Brachyplatystoma platynemum is a large Pimolodus catfish from the Amazone river system that grows 100 cm maximum. In the natural habitat this species migrates as a juvenile from the riverdelta upstream. Some populations are known to migrate over a distance of 3.000 km. There is no need to point out that this is an active species. It is tolerant towards fish of their own size, but will swallow smaller fish.
