Actually Skeet, if you look closely, that warmouth does show diagonal stripes from eye. Some fish species, including warmouth, don't necessarily show vivid markings. I now find after catching dozens in the last 10 days, is the increased size of their mouth and the body shaped more like a bass = Warmouth bass. Many of the ones I recently inspected, showed no "war paint"! What they lack in overall size is easily made up with attitude and excellent eating!
The spotted sunfish(stumpknockers) are the tinier ones with black pepper flecks all over also great to eat. Even hear a rumor a few days ago that they are being erroneously served as Grouper cheeks, probably cookie cutter round cut.
