Franco's Aquariums had some nice ones recently, and I believe that Tanks Alot did as well.....Riverfront had some new rams in a few days ago, but I cannot remember if they were German blues or not. Also check out Gold Aquarium....they get in some nice ones fairly regularly, and usually have the best prices in the city, but you have to be quick, as they sell out fast.
