Mark has been involved in the organized hobby since 1984.  He is a past president of the International Betta Congress, the Indianapolis Aquarium Society and the Bucks County Aquarium Society.  He is a founding member and the inaugural president of the American Labyrinth Fish Association.

Welcome to the Delaware County Aquarium Society (DCAS), where fish-keeping hobbyists and professionals of all ages meet to promote and learn more about care, culture and propagation of all forms of underwater life. In the belief that a social approach to the aquarium hobby can bring new dimension of depth and appreciation and open a door to new friends and possibilities, the club has available a whole host of proven programs open to your participation. We hope to see you at a meeting in the very near future.

Our purposes:
