Betta shows? And maybe your local fish/pet store. Surprisingly even chains seem to be stepping up their game lately, saw a gorgeous copper dumbo delta male at Petco. If you go to Aquabid be careful to note the country of origin.
@Jcal: im admin for a betta sales page (partial reason why i dropped off the face of TF). most listings are imports (there are transhippers, kinda like importing neps from wistuba), though we do have a few individuals who have already imported stateside, and ready to sell. Kasey Clark is who'd you'd like to contact. You might even recognize Javier Garcia if youre deeply vested in Sarrs. Small world, right? Any who the link: Entrar no Facebook | Facebook
