For a Flyfisherman its all about reading the water and picking the best fly to get a strike. Lake Arenal posses its own set of fishing conditions. If you can cast to the same area several times, close to shore, then you have a very good chance of fighting with a guapote. Most every fish is taken within inches or a foot from shore. Fast is an understatment for the strike of a guapote, all your fly needs to do is land in the vicinity, with a couple twitches, its fish on.
