When I was about 7 or 8 my mother took me and my brother to a card shop. On the counter was a fish tank full of water with a bubling water filter inside.
It was suspiciously absent of fish. I am not sure, but I think I asked my mom why there were no fish.
In front of the cashier she told me there were fish in the tank, they were just invisible and that they would appear when the moonlight shined on the tank at midnight. The cashier seemed to happily confirm this fact.
I stared at the tank to see if I could see any movement, but it was difficult with the bubles bubbling from the filter. My imagination would conjure up visions of moon light streaking in from front of the store while it was dark and the store was empty and the fish suddenly appearing.
I thought this true for years until I was a teenager. My mom liked to tell me things like this.
