Aphyocheirodon hemigrammus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Aphyocheirodon hemigrammus faces significant pressure from deforestation and agricultural expansion throughout its range in the Amazon Basin. Water pollution from mining activities and agricultural runoff degrades the clear, soft-water streams this species requires for breeding and feeding. Dam construction and river channelization further fragment its already limited habitat, while the aquarium trade creates additional collection pressure on wild populations.
Habitat
This small characin inhabits clear, soft-water streams and tributaries in the Amazon Basin, typically found in areas with moderate current and abundant aquatic vegetation. The species prefers shallow waters with sandy or muddy substrates and requires stable water chemistry for successful reproduction.
