Tiger musky - roar - things are true aquatic monsters pound for pound competitive with anything in the world.
Tiger muskies are naturaly occuring but if you want a non hybrid, pound for pound small mouth bass still gets my vote. Large mouths get bigger but in every other way the small mouth has them beat. Their common-ess has robbed them of mystic but small mouth are lighting fast, intellegent, and utterly ravonous predators in their own enviroment. As I have joked before while fishing: despite the piranha natives there swim in the Amazon and rarely if ever come to any harm. If the Small mouth had a piranha's teeth our rivers would not be safe.
