Cuisine & Edibility
Arapaima
Large, firm white fillets with a mild, clean flavor and low fat; historically a staple protein in Amazonian communities. Often salted and dried; sustainable harvest is tightly regulated.
Dwarf Gourami
Not consumed — popular ornamental labyrinth fish treasured in freshwater aquariums for its vivid red-and-blue striped coloration and calm temperament.
Species Overview
Arapaima
The arapaima is one of the largest freshwater fish in the world, reaching up to 4.5 meters. An obligate air-breather, it must surface every 10-20 minutes to gulp air. Its tongue is bony and used to crush prey against the roof of its mouth.
Dwarf Gourami
The dwarf gourami is a brightly colored labyrinth fish native to the slow-moving waters of South Asia. Males build elaborate bubble nests at the surface for spawning. Its pelvic fins have evolved into long, thread-like feelers used to sense the environment.
