AquaExhibits is fine if you get something from the fresh shipped (kind of like Pet World). If its in their system for a week, then it gets sick, but the quality from their distributor is fine.
Also, be aware that their worker's vary in knowledge, and the fish systems are actually at 1.010-1.012. So acclimating the fish should be done very slowly. I did so over the course of a few hours... a bunch of yellow tangs no less, and they have been champs.
I go there, knowing that alot of stuff is dying, but every once and a while they get in some very exotic, super-cool stuff... octopus (large and small), mantis shrimp (full size ones no less), weird crabs, etc. Im hoping they get more of those 1.5" long $50 anglers this year again... they were the coolest, and now I have a tank that I could keep one in.
