Color and size
Adults measure about 40–60 mm. Red flank spots without surrounding halos, olive-colored lips and a turquoise anal fin help distinguish it from close relatives. Breeding males also show turquoise on the lower head and breast. The agency account uses Etheostoma jordani, while this catalog uses Nothonotus jordani.
