Getting a little aggressive guys...
@Mucho, as a newbie I wasn't around 10-15 years ago to see the prices. But those sale posts of yours, they don't show any pictures so can't say I'd have bought them, I tend to like seeing what I'm about to buy.
My one question because quite honestly I can't wrap my head around this. You legitimately believe that there is 0 cause for rising prices outside of these sellers that you say jacked the prices up?
As with anything the cost of keeping a tank, raising corals, etc., has gone up. What has changed is that a perception of rarity has been created and thus caused much higher prices for fragged corals. Prices that folks, who often don't know any better, are willing to pay. It's sort of a self fulfilling prophecy in that the individual, who now owns a 'rare' frag wants to recoup some of the high cost so he frags it, gives it a new name like Ultimate Thunderdome, and passes it off as 'rare' to someone else.
I'll give you a similar example, one that did affect me greatly, and that's the .22 ammo shortage. Now this shortage never really existed but the myth was perpetuated on many message boards I frequent. As a result, hoarding of .22 ammo became the norm to the point that many people had 15,000+ rounds stashed. They'd go into a store that happened to have some .22 on the shelf and buy everything in sight. At some point these people decided they had enough ammo for themselves but they continued to buy everything up in sight and then sell the ammo on sites like Gunbroker at huge markups. They'd then take the profits, buy more ammo, and perpetuate the cycle. So what happened?
Shooters like myself had two options, pay the ridiculous prices for .22 ammo (think 4-5 times the original price), or stop shooting altogether. I chose the latter and didn't go shooting for 14 months. Once I was able to start buying ammo at normal prices if I ran into a shooter who didn't have any, and I had extra, I sold it to them for what I paid for it. If they needed it for a kid, I'd give then 200 rounds at no charge. I could have marked the cost to gouger prices but why?
Now the larger question is what has been the long term affect of the artificial shortage? Less new shooters, why buy a gun if you can't get ammo for it, and additional shooters dropping out for the same reason and taking up new hobbies. As a result the number of shooters at the gun club I belong to has dropped.
Do you see the correlation to saltwater tanks? Lets say a newb is looking to start a new tank. It's already crazy expensive because they'll probably buy new equipment because they don't know any better. Now they look at the cost of corals because really most people don't want a FOWLR tank, and the sticker shock hits again. That person may decide it's just too darn expensive a hobby to get into. The higher the cost to play, the smaller the market is who can afford to play.
I'll put it another way. I head over to the LFS and I see some really nice coral frags. Now I know they're under LED lights, lights I don't have (I have T5's), and I look at the prices which to me are way too high for how small the frag is so I pass. I pass because I know the prices are too high and the LFS has lost a sale. I also frequent the message boards for several local clubs and they're not too far off when is comes to pricing for frags. Everything is 'rare' with the price that goes with it. Again, I chose not to purchase because I know the price is too high. The end result is that I have very few corals in my tank. Am I happy with it, nope, but I chose not to pay to play. I started tanks back when you pretty much gave away frags to friends or if you sold them is was for $5 / $10 a frag, beer money as we called it. To this day I would happily give away a frag of anything I had in my tank to a friend or still charge $5 / $10 max. I see it as growing the hobby rather than a way to make money. Maybe it's an age thing as I'm 56 but it's how I choose to live my life and hopefully grow the hobby.
At a time when everyone wants the market to grow, more growth in theory leads to lower prices for equipment, tanks, fish, salt, etc., the high cost of setting up a tank is shrinking the market. The demise of the LFS is not entirely due to the online stores, part of it is the cost of entry to the hobby and the long term cost of creating the tank you always wanted.
Now I'm sure some of you, maybe most of you, don't see anything wrong with the current pricing structure for corals and that's your choice and you're entitled to your opinion. Would you feel the same way if the cost of lighting tripled, quadrupled, because new there were 'rare' LED fixtures? People buy them, manufactures of less expensive LED's see that people are willing to pay stupid prices, so they raise the prices for their 'non-rare' LED's.
This is what the whole fragging, crazy name, thing has done to coral prices. Basic corals such as Frogspawn, Leather corals, Hammer corals, all of them have seen significant price increases because the LFS, and online retailers, have seen how much people are willing to pay for so little.
