certainly learn to become habituated to them, as well as other fish in their tank. And these memories last for months, not minutes.
(adsbygoogle = window.adsbygoogle []).push();According to a study by animal psychologists at Plymouth University, goldfish can even tell the time. The researchers trained the fish to nudge a lever to get food, but they fixed it so it only dispensed the goodies for one hour per day. The clever fish adapted quickly, learning to cluster around the lever as lunchtime approached.
Scientists are now trying to unpick the molecular nuts and bolts that underpin a goldfish's mind, by training them to respond to different coloured light cues associated with food. And it's likely that the fundamental processes at the heart of a goldfish's mind are similar to those in ours, despite a few million years of evolutionary separation.
Furthermore, scientists have studied other fishy minds. At the Society for Experimental Biology annual meeting in 2014, a Canadian researcher presented data showing that African cichlids - small fish that are popular in domestic aquariums - can be trained to go to different parts of their tank to receive food. After three days of training, the fish were put into a different aquarium for 12 days. After that, they were popped back into the training arena, and showed a strong preference for seeking out the areas where they'd previously found yummy food.
Of course, it makes little sense for animals like these fish to have virtually no capacity for making memories at all. In the wild they need to be able to remember the locations of safe places to eat free from the threat of predators, so while they're unlikely to win Mastermind any time soon, it's not surprising that they have a reasonable amount of brainpower. And, of course, any fish that can't remember the location of dinner aren't likely to do very well in evolutionary terms.
There's more. Scientists in Israel managed to train sea-dwelling fish to respond to particular sounds played over an underwater loudspeaker, coming towards the source of the sound and return for food. Importantly, they could remember their audio cue months later, flocking back for a feed when the sound was played again months later after living in the wild. There's more to this than a biological curiosity though. Many species of marine fish are farmed in large underwater pens, and this can have knock-on effects on their health and wellbeing. Perhaps a sonic signal, sent out to free-living fish that have previously been trained in captivity could be a good way of enticing them back to be caught,
Finally, perhaps my favourite fishy fact that I've discovered is this: goldfish can tell the difference between different types of music, according to a study from Japanese scientists. In their tests, fish were able to discriminate between the famous Toccata and Fugue in D minor by Johann Sebastian Bach - a piece of neatly precise organ music - and Igor Stravinsky's effusive and orchestral Rite of Spring. Although the main finding was that they're not really fans of loud music at all, which isn't that surprising.
