The Chicagoland Marine Aquarium Society (CMAS) is a nonprofit organization of marine hobbyists brought together by the desire to promote a better understanding of the life we keep in home or office marine aquariums. From the very colorful saltwater fish to the amazing coral formations, their focus is to increase the longevity of marine life in a controlled environment through education and the sharing of ideas. Whether you are just curious about saltwater aquariums or have many tanks of your own, you are sure to enjoy this colorful show.
