Arapaima are the titans of tropical waters, majestic giants that glide through the flooded forests and winding rivers of the Amazon Basin; they embody power, ancient mystery, and the untamed essence of South America’s aquatic wilderness.
Among the largest freshwater fish on Earth, Arapaima are living relics of a primeval world, air-breathing leviathans that can reach lengths over two meters and tip the scales at several hundred pounds. These awe-inspiring creatures, found primarily in the waters of Brazil, Peru, and Colombia, belong to the family Osteoglossidae, a lineage that traces back millions of years.
For adventurous anglers, the Arapaima represents the ultimate freshwater quarry, a fish whose size, strength, and elusiveness make each encounter unforgettable. Known for their explosive surface strikes and raw power, Arapaima challenge even the most experienced fishermen and leave a lasting impression on all who pursue them.
Below is more information about this iconic Amazonian species, along with some of the world’s top destinations to experience the thrill of catching an Arapaima in its wild, jungle-draped home. One click is all it takes to begin your journey into the heart of the rainforest.
Arapaima are legendary sportfish, revered for their immense size, prehistoric presence, and raw, unrelenting power. Reaching lengths of over 8 feet and weighing upwards of 400 pounds, these giants are native to the Amazon Basin and stand among the largest freshwater fish on the planet. Anglers from around the world seek them out not just for their size, but for the patience, precision, and strength it takes to land one.
As apex predators of their realm, Arapaima patrol the slow-moving rivers, oxbow lakes, and flooded forests of South America, feeding on fish, crustaceans, and even birds or small mammals that venture too close to the water’s surface. Their ability to gulp air from the surface makes them unique, and often gives away their presence in otherwise still, murky waters. Fishing for Arapaima typically involves casting large streamers or lures into calm backwaters or using baitfish to tempt a strike from below.
Below, we’ve highlighted some of the world’s top Arapaima fishing destinations—places where adventure meets the extraordinary, deep in the heart of the jungle.
