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 bi-monthly 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.

Club Projects:
The SMMAS School Program now has four schools participating in our program to reach the next generation of Marine Hobbyist. Our goal is to teach these children about the dangers our natural reefs face today and what we can do as hobbyist to help.

Little Flower School:
A very nice 75 gallon reef display was set up at the Little Flower School in Great Mills and is being supported by SMMAS members Mike Howell. Classes are being taught to the 4th and 6th graders every week about the dangers our coral reefs face today and how we can save a reef by growing our own. They started with the quick and easy to grow coral xenia; now they are working with other corals as well and seem to enjoy every aspect of marine husbandry. We have discussed virtually all areas of starting and maintaining a saltwater aquarium, with the students actually doing the work themselves. The students have propagated many different types of corals and plan to sell them to help offset the cost of maintaining their reef aquarium. We have also started an after school reef club for those students that want to "kick it up a notch" and become more involved in the hobby.

Kings Christian Academy:
Kings Christian Academy is our second school in the program, with SMMAS members Dana and Cale Benefield supporting Kings Christian Academy. Dana is teaching the 4th and 6th through 10th graders every week on all aspects of Marine aquarium keeping. She is also developing a lesson plan so that SMMAS can document and standardize our teaching program. A very nice 58 gallon Oceanic tank has been set up with donations from SMMAS members and MARCO Rocks to add all those key items that make a salt water aquarium function.
