Well Now that I've had them roughly a month here's an update. I had a group of 12 cardinal tetras and 12 runny nose tetras come out of quarantine yesterday and are in the tank swimming around. The discus did manage to eat one upon acclimation but the rest are semi loosely school in the top portion of the tank. The discus are seem less football shaped on 50% daily water changes and are being feed a variety of frozen foods.
Sea level is easily one of the best lfs's I've worked with to the point of offering to exchange an undrilled tank for a drilled tank even though I didn't purchase it there. He also gave a me free food and a discount for just buying the fish.
Cool man. I can't see my Discus chasing down any fish and eating it. They seem to have enough trouble catching floating flakes :/
