They are known by many names such as the fish of the thousand casts, beans, frijoles, sliders etc. A fellow fly angler who has been fishing these waters for years offered to help me, he even showed me a secret location where they are very aggressive. It is amazing and something I had never seen before, they do show their backs when they are sliding back to the deeper water. I'm going fishing tomorrow again, hopefully I'll catch more of those. I will sure post whatever I manage to catch.
Thanks
