Pseudoplatystoma fasciatum

Pseudoplatystoma fasciatum is a popular species in the aquarium trade due to its distinctive appearance and large size. However, its size and active nature require a substantial aquarium with ample swimming space. It is a predatory fish, so it should be housed with similarly sized tank mates to prevent smaller fish from being eaten. Regular water changes and a powerful filtration system are necessary to maintain optimal water quality, given its size and potential waste production. In the wild, it is found in various waters including rivers and floodplains, where it preys on smaller fish and invertebrates. Its diet in captivity should mimic its natural diet, thus including a variety of meaty foods such as fish pieces, shrimp, and commercial pellets formulated for carnivorous fish.
