So I'm sort of an avid fisherman I fish about every weekend but I'm trying to step my game up, every now and then in a video I'll see people talk about clues like the fishes teeth being sharp, red at the top of their mouths from craws, well today I caught a decent sized fish on a fluke and looked in his mouth and saw a tail sticking out of it, so I switched to a rattle trap and the next cast a caught a 4 pounder so I was wondering if there was any more clues or little hints that nature could provide
