Recently I took a trip to the Cachoeira de Iracema, a beautiful waterfall in Presidente Figueredo. We went in the dry season and there was less than 50 percent of the water that usually poured over the rocks. I wanted to catch apistos but I have had very poor luck in that area with apistos. The water is to fast and clear for small nets.
With my fly rod I caught mostly Aequidens tetramerus or diadema and also caught a few pike cichlids.
One of my friends caught the largest fish of the trip a large Hoplias sp. it was surprisingly agile… and it took a bite at my hand.
