The final prompt for the #SundayFishSketch #SciArtSeptember crossover event is “happily ever after.” What better for a classic fairy tale ending than a ridiculously colorful yellow flanked fairy wrasse. What a fun month!

Picked this oddball (to me) weakly electric fish from the Lower Nile and Lake Victoria. #SundayFishSketch + #SciArtSeptember week 3. Prompt = beastly.
