    Short Teaser about event


Unfortunately, RMCA had an issue with their speaker for January, so we will be cancelling our combined meeting this Friday, January 14th.

Our next scheduled meeting is February 4th - more details to come.



The Colorado Aquarium Society, established in 1947, is an open group for aquarists to share their interest in all facets of the aquarium hobby. Our members consist of advanced expert hobbyists as well as beginners and all levels between. Our monthly meetings are open to the public and everyone is welcome!
