Just wanted to give a recommendation for Discus Madness. I went to their facility this past Saturday in NJ and was really impressed. Very clean, well managed operation, with 100's of beautiful discus fish to choose from. The owner was extremely helpful but also let us take our time looking at the fish and making our choices.
I ended up picking up 10 juvenile fish; they're a great addition to my 165 gallon tank. They also had a number of larger discus, as well as other discus tankmates and supplies. I ended buying some of his beefheart mix as well, which the fish seem to love. I'm very happy I made the trip out there, I've never seen so many great fish in once place before. it reinforced my love of the hobby.
