Oh you people in the US, with your choices and options...here in Canada we only have one transhipper, Hung Pham. Thankfully he seems pretty good. I've used him once so far and he responded to all my emails immediately, fish were packaged perfectly, and Thank God he sent them fed ex, cuz ive heard so many horror stories about Canada post and fish.
Sellers I've received fish from are Psuit, taebetta, sirinutfarm, patsayawan, 3Dbetta, ttbetta, majcha, and Bettaakapes. All were easy to deal with and very polite, and all my fish arrived healthy and looked just like their picture. Really gorgeous fish. I have another batch coming soon, hopefully that goes just as well *fingers crossed*
