Minnesota Aquarium Society

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.
