Brian, there is a Cyprinodon and Related Maintenance Study Group with a
publication, "The Pupfish" headed by Darrell Clendinen, an AKA member in
Castle Rock, CO. He is nearby so contact him for information. You might pay
him a visit as most hobbyists enjoy showing and talking about their killies.
Have a good time; welcome to the world of killifish.
yours, Harry
