Costa Rica is home to one of the most thrilling freshwater fly fishing experiences: targeting the powerful and aggressive machaca. Often referred to as «mini tarpon» due to their acrobatics, these fish provide an exciting challenge for anglers of all levels.
Costa Rica is a privileged country when it comes to machaca fishing, as it is home to numerous freshwater rivers and lakes, particularly in lowland areas, where this exciting species thrives. The variety of rivers spread across different regions of the country offers an incredible opportunity for anglers to experience the thrill of fishing for machaca in diverse and beautiful settings.

Machaca are distant relatives of the Amazonian piranha, but unlike their carnivorous cousins, they are primarily herbivorous. Their diet consists mostly of:
Fruits
Seeds
Flowers
Insects (especially as juveniles)
Despite their vegetarian tendencies, machaca are aggressive feeders, striking topwater flies and lures with explosive force.
Machaca typically weigh between 2-6 lbs, but some individuals can grow up to 15 lbs. They are known for their aerial displays, often leaping multiple times when hooked, much like tarpon. Their powerful runs and determination make them a sought-after catch for fly anglers.
We also offer multi-day fishing adventures for those who want to maximize their time on the water and explore the best fishing spots.
To effectively target machaca, consider using:
Rod: 6-8 weight fast-action fly rod
Reel: A reel with a smooth drag system
Line: Floating fly line for topwater action
Leader: 16-20 lb test with a 30 lb fluorocarbon bite tippet
We also include all the necessary gear for your fishing tour, so you don’t have to worry about bringing your own equipment. We’ve got you covered with everything you need for a successful machaca fishing experience!
Since machaca feed on fruit and insects, the best flies mimic their natural diet:
Poppers (Green, Yellow, Red, Orange) – Imitate falling fruit
Cork or Foam Fruit Flies – Resemble natural food sources
Dragonfly Imitations – Match seasonal hatches
Black and White Patterns – Mimic bird droppings, a favorite machaca snack
