Dan’s Green Pacu Streamer is an extremely simple fly to tie, which is perfect because pacu, like piranha, chew flies up flies. The Pacu Streamer is, essentially, an oversized, mostly synthetic Woolly Bugger I tied while prepping for my first jungle fishing assignment in Guyana (Mano A Mano P2). It was meant to catch peacock bass and other toothy predators. And it did. But where it excelled was on pacu—in fact it was the only fly that fooled pacu during the trip.
