I'm sorry but it's really true. I have seen a large number of people that had their tangs in too small of a tank and then died prematurely. But you don't have to believe me, go to Aquarium Fish: Tropical Freshwater Fish and Saltwater Fish for Home Aquariums
and check the recommended tank sizes for different fish. That site is quite accurate with their suggestions. Plus there are many many many discussions on tank size for tangs.
I would also like to point out that fish stores follow absolutely no stocking guidelines. They generally need to keep enough stock on hand to satisfy demand which means keeping a lot of fish in too tight of a space. However these tanks receive absolutely insane amounts of care. One of my favorite LFS
in town does a 20% water change daily on all of his tanks which I would assume number around 40. It's also nearly impossible to keep large fish in a tank size that they are recommended for. There just isn't enough space to do it. You also have to look at the temporary nature of the tanks for these fish, they will usually spend a couple weeks in a tank on average, or maybe up to a month or two for the more expensive ones.
