Bade 1915 Killifish Drawing. This picture is unique because the yellowish fish with the carmine horizontal stripe is Fundulopanchax deltaense which was 'discovered' and named in 1974. Consider also that in the year this photo was taken, F. sjostedti (Blue Gularis) had been in the then-nascent aquarium hobby for over a decade. This picture is somewhat of a milestone in the early Killi hobby.
