Sunday's fish pictures

Native name "Dentudo" (Oligosarcus Hepsetus). This fish can be found in many fresh water rivers and lagoons here in Argentina. Normally is taken when we're looking for other fish like Dorado or Tarariras, but he itself could be a great fly fishing option if we use the correct stuff.
I prefer to use one of my Short Series Rods the 5' 10" with a #3 line and dry flies.
