Where is the Silver Arowana (*Osteoglossum bicirrhosum*) found natively, contrasting with the Asian Arowana's habitat?
Answer
The floodplains of the Amazon River Basin in South America
The broader arowana group comprises species distributed across various continents, and the Silver Arowana represents the South American contingent. This species, scientifically named *Osteoglossum bicirrhosum*, is indigenous to the vast and complex aquatic systems of the Amazon River Basin located in South America. While it is a common find in the global aquarium trade due to its imposing size, its cultural and monetary value typically does not reach the high levels associated with its Asian relatives. Its native environment contrasts sharply with the Southeast Asian and Indonesian ranges where the highly prized *Scleropages formosus* varieties originate.
