Colorado Aquarium Society Spring Auction (CO)
Auctions are the club’s main source of revenue. CAS holds two auctions annually: one in the Spring and the other in the Fall. Auction dates and times are published on the web site home page, on Facebook, and posted in local aquarium shops. Auctions are open to the public and are a great opportunity to meet other fish enthusiasts and get great deals on new and used equipment, fish of all kinds and sizes, fish food, aquarium plants, and all sorts of accessories you might need.
