3RMAS (3 Rivers Marine Aquarium Society) is a non-profit organization whose membership consists of individuals from the greater Pittsburgh area and beyond. 3RMAS is currently run by an elected board of directors, who donate a lot of time and effort into making the club better for it’s members. 


It is our desire as an organization to educate our members and the general public on proper husbandry of captive marine aquarium life and the conservation of the delicate coral reef ecosystem. We will foster a sense of community through the open exchange of information regarding reef conservation and hobby self-sustainability through teaching the tools and techniques of captive propagation of coral, fish and invertebrates.

We strive to maintain a positive relationship between our members and those scientific and educational institutions currently providing information in the fields of marine biology and reef conservation. We feel that it is through the free exchange of ideas, techniques and problem solving that we can advance captive reef keeping. Members should strive to provide a friendly and welcoming environment to each other and any and all guests.
