what's unrealistic is comparing human behavior with fish.
#1 Reef's don't typically have strong currents, Reef's are in shallow water.
#2 What an animal does in the 'real world' to survive is MUCH different then what a domestic 'pet' does. Even if your fish came from the ocean, it's now in a fish tank and has adapted to a much different life.
#3 Swiming into a power head in open water is MUCH different then swiming into a closed tube with water being forced out of it.
#4 Are you saying fish a dumb? Because I've seen a tang that eats out of ones hand and actually allows you to pet it. Not dumb by any means.

Also how many fish under 1" in size do you know that swim 'upstream"? None! Fish that small arn't big/strong enough to fight a current.
