Osteoglossum bicirrhosum
A very large surface-feeding predatory fish that can exceed 3 feet in length. Silver Arowanas require an enormous aquarium footprint, excellent filtration, and a secure lid because they are powerful jumpers.

Treat adult Silver Arowana as a specialized, large-aquarium species. A 250-gallon aquarium should be considered a conservative lower-end target for an adult rather than a comfortable universal standard; a custom tank with substantial length and width is preferable. Provide heavy filtration, excellent water quality, and a secure cover.
