Some people say that a goldfish has a memory span of 5 seconds. This is NOT TRUE! Goldfish are incredibly intelligent and have a memory span of three months and longer. Goldfish have been known to respond to light, sound and color, they can even recognise different people.

When a scientist wants to test the memory of a goldfish they usually pair some form of light, color, or sound signal with food and using positive reinforcement to create a desired bahavior (goldfish can do tricks like slalom and play fetch). When the behavior is learned the scientist quits making the fish do the trick. Then, after a certain amount of time (say two weeks or a few months) the scientist will use the stimulus and see if the fish remembers to do the trick in order to get the food. That is how the memory is tested.

There have been a few studies on it, goldfish actually have a memory of about 3months. There have been a few studies on it, goldfish actually have a memory of about 3months.


Scientists are not really sure how it happens, but the part of the brain responsible for memory is in the limbic system, a part known as the hippocampus.


I believe not. Unless scientists do some weird cloning thing, that's not possible. But I hope not. That would be really weird.


Yes, you can train goldfish. Goldfish are extremely intelligent animals and are able to learn a wide range of tricks! If you are thinking about training your goldfish you might want to look on you-tube and try to find a tutorial for training goldfish. It really annoys me that people say goldfish are unable to be trained because they have a memory of 5 minutes, when in actual fact, many goldfish have been trained and they have a memory of up to a week. so, if you keep repeating the trick every few days or so, then your goldfish will learn the trick. PS. i have two goldfish and they are both trained, they can: eat from my hand, keep a little plastic ball from sinking by bouncing it up with their heads, one of them can blink, and, they both beg for food. Good look training your goldfish, i hope it is a success!


A fat goldfish is unhealthy, and the reason for the fattness of some goldfish is because of over-feeding. Though a goldfish owner may think that their goldfish are really hungry because they eat everything the owner puts in, a goldfish will really eat anything as mcuh as it can like it is really hungry. The biggest mistake goldfish owners do is overfeeding their poor goldfish. I always give my goldfish one day of fasting per week, but a fasting day isn't necesarry when you feed it the right, small amount.


yes you can give your goldfish bread but then your goldfish will get really fat if u feed it too much or sometimes all goldfish won't eat it


OK really!! it's not a reptile it's a fish why do you think they call it a goldFISH


If a goldfish attempts to eat something that is too big to fit down its throat, it will spit it out. Really the goldfish is 'Coughing'!


get a goldfish and test it out i have a gold fish it dosent really make a difference


Goldfish is a type of carp and when they get really bigthey start to turn in to carp kinda!


A goldfish will probably die in soapy water, unless you change the water really really fast completely with nice, clean, no-chlorine drinkable water. All the harmful stuff in it will kill the goldfish!


Oscars eat goldfish. Therefore, does it really matter if Oscars are faster?


Well, i really dnt know



There is really no commensalism that takes place between goldfish and other creatures. Occasionally, goldfish will clean their homes by eating leftover food and waste products.

I really would not put the tadpoles in with the goldfish...the goldfish will most likely eat them all. It depends on the goldfish size, but eventually they will try to eat the tadpoles whether they suceed or not. :/


It is safe to touch goldfish, but they don't really enjoy being petted. Fish are not as affectionate as mammals are.


Yes i have one goldfish and one angelfish and they do not fight people say they do but they really don't.


you should'nt put parrotfish with goldfish. Parrot fish are known to be be quite mean. It will eat or kill the goldfish if it is smaller than he is. So unless you have a really big goldfish, I suggest not putting it in with the parrotfish.


If they are not friendly goldfish species than they will but in general they don't. If they do than you probably don't feed them enough but that is really unlikely.yes they do. Its all a matter of size.


a goldfish plant is really just called a weed. And apparently 'Weed' in french is "mauvaise herbe"


i would say that they are more of a shiny orange than a gold. But some goldfish can be more yellow/gold.


NO,they will not eat newt eggs unless there really hungry the will stay with goldfish flakes and other stuff


No, if you really look at them, most of them are really orange, its hard to get a real gold fish. == ==
