In waters that are "just right" across America, you can find colorful, unfamiliar fish living on the edge. Embark on a weird treasure hunt with Katrina, Guy, and guest Matt Miller from The Nature Conservancy to learn about Central American Convict Cichlids in Idaho to feral fancy guppies in George Washington's Bathtub and Jack Dempsey Cichlids in South Dakota. We explore American's bizarre relationship with certain fish, as well as tips for travel to and fishing hot springs. Unfortunately, this isn't a fairy tale: we also learn how introducing unwanted aquarium pets into hot springs puts our own unique native fish at risk.
