This hobby is more diverse and alive than ever. Things move on. A lot of brick and mortar stores have become online retailers. The fact there are these $800 corals actually indicates there's now a much wider range of customers and their needs have to be met, which means that this hobby is growing and developing new tastes. Whether you like it or think it's just purely stupid, keep it to yourself. A coral is of no worth if the market despises of it. A frag can be very expensive if there's enough demand and appreciation for the price. I've seen a person recently calling a vendor here "freaking crazy" for selling a homewrecker frag for $600. The thing is, if you don't like the price you don't have to buy it - you don't even have to look at it. Calling it "stupid" and "crazy" is rather rude and insipid. There are plenty of nice corals with very affordable price tags on them.
