Fragbox in Toronto sells captive bred fish so imo no need for QT. Ive bought fish from them many times always tiny little babies when I get them but much easier to care for than wild caught fish and much less risk of anything coming in on the fish.
I'd contact Chris at Ethical Aquatics. Great guy, and he shipped all my stuff before the couriers became horrible and completely unreliable. It should be much easier to ship across the country than it is to northern Alberta, though.
