do fish really have a few second memory and to those who say yes how do u know?

Answer 1

I cant see it because when two fish pair off when one dies the other fish dives in and out of the plants and decor for a day or two it seems to be looking for the partner
Also when my Kriben`s kept laying eggs i had so many Kriben fry i couldn't give them away, so when they kept laying more eggs i was destroying them as soon as i saw them.
The pair of Kribens would then get really frustrated looking for the eggs so if they had a very short memory they would forget almost straight away

Answer 2

A lot of fish have long term memory. Most people claim cichlids are the most intelligent though I'm in a cichlid club so my suroundings and their bias may be influencing this answer.

I've trained some of my fish to do tricks, certain fish recognize me and show other levels of intelligence. One Discus I had knew me and would do tricks for me. When I entered the room it would rise to the top front of the aquarium and on a 45 degree angle shake back and forth. The fish wouldn't do this for anyone else though always did this for me. It knew I was the one that fed him. I could pet him, hand feed him (I used to individually hand feed a lot of my fish and this is a great first step. Sadly I have too many fish to do this with all of them now.), etc. I used to show this fish and it learned to lay down in my hand if I put my hand in the water on a slight angle. This would allow me to take him out of the water and bring bring him to a show or another aquarium, whatever. I don't like food in the aquarium that goes uneaten and spoils so when I feed the fish I shine a small flashlight in their eyes. After doing this for a couple of weeks if they miss some food and it goes to the bottom I can shine the flashlight where the uneaten food fell and the fish have learned to associate the light with food so they'll go to that location and eat the food.

There are a lot of intelligent fish though the most intelligent fish I ever had was a Discus. Oscars are very intelligent and trainable as well. A friend has a Giraffee catfish that acted more like a dog than a fish. You could put things in the tank it would play with. Floating balls, etc. It knew the whole family and would act in a similar manner to my Discus. I think the Red Devil of Midas Cichlids are trainable though I don't personally know any of these that have been trained. I'm sure there are a lot of other fish that are trainable as well.

Answer 3

No, they have a normal memory length. You can prove this because fish are trainable. You can teach them a trick and they can do it again days later. The Mythbusters did this on their show.

Answer 4

My fish remember every day where they get fed. I walk up to the pond and they go straight to the corner where I feed them.

I don't know where these odd people get their ideas from. Haven't they got anything better to do than waste money on research into fish memory?

Answer 5

yea i read it on the internet, on one of those 100 random facts, it also said coke is green before the food dye is put in it[nasty!] oh but about the fish, yea it was either they have 3 second memory span or 15 sec...i can't remember.

Answer 6

No, because my fish know where and when they will be fed. They remember from previous times.

Answer 7

Yes, I saw the mythbusters show too. First answer was correct.

Answer 8

Well I read in a fish book they do, how they know I have no idea lol :)

Answer 9

they done a experiment with the fish and they kept forggeing at the two secounds each time. i think it was on the program mithbusters

Answer 10

i saw it on mythbusters too
