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.
Zander
The zander is the European equivalent of the walleye and one of the most prized freshwater predators in Europe. Its excellent low-light vision makes it a crepuscular hunter. Its delicate white flesh is considered among the finest of freshwater fish.
