Hmmm i feel it really depend on what is the interest. Most of the local reefers are more into coral, so it LFS bring in unique or rare coral, a lot will be going after it if budget allow. Fishes at most is only to make the tank more lively so one will rather go for common, nice and easier fish then to go for unique/rare fishes which might be difficult to keep or some that might pose a threat to the coral. =)
