Sadly there is no such store within 150 miles of myself. The one 'good' store does not qt fishes; will rarely take special orders and almost never carry more interesting stock. The lack of qt'ing really bothers me as i've been bit a few times. I contrast this to places like wetspot and aquarium-cop which have a policy of qt'ing new fishes. To add insult to injury the local shop charges a premium price on the live stock. It is almost certain that I will buy nearly all of my future fishes via mail-order - i just have to make sure there is enough fishes involved to offset the high cost of shipping.
I also buy locally. No online. My LFS actually special ordered my Filament Barbs. No shipping cost & they acclimate the new arrivals to area water.
I think most quality fish stores will special order.
