Unknown

Overview

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

The Rihmasuomutetra faces significant pressure from deforestation and agricultural expansion throughout its limited range in the Amazon basin. Water pollution from mining activities and agricultural runoff degrades the pristine stream conditions this species requires for breeding and feeding. Dam construction and water diversions alter natural flow patterns, fragmenting populations and reducing suitable habitat connectivity.

Threat summary

Habitat

This small characin inhabits clear, fast-flowing streams and tributaries in pristine rainforest areas of the upper Amazon basin. It prefers well-oxygenated waters with rocky or sandy substrates and dense riparian vegetation that provides shade and terrestrial insect prey.
