Aquarium Adventure is an off-shoot of the PetLand line of stores but much more upscale. There is a A.A. store in the northwest suburb of Hoffman Estates near O'Hare, there is also slightly smaller location west-southwest in Bollingbrook. One note, fish prices are higher at their stores, especially now with the local swap meets shut down and no competition.I hit up aquarium adventure. Not sure if its a chain or not. New to me. It was the best one out of the 5 or so I hit. Nice plant selection.
