Pseudoplatystoma reticulatum, commonly known as the reticulated catfish, is a species of freshwater fish found primarily in the rivers of South America, particularly the Amazon River basin. This species is recognized for its distinctive pattern of dark spots and stripes on a lighter background, which helps it blend into its natural habitat. It can grow quite large, reaching lengths of up to 1.5 meters (about 5 feet). The reticulated catfish is a carnivorous species, primarily feeding on smaller fish and invertebrates. It plays a significant role in the ecosystem as both a predator and prey. Due to its size and unique appearance, it is also popular in the aquarium trade, although its care requires a large tank and specific water conditions to thrive.
