Enjoy a great day at the swap meet then join CLS for a livebearer auction and a great speaker!


Dr. John Lyons of the University of Wisconsin will speak on "The life, death, and rebirth of the goodeid livebearer fauna of the Teuchitlan Springs, Mexico".

"I'll review the natural and human history of these amazing springs, which are (or were) the home of the (relatively) well-known goodeids Ameca splendens, Skiffia francesae, and Zoogoneticus tequila. Then I'll trace the decline and loss of much of the native fauna, and I'll end with the ground-breaking efforts of Mexican conservationists, supported by hobbyists in North America and Europe, to re-introduce and restore extinct fish populations in the springs."

John Lyons 200 212About the speaker

"I’ve been a fish nerd nearly my entire life, observing, catching, and keeping fish for well over 50 years. Currently, I’m Curator of the Fishes at the University of Wisconsin Zoological Museum in Madison, a position I have held since 1985. Until I retired in 2017, I was also a fisheries research scientist and supervisor for the Wisconsin Department of Natural Resources, where I worked for over 32 years. I’m originally from New York State, and I came to Madison, Wisconsin, for graduate school in 1979, loved the area, and never left. I received my B.S. degree in biology from Union College in Schenectady, NY, and my M.S. and Ph.D. in Zoology from the University of Wisconsin-Madison, all with an emphasis on the study of fish. Although I’m interested in all fishes throughout the world, my specialties are the fishes of Wisconsin and the upper Midwest and the freshwater fishes of Mexico. I’ve made 39 (and counting) scientific trips to Mexico and other parts of Latin America, working on a wide variety of species in many different habitats and locations. Currently, much of my focus has been on the conservation of Goodeid livebearers and other fishes in central Mexico. I’m a better field biologist than aquarist, but I currently maintain four species of rare Goodeids at home and at the Zoological Museum."

CLS Donates $1000 to North American Goodeid Working Group

The Chicago Livebearer Society it pleased to announce a donation of $1000 to the North American Goodeid Working Group (NAGWG).

The North American Goodeid Working Group (NAGWG) is an organization dedicated to the conservation, study, and propagation of Goodeid fishes. Goodeids are a family of about 45 small freshwater fishes found in the highlands of central Mexico and the deserts of the southwestern United States. Most species are endangered. NAGWG works to protect Goodeids through support of on-the-ground conservation efforts, research, and captive husbandry. NAGWG members include hobbyists, conservationists, and scientists from throughout the United States, Mexico, and Canada. NAGWG is a standing committee of the American Livebearer Association, a U.S. 501(C)(3) organization, and a component of the international Goodeid Working Group, which includes members from Europe, South America, and Asia.

The donation was funded by a recent Rare Livebearer Auction which was held in January 2018. The club sold over 120 bags of rare and hard to find livebearers and a portion of the proceeds helped offset the dontation.

Build a Dual 20G High Tank Stand

The Chicago Livebearer Society was invited to participate in the 2017 Aquatic Experience Show. This required the club to set up a display in a 10 foot by 10 foot booth. Early on we decided that we would like to have some tanks in the booth to attract the public.

Our goal was to be able to display both wild-type and domestic livebearers. The tanks needed to be at a comfortable viewing height and we knew that we needed a custom rack to do so. Time would not allow us to build a rack from scratch onsite, so we knew we needed a rack that could be bolted together and taken down quickly. The rack would need to be inexpensive and built with materials sourced from local home stores, so 2X4 construction was the method used.

We chose to set up two, 20GH tanks which measure:

  • 24¼ W
  • 12½ D
  • 16¾ H

Since the tanks would be displayed side by side, we knew we needed a stand that was at least 48-1/2" wide. We opted for bit of extra width and went with 49" for the width. As for height, we went for 40” which would offer comfortable viewing for standing patrons.
