That's in the thread (in one of my posts - two examples). But the thread isn't 7 pages of belly aching. At least the first couple of pages has these three important points:
1) Many coral sellers, though not all, whether individuals on fleabay or small start-ups, artificially enhance the photos of the corals. These corals will never look like the pictures, either in the dealer's tanks or the customer's.
2) Buying named corals often means paying greatly inflated prices for small frags vs. buying unnamed colonies for much less.
3) Typically, hooking in to a local club and/or finding a good LFS if available will allow someone to stock a tank for much less, and it's truly WSIWYG, since it's in person.
