Baryancistrus longipinnis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Baryancistrus longipinnis faces severe pressure from the ornamental fish trade, where it is highly sought after as the 'Gold Nugget Pleco' for aquariums worldwide. Dam construction and proposed hydroelectric projects along the Xingu River system threaten to alter critical water flow patterns and sediment deposition that this species requires for breeding. Mining activities and agricultural runoff in the watershed further degrade water quality in its restricted range.
Habitat
This armored catfish inhabits fast-flowing rocky areas of the Xingu River basin in Brazil, particularly favoring areas with strong currents and rocky substrates where it can attach using its specialized sucker mouth. The species requires well-oxygenated waters with specific temperature and flow conditions typical of Amazonian clearwater rivers.
