Oh well. I guess I necro-ed this thread. Best place to purchase/order fish in Tulsa was
PetSmiths (actually in Bixby)...just closed within the last several months. Southern Agriculture on 71st and Sheridan is a pretty good place for fish but supplies will be significantly higher price than PetCo or PetSmart.
After seeing Fintique in San Antonio a few years ago, I see just how deprived our area really is...but I guess it's all supply/demand.
