I saw a small fish bowl and thought to myself “how could a fish stand that little space?”
That got me wondering about the brain of a goldfish (or any aquarium fish of your choice). Do they have the capacity to know they are trapped in a small, never changing space, or are their brains incapable of knowing the difference between living in a river, lake, or whatever compared to that little cube of water?
Do they have a memory, or do they swim around a circle and say “Hey! There’s another new treasure chest! And where did that fake mountain come from?” Or do they know they are trapped and kill themselves to get flushed down the toilet?
(actually, this is a serious question.)
