Hyphessobrycon flammeus

Declining

Overview

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

Hyphessobrycon flammeus faces severe population decline primarily due to extensive habitat destruction in Brazil's Atlantic Forest region, where urban expansion and agricultural conversion have eliminated much of its native stream systems. Water pollution from industrial runoff and agricultural chemicals has degraded remaining aquatic habitats, while dam construction fragments river networks and alters natural flow patterns essential for breeding.

Threat summary

Habitat

This species inhabits slow-moving streams and tributaries within Brazil's Atlantic Forest biome, preferring areas with dense riparian vegetation and soft, acidic waters. It typically occurs in shallow coastal river systems with sandy or muddy substrates and abundant aquatic plants.
