The people on that show are awful. They put the spectacle of their ridiculous tanks above the well-being of the fish. I know there are proponents of the concept of an instant cycle, and while I’m not sure I’m convinced of (converting ammonia is only part of the cycling process, IMO), putting 15 fish in an hours old aquarium with only some bottled bacteria and no live rock is just irresponsible and unethical, and they do this for every aquarium they set up (I know people do this for trade shows, but they only leave it up for a couple days and do massive water changes if need be). I also think the show gives people a really unrealistic view of the hobby.
