An undescribed species of Lake Phalen rainbow darter (Etheostoma cf. caeruleum) from a private collection in Knoxville, Tennessee. Unlike other rainbow darters, this population is notably distinct for it's smaller adult size, different shade of blue, and it's presence in a lake rather than streams. They spawn on several hundred feet of exposed rock in an urban lake in St. Paul, MN, surrounded by large residential homes.
