Rachoviscus graciliceps

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Rachoviscus graciliceps faces severe pressure from urban expansion and agricultural development throughout its limited range in southeastern Brazil's Atlantic Forest region. Water pollution from industrial discharge and agricultural runoff degrades the clear, fast-flowing streams this species requires for survival. Deforestation removes critical riparian vegetation that maintains water quality and stream stability, while dam construction fragments remaining suitable habitat.

Threat summary

Habitat

This small characin inhabits clear, fast-flowing streams and tributaries within Brazil's Atlantic Forest biome, typically in areas with rocky substrates and well-oxygenated water. The species requires intact riparian forest cover to maintain the specific water quality conditions necessary for its survival.
