Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The redtail catfish faces mounting pressure from overfishing across its Amazon basin range, where it is heavily targeted for both commercial fisheries and the international aquarium trade. Dam construction throughout the Amazon river system fragments populations and disrupts the species' extensive migratory patterns essential for reproduction. Deforestation and agricultural runoff degrade water quality in critical spawning areas, while climate change alters seasonal flooding patterns that trigger breeding cycles.
Habitat
Inhabits large river systems throughout the Amazon and Orinoco basins, preferring deep channels and floodplain lakes with strong currents. Adults occupy main river channels while juveniles utilize shallow floodplain areas and tributaries for feeding and shelter.
