Sphaerichthys vaillanti
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Sphaerichthys vaillanti faces severe pressure from habitat destruction as peat swamp forests across Southeast Asia are cleared for palm oil plantations and urban development. The species' highly specialized requirements for acidic, tannin-rich blackwater environments make it particularly vulnerable to water quality changes from agricultural runoff and industrial pollution. Collection for the international aquarium trade compounds these pressures, as wild populations are harvested to meet demand for this prized ornamental species.
Habitat
This chocolate gourami inhabits slow-moving, acidic blackwater streams and tributaries within pristine peat swamp forests of Southeast Asia. The species requires heavily vegetated waterways with soft, acidic water conditions and abundant leaf litter that creates the tannin-rich environment essential for its survival.
