I think everyone knows of the predatory instincts of Esox, Zeds, Perch and Chub. But if you fish deadbaits at Grafton Mere in Yorks, whilst waiting for a 'Cat' to take your bait you'll get plenty of runs from Carp. Also Loch Maben in Scotland used to be fished regularly with a black Mepps for the big Bream. As Esox20 says All fish are predatory, just some to a greater degree than others.
