Its amazing what kind of money you can make with a little creative photography, photoshop and a lack of conscience. No way those neon blue zoos will look that way under normal lighting.
Ultimately, I believe legit sellers deserve a premium. Supply and demand ultimately catches up as the corals propagate and/or fads wane and the price comes down. Consequently, those in the designer coral business must constant hunt for the newest and greatest and ultimately hope they don't die when they do find it. Is it clever marketing, you bet. However, I think ultimately its a shot in the arm for captive propagation and conservation.
