Due to COVID-19 our Events and Meetings are online until further notice.
Colorado Aquarium Society will NOT be having any in person events or meetings for the rest of 2020, this includes our Fall Auction and Christmas Party.
The CAS Board of Directors endorses and recommends the use of MyFishAuction.com to Sell and/or Buy fish and plants. There is no cost to our members to use this site.
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!
