Total bunk in my opinion, sorry. My fish are particularly well fed anyhow, but more to the point, it's more a function of their behaviour. If startled, they do a really high energy burst / quick dash to escape predators and whatnot. In the ocean this would just take them ... somewhere else on the reef a few feet away. In our tanks, there's nowhere else to go but out of the tank.
