From beginner to advanced hobbyists, store owners and breeders, there are over 250 current members, making it one of the largest aquarium societies in the country. Everyone is welcome to attend a meeting to find out what it is like. General membership meetings are held on the first Thursday of every month at St. Christopher's Episcopal Church in Roseville.
Most meetings focus on a presentation by a speaker.
Many speakers are our own club members, but several times a year we bring in nationally recognized experts. MAS tries to cater to all aspects of fish-keeping so our speakers cover the full range of topics from aquariums to ponds, freshwater to brackish to marine, tropical fish to natives, DIY projects, spawning fish, collecting wild fish, setting up a tank, disease control, plants, live fish foods, aquascaping, fish shows, and everything in between. Also members may browse or borrow from the MAS library. However, the biggest reason to attend a meeting is for the opportunity to socialize and exchange valuable information with other members.
