Serving the Greater Milwaukee Area since 1969!

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 few 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.

Aquatics Unimited IS ""

In the 1990's scramble for .com identities, Aquatics Unlimited was looking for a name that was (1) still available, (2) easy to remember and (3) easy for customers to type and spell correctly. Since our logo and advertising had contained "The Best in Tropical Fish" since 1969, was a natural choice. We are not affiliated with any other pet or aquarium business, in either the real or virtual world.
