Yes they do. Horses sleep standing up ahahah.
Yes they are sleeping. My goldfish sleeps too!
Yes, fish like betta will go pale and rest when it's dark. They aren't technically asleep as they can't close their eyes, and may still need to react to some nocturnal predator, but they are generally inactive and "resting" Other fish are more nocturnal and come out to forage or hunt at night more than during the day.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
