Your Trusted Aquarium Experts

It was in August of 1969 that Aquatics Unlimited first opened its doors on the corner of 95th Street and Greenfield Avenue in West Allis. Most of our dry goods fit on a single 8-foot shelf, our “cash register” was a cigar box, and all-glass aquariums were but a glimmer in somebody’s eye. On busy weekends, we doubled our staff to two. The past five decades have seen four different locations, a lot of water changes, and plenty of new faces, but our aim is still the same – to provide “The Best in Tropical Fish” and aquarium equipment. We’d like to take this opportunity to express our thanks to so many faithful customers who have helped us towards that goal.
