This year at the Intel International Science and Engineering Fair, there was a project where somebody took the Mythbusters thing a step farther. Not only did she teach goldfish to run a maze, she taught one to herd smaller untrained goldfish through the maze to the food.
Some fish are pretty dumb, but nothing that actually has a brain has such a short memory as fish are often reputed to have. A lot of things without true brains have a longer memory than 3 seconds.

No worries on it, but as someone who occasionally puts a lot of efforts into a decent post (such as the species guides on frogfish or the article on the true definitions of school and shoal) and has had photographs published in aquatic literature, I prefer to see sources attributed. I understand it was an oversight, but some people are just too lazy to take 5 seconds to copy and paste the link too.
Glad to see you added the source
Maybe Axle has the ability to respond in an adult way to a valid point?
Yea, I've never understood the whole 3 second memory thing. I've never believed it either.
There's many things we can all name that our fish do that they wouldn't be able to if they had such a short memory...
Go to the same exact spot daily for their food.
Recognizing individual people that are their owners and shying away from anyone else. (cichlids especially do this)
When chasing away intruders from their eggs, know to hurry back because they have eggs to protect. (Studies were done with fishermen years ago that when a fish is caught sitting on a nest, when released it immediately goes right back to the same spot to protect them)
That's just a couple that prove they have intelligence and a memory. At least, imo.

My cichlids were very shy around anyone but me. Last summer I got bored, and had a lot of blond highlights put in my hair...I mean a lot, and I was practically blond! I fed the fish that evening, and normally they'd be pushing each other out of the way. When I approached the tank, they all headed for the rocks! I was amazed...
Well, our plants "remember" how long the photoperiod in the tank is. Anyone who has ever grown Hygrophila polysperma will have seen the way they start folding their leaves about an hour before the lights go out. The "primitive" worm Caenorhabditis elegans, simpler in structure than the Planaria we see in our tanks, can learn complex patterns of behavior*. Does this constitute "memory" as we know it? I think this is a question of semantics. Imagine a weathercock. It'll turn whichever way the wind blows. If it becomes calm, the weathercock will keep pointing in the direction where the wind used to blow. In electronics, this is pretty much the definition of what memory means. Yet nobody thinks that a piece of metal on the roof actually remembers anything.
* Just to be clear, I don't mean C. elegans can learn to navigate labyrinths or run obstacle courses. They don't have a brain, so I was speaking in relative terms. They will learn to associate various combinations of light and chemicals with food, for example, and this learned behavior will persist throughout their lives.
