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. If you are interested in learning about the hobby, sharing your experience in the hobby, or would like to discuss any aspect of fish, invertebrates, plants, aquariums, ponds, and amphibians, The Colorado Aquarium Society General Meetings take place the first Friday of each month except July and December when we have parties instead.  Our meetings are open to the public and everyone is welcome!  We have a public auction twice a year in the Spring and Fall, mini-auctions at each meeting, and special events though out the year. Please see below for current dates. Each meeting has a Bowl Show where members show their fish and/or invertebrates for prizes and ribbons. Other programs we have are Grow Competitions (both fish and plants), Aquarist of the Year, and more. Members who place in these competitions are awarded points that are accumulated towards a number of different awards.  For details on these programs and all our activities, rules, and guidelines use the menu above.

COVID-19 Corona Virus cautions and closings are preventing us from meeting.  When this changes we will post it here, on Facebook, and by email.  So, our Meetings are canceled till further notice.
