Hasemania piatan
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Hasemania piatan faces severe threats from mining activities and urban development within its restricted range in the Chapada Diamantina region of Bahia, Brazil. Water pollution from agricultural runoff and domestic sewage discharge has degraded the quality of streams where this endemic tetra occurs. The species' extremely limited distribution makes it particularly vulnerable to habitat modifications, with entire populations at risk from localized environmental changes.
Habitat
This endemic freshwater fish inhabits clear, fast-flowing streams and small rivers in the Chapada Diamantina highlands of Bahia, Brazil. It typically occurs in rocky substrates with good water quality and moderate to strong current flow.
