Cory keeps a tight, well-run ship at the Aquarium Co-op. Every tank has its own individual filtration, and is also on an automatic water changer, so that the fish are in top-notch condition. He is also an active member in the Greater Seattle Aquarium Society (http://www.gsas.org/), a really great organization of fish keepers in the Seattle area that my grandfather likes to frequent. They have a great website to peruse in addition to the meetings/auctions.
Below is Hank the Mbu Puffer, Cory's son and and amaaaazing presence in the shop!
