Basically, the thing that needs to be kept in mind with these shows is that they are, um, well, reality TV, and these people are tank *manufacturers* first. In fact, it looks like making tanks and doing TV are jobs 1 and 2, and the other things are generally handled by affiliates while using familiar faces. We, being that we are people acutely *interested* in the facets of aquaria that don't make for good TV, want to see behaviors that we just can't. Sadly, we comprise a significantly small minority of the population. Just looking at my workplace, and considering the number of people who have bettas in 1 gallon or less bowls, unheated and unfiltered, as being full blown and hardcore aquarists, maybe as many as 8% of the people that work here would fall in that category. Since we all know that many people who keep bettas don't have good success rates because they're, well, just not that interested in doing things the "right" way, we know the actual figures are lower. Since one of the main jobs is to make a TV show that attracts viewers (and therefore dollars) and the other main job is to sell custom/stock tanks, they don't have much choice but to make shows that have potentially controversial tank/stock combinations, because it that way makes it sexy for the sheeple that drive ratings, and doing it slow and educating clients that are disinterested in proper care does not make good TV.
