Taxonomic identifications and wild populations are distinct from commercial lines. Aquapedia marks uncertainties and never invents pedigrees, awards or collection localities.
Identity and native range
Osteoglossum bicirrhosum inhabits Amazon and adjacent northern South American freshwater basins. It is not the silver-colored Asian Scleropages trade form.
Breeding
Male mouthbrooding is documented. An Oryx field study highlights risks when fishing crews kill brood-carrying males to collect aquarium juveniles.
Aquarium welfare
Even juveniles grow into large jump-prone fish, with substantial swimming-space and water quality needs. Captive husbandry should not normalize destructive wild fry harvest.
Research sources
Sources support the relevant claims discussed above; unresolved local records remain under review.
