Interesting and thought-provoking thread
I must respectfully disagree with Xcreamist regarding the price of saltwater organisms. Considering that many of them come from remote parts of the world, the mortality, the freight charges, the middlemen and women, I can certainly see why a Yellow Tang costs $20-35 by the time it reaches you and I. I am in the business, so I might have a bit different perspective than one who has not had much "behind the scenes" experience.
MOST freshwater fish are now propagated at fish farms all over the world, and most of the popular species are readily available cheaply, and in many cases, locally. Less expense, less mortality, less cost, cheaper retail price.
As to why people quit the hobby....80% quit within the first 6 months. Why? ALGAE! Algae is the #1 detractor. Figures...a maturing tank goes through the most algae blooms in the first 6-12 months...
I do agree with the posters who observed that it's the MTV generation mentality where every fad is a flash in the pan and they move on to something else. As mentioned, check any animal shelter...this attitude is not limited to fish. It boggles the mind that people will pay hundreds and thousands of dollars for a pedigree dog, fancy cat, horse,exotic birds, fish....heck some people even have CHILDREN and then cast them aside.
My children are in elementary school. They don't play video games, they JUST got a computer to play with (no Internet, just some educational software), they don't watch much TV, except stuff like Animal Planet and Discovery Channel..they devour books and they spend as many hours looking at the fish and corals as my husband and I do. They fully understand the work involved, and very soon I expect to set up a tank for my older child, as she seems to share our passion for the hobby. Our son, too will probably want his own tank in a couple of years. They already share the responsibilities of taking care of the cats and dog, so they are aware of the care that animals require. These are the hobbyists (and hopefully responsible adults) of the future.
Education is the key. I've been guilty of "scaring" away somebody or two that from conversing with them, I've concluded they don't have the intelligence or the inclination to do what it takes. Sorry if that sounds insensitive or not politically correct but when an explanation that freshwater fish live in ponds, lakes and rivers, and saltwater fish live in the oceans doesn't distinguish it for someone, I have visions of them putting a Naso tang in with their neon tetras.... If somebody doesn't grasp fairly easily, that these won't live in fresh water..well, they have a LOT of work to do before I would consider them qualified to part with any of the specimens *I* was selling. I've serviced a tank recently, belonging to a wealthy family, who also have 5 dogs and 2 horses. The fish were sick with HLLE...they don't care, they don't understand...their filtration was inadequate and their nitrates were over 160 (my test kit only reads to 160!)...I convinced them to upgrade their system, and took their fish in for treatment, but two weeks later they have YET to confirm the appointment to perform the upgrades....of course 3 of their dogs live outside and are never paid attention to, and the other 2 are always crated indoors when I've been there on 3 occasions. The kids are left in front of the big screen TV while mom is upstairs...each of the 3 times I've been there...Respectfully, these are not hobbyists, they just want status symbols.
I think there are enough hard-core hobbyists such as ourselves to help make a difference educating those with enough interest, but the bottom line is that only a small percentage of those people entering the hobby have the inclination to do things properly.
Ethically, I have no problem scaring away people who aren't committed. If they ARE committed, nothing *I* or anyone else can say will scare them off. Discouraging someone who won't do it "right" will save at least a dozen or so lives of the creatures who will be sacrificed to their ignorance.
