The Yellowfin Madtom holds significant historical importance, serving as a catalyst for the establishment of CFI in 1986. Notably, our grant with the Yellowfin stands as the longest ongoing initiative for any Tennessee species. Over the next 5 to 10 years, our primary objective revolves around taking the Yellowfin Madtom off of the Endangered Species list.

An intriguing aspect of Madtoms lies in their nocturnal behavior. While our observation efforts typically commence at dusk, these elusive creatures remain concealed until the sky gets completely dark, revealing only their glowing eyes. Typically we employ spotlights to monitor in deep pools while snorkeling. Additionally, we utilize nets to locate juveniles amidst leaf piles, yet our most effective collection method involves retrieving their nests for incubation in our hatchery.

Male Madtoms exhibit remarkable paternal instincts, often assuming protective roles over their eggs beneath rocks for extended periods, sometimes up to a month. Within our hatchery, we provide specialized shelters, crafted from plant pot saucers, where males diligently tend to their eggs until hatching. Although fasting is common during this period, males may resort to a unique feeding behavior, spinning rapidly to create a suction force for procuring sustenance through their shelter. While instances of cannibalism are rare, desperate circumstances may compel males to consume their own eggs as a last resort against perceived threats.
