what is the memory span of tropical fish?

Answer 1

According to scientist most tropical fish have a three month memory. It is a myth that they have a one second memory

Answer 2

In tropical fish studies - in Goldfish - experiments show that once they're taught to perform a certain task in response to a certain stimulus, goldfish will remember the task for several days.

Yet off the topic of Tropical fishes - another example of fish memory is the way Salmon use their sense of smell, (or what's known as olfactory imprinting), to return to the same stream they were born in during mating season. Some species, like the arctic char, can remember the smell of their siblings for days, and others can remember and recognize specific fish who are aggressive opponents.

Also - all fish eventually encounter new types of prey, become efficient at feeding on it, and then remember their new skills up to a month later when they encounter this prey again.

So basically fish learn and remember where their nest is, what the boundaries of their territory are, and where their mates, food, rivals and predators hang out, and even possibly what they look like.

So - they might not look like it, but fish can have pretty good memories.

Answer 3

Goldfish and betta have greater desirable innovations than 3-seconds. A betta (or the different fish) could be 'taught' to affiliate a human simply by fact the provider of its nutrition. This demands rudimentary memory. it extremely is antagonistic to a wild betta which might instinctively flee a human simply by shortcoming of nutrition affiliation. do no longer feed it for 3 days and then mindset its tank. it is going to 'remember' which you're that's nutrition provider and assume a feeding consultation even however 72hrs handed. in simple terms inspect its habit. some 'sensible' fish like particular cichlids and puffers (between others) can know their owners/feeders from strangers. That demands keeping memory of particular human beings.

Answer 4

T.Vs Mythbusters trained goldfish to swim through a maze to reach food daily, proving a longer memory, although I dont know exact length.

Answer 5

From what I've heard, fish don't have a very long memory span at all. I can't swear it to be true, but I have heard it several times.. no memory to speak of . Good Luck ! :)

Answer 6

It really depend on what you mean by memory span. For most things it's about 3-7 seconds, but they can be conditioned by repeated stimuli. I've trained my fish to come to one corner of the tank when it's feeding time. (It makes neting them easy.)

Answer 7

dont know abt tropical fish...but golden fish has 8 seconds memory.

Answer 8

They say seconds, but I find that hard to believe as some seem to know what sort of movement is going on around them.

Answer 9

It is seven seconds - exactly the same as goldfish.

Answer 10

I'm a clownfish , what was the question again.
