Beast man it's not that they are conditioned to pellets but rather to humans...those fish are still eating other natural foods, it's just they get super smart and know when people are around and even when they don't know your around they can see your line and hooks, etc...they become by far the smartest fish I have ever seen...

Fast baits like a rattle trap I have been able to get em to bite on, but even then I watch them race in and swirl off short at the last second once they figure out its not real...
