Ancistrus formoso
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Ancistrus formoso faces significant pressure from habitat degradation in its native Brazilian river systems, particularly from agricultural runoff and sedimentation that affects water quality. Deforestation in surrounding watersheds has increased erosion and altered natural flow patterns, while dam construction fragments populations and disrupts breeding cycles. The species' limited geographic range makes it especially vulnerable to localized environmental changes and pollution events.
Habitat
This armored catfish inhabits fast-flowing rocky streams and rivers in the Brazilian Atlantic Forest region, typically found in areas with strong currents and rocky substrates. It prefers well-oxygenated waters with natural vegetation cover along the banks.
