Several months ago this story was being talked about and I personally have seen documented evidence that the theory Goldfish only have a three second memory was a mere fishtale....I represent to you the updated Story of "Nemo"....
We have in addition to our other myriad of pets, a goldfish. Not one of those pricey pet store ones, just your average run of the mill throw a ball into a glass jar at a fair type goldfish. He or she (not sure which...lol) has managed to survive almost 3 years and that is with several attempts on his life where his little plastic fish tank was knocked over. About nine months ago I decided to get "Nemo" a new tank, mainly to stop the cats from trying to knock over his bowl. I chose an inexpensive hexagon shaped one that had a filter, a step up from his former filterless habitat, mainly in the hope that the cats couldn't perch on top of this tank given the shape. (and it was cheap....after all...it is for one fish)
My fear of course was after being moved into upscale goldfish housing he would die. Nemo however has grown and seems to be much happier, infact he's developed quite a personality. A personality in a fish? Yes, I am not crazy others have witnessed his behavior. When seeing a person approach his bowl he wiggles himself in an extreme fashion, we know this as to mean "FEED ME!" When the cats approach his tank, he swims around the whole exterior of the tank, which makes them chase him, which causes me to yell at the cats, and Nemo goes to the top and blows bubbles, as to say "HAHA CATS!". If a cat puts his paws up to where Nemo is he retreats, if a human puts his finger up to side of the aquarium Nemo goes to it.
A human nearing his tank, then creates the "FEED ME!" frenzy dance. He seems to be able to tell when it is a new person near his tank. If I feed him he stops, yet if someone else approaches the tank even though I've just fed him, he preforms the "FEED ME!" frenzy dance.
Did you feed the fish? Is a regular question around here, and when you answer YES!, the response is usually "Well HE said you didn't".
