One of the things I find rather disheartening about this hobby, is that anyone with money, space, and time can essentially turn into a "skilled" fishkeeper overnight- that one rich twit down the road that everyone seems to know can one day buy himself a massive 800G, stock it with a couple expensive fish, run a state-of-the-art filter and whatever other fancy equipment on it, proclaim to the world of their new setup, and get hailed a hero and expert for their financial decisions.
I'm not sure if I agree with this or not. Certainly, there are folks who feel that by throwing enough money at a problem they can make it go away...but unless they spend the cash required to pay someone to maintain their aquarium, no amount of fancy-shmancy hardware can overcome a complete and utter lack of knowledge regarding how to use it correctly.
It's like having a tank infested with Ich; all you need is a heater and some salt...or even just a heater! Owning an aquatic medicine cabinet with all the latest miracle cures, along with some goodies like a UV sterilizer, a diatomaceous-earth or other ultra-fine filter, maybe an ozonizer (does anybody still use those?) means that you probably have a half-dozen ways to treat the problem quickly and effectively...but if you haven't a clue how any of it works or which bottle of medicine to use...your fish will still die, whether by the ravages of an easily-cured parasitic infestation, or by your own hand as you bumble about with stuff you never bothered to learn how to use.
I think that's why many of these "credit-card aquarists" seem to fade from view shortly after their glamorous shiny new aquarium starts to develop "mysterious" problems; they get discouraged when pulling up their bank balance on their cellphones and then showing the fish how much money they have spent doesn't remove the white spots immediately...
On to the next hobby, something that more easily lets them display the sort of conspicuous consumption that was the original goal.
