The Milwaukee Aquarium Society is Milwaukee’s oldest fish hobbyist organization, helping to promote the hobby in Milwaukee since 1955. Building on our rich heritage, we have grown to 50 members, representing a combination of individuals and family memberships.

The interests and experience levels of our members vary from people who are just starting out in the hobby to experts who have received national recognition for their accomplishments. We are proud of the many members who boast 30 years or more of aquatic hobby experience.

Whether you’re looking for a mentor to learn from or just a great group of people to hang out with, you can find a place with MAS. Our members also receive discounts at many of our local fish stores, as well as the chance to participate in our annual MAS picnic and the MAS Christmas party.
