Expert Advice – We firmly believe that well-informed aquarists make the best customers. If you have a question as a beginner or an expert, just ask. We’ll try to answer from our years of experience – or help you look it up. The only ‘dumb’ question is the one not asked. Water Testing – We’ll test your aquarium water for the ammonia, nitrite, nitrate, pH, hardness and specific gravity at no charge. We also test copper and phosphate for a small service charge. Just bring in a cup or so of aquarium water (water only, no fish) in a clean glass jar or a new plastic bag. Trade-Ins – We accept trade-ins on healthy fish and major aquarium components (tanks, tops, lights and stands). Items must be in good condition (no missing parts) and reasonably clean. On common tanks, tops, lights and stands, we pay up to 10% of the new value in credit for other merchandise. We also accept most types of fish in trade for other merchandise at up to 1/4 the retail price. Bread & butter fish may be brought in small quantities at any time. For large, expensive or saltwater species, please call ahead. Seasonal pricing may apply on some items, including pond fish, and we may pay little or nothing on fish (for example small convict cichlids and some large cichlids) where the supply currently greatly outweighs the demand or the tank space or care required outweighs the value of the fish. Please call ahead with any questions.

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, a nd 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.
