I've never seen these as adults, but in general, duboulayi have a nice "dressed-up" look due to the dark edges on their fins. When Johannes Graf collected the Oyster Creek location in 2015, he described them as follows: "The basic color is a metallic green with red lines between the scale rows. The yellow sides of the body are a distinctive trait of this variety and set it apart from any other Melanotaenia duboulayi that we know " (Graf, Johannes IGR e.V.).
