Southern Maryland Marine Aquarium Society (SMMAS)
About Us:
The Southern Maryland Marine Aquarium Society (SMMAS) is a friendly gathering of folks from all walks of life that share an interest in Marine Aquariums.  It doesn’t matter if you are a beginner or an expert, we welcome everyone.  We have quarterly meetings to exchange ideas, discuss current conditions in member’s tanks, share and trade corals, and plan field trips.  Our goal is to educate ourselves as well as the general public about the saltwater aquarium hobby and to raise awareness of the delicate reefs we take care of, in and out of our aquariums.
