Overview

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

Trigonostigma somphongsi faces severe population decline primarily due to extensive deforestation and habitat conversion throughout its limited range in Southeast Asia. The species' specialized requirements for pristine forest streams make it particularly vulnerable to logging operations and agricultural expansion. Water pollution from agricultural runoff and urban development further degrades the aquatic ecosystems this fish depends upon for survival.

Threat summary

Habitat

This species inhabits clear, fast-flowing forest streams and tributaries in pristine tropical rainforest environments. It requires well-oxygenated waters with specific temperature and pH conditions found only in undisturbed forest watersheds.
