The Minnesota Aquarium Society (MAS, pronounced M--A--S) is a collection of local aquarists with the purpose of learning, sharing information, and motivating each other.   By raising the bar of our expectations and meeting monthly, members go deeper in the hobby, try new aspects that they never would have on their own (like building a "fishroom"), and stay in the hobby much longer.  There is something about associating with others who share our passion.

MAS was founded in 1931 and incorporated as a nonprofit in 1956 with the expressed goal of studying and keeping aquatic life and fostering a community of aquarists.

The information below has been revised for how we conduct our programs during the Covid-19 pandemic.

MAS programs:

Monthly Meetings  are now online and are held on the first Thursday of every month.  They are open to the public - visit our home page to find the link for registering and attending.  The focus of each event is a topic-driven program, featuring a nationally recognized expert.  These meetings are conducted with Zoom and maintain an interactive meeting format, and only the presentation portion is in the "webinar" format.  After the initial presentaiton, attendees may stay in the main room to ask the speaker questions, or they by select one of our themed breakout rooms, each moderated for small group introductions and discussions. See this page for the full details about the online meeting.

Quarterly Online Auctions allow local aquarists to sell and buy fish, plants, tanks, and gear.  Expect many fish that are locally bred and plants locally grown -- and often of hard-to-find species.  Our online format allows for social distancing as well as conveninence.  Participants post fish and plants, buyers bid on them.  Bidding ends on a Wednesday, buyers pay online, and Saturday we host the distribution at a single location, practings social distancing as sellers drop off their items late morning and buyers pick up their items early afternoon.  On this page we maintain the current rules and details.

Annual Weekend Event.  Each year, typically in the Spring, MAS sponsors a free city-wide event that includes a display of at least 100 aquaria along with other activities and speakers.  In the past these were held in public places like Como Park, Rosdale Mall, etc, and now at Augsburg's Hagfors Center.  At the Aquarium Expo, members display their best and reach out to the public with presentations and the offer to help them become more successful.  ...Unfortunately, we are unable to hold an in-person annual event until the pandemic clears.

Breeders Award Program (BAP), Horticulturists Award Program (HAP).  For over thirty years MAS has been running these programs to track the breeding and growing successes of its members and to publically recognize accomplishments with awards at the Membership Meetings.  We have found that these organized programs have encouraged new people to try breeding fish and growing plants and to advance in these skills.  Because we are not able to meet in person, we are holding the BAP/HAP submissions and auctions every three months via an online auction.

Special Events.  From time-to-time MAS will organize additional events.  In the past these have included fish collecting trips in the local streams (MAS obtains permits), tours of local members fishrooms, and bonus talks by out-of-town speakers, tyically held a member's home and fishroom.  

We, the members of the Aquarium Society, invite you to join us.  Hang around a little and we'll motivate you to take your hobby further and to become a better aquarist.
