Hello Larry,
I'm from Florida so I catch all sorts of exotics along with native species at some large lakes and canals I fish from regularly.
I caught a nice Pacu 20 pounder not too long ago using a live tilapia. Maybe it was luck .But for some reason I haven't had any luck hooking with these fish after that. Have you ever caught them and is there a good bait or lure you know of that works well. There are some in my lake pushing 40 pounds I would like to have a go at, they fight great. But for some reason are pretty hard to entice to hit anything.
