Goldfish remember better in cold water than warm water.

and.....how do you know that???

lol what COULD they remember exactly? it's a goldfish, come on! it has a brain the size of a fingernail on a baby.
Goldfish 1: Dang forgot where I put my rock at.
Goldfish 2: Uhhh duh.... Go swim in cold water.
Goldfish 1: *swims to coldness* OH I remember, it's right here!

COOLLLLLLL!!!!

its hard to believe that this is true because the previous facts are filled with comments that show that the fact is not true...

Oh well, we can make cool skits about it like
Fish 1: Hi Nemo!
Fish 2: Hold on, I have to go eat...
[later]
Fish 2: Okay I'm back Dory.
Fish 1: Who are you?

YEA RIIIGGHHTTTTTTTTTT. liarrr

Goldfish are smarter then you think. They have been tought tricks.
You have to remember to judge an animals intelligence by the size of the brain compared to the rest of in not just the size of the brain.
